# Building HIDAPI using Autotools (deprecated)
---
**NOTE**: for all intentions and purposes the Autotools build scripts for HIDAPI are _deprecated_ and going to be obsolete in the future.
HIDAPI Team recommends using CMake build for HIDAPI.
If you are already using Autotools build scripts provided by HIDAPI,
consider switching to CMake build scripts as soon as possible.
---
To be able to use Autotools to build HIDAPI, it has to be [installed](#installing-autotools)/available in the system.
Make sure you've checked [prerequisites](BUILD.md#prerequisites) and installed all required dependencies.
## Installing Autotools
HIDAPI uses few specific tools/packages from Autotools: `autoconf`, `automake`, `libtool`.
On different platforms or package managers, those could be named a bit differently or packaged together.
You'll have to check the documentation/package list for your specific package manager.
### Linux
On Ubuntu the tools are available via APT:
```sh
sudo apt install autoconf automake libtool
```
### FreeBSD
FreeBSD Autotools can be installed as:
```sh
pkg_add -r autotools
```
Additionally, on FreeBSD you will need to install GNU make:
```sh
pkg_add -r gmake
```
## Building HIDAPI with Autotools
A simple command list, to build HIDAPI with Autotools as a _shared library_ and install in into your system:
```sh
./bootstrap # this prepares the configure script
./configure
make # build the library
make install # as root, or using sudo, this will install hidapi into your system
```
`./configure` can take several arguments which control the build. A few commonly used options:
```sh
--enable-testgui
# Enable the build of Foxit-based Test GUI. This requires Fox toolkit to
# be installed/available. See README.md#test-gui for remarks.
--prefix=/usr
# Specify where you want the output headers and libraries to
# be installed. The example above will put the headers in
# /usr/include and the binaries in /usr/lib. The default is to
# install into /usr/local which is fine on most systems.
--disable-shared
# By default, both shared and static libraries are going to be built/installed.
# This option disables shared library build, if only static library is required.
```
## Cross Compiling
This section talks about cross compiling HIDAPI for Linux using Autotools.
This is useful for using HIDAPI on embedded Linux targets. These
instructions assume the most raw kind of embedded Linux build, where all
prerequisites will need to be built first. This process will of course vary
based on your embedded Linux build system if you are using one, such as
OpenEmbedded or Buildroot.
For the purpose of this section, it will be assumed that the following
environment variables are exported.
```sh
$ export STAGING=$HOME/out
$ export HOST=arm-linux
```
`STAGING` and `HOST` can be modified to suit your setup.
### Prerequisites
Depending on what backend you want to cross-compile, you also need to prepare the dependencies:
`libusb` for libusb HIDAPI backend, or `libudev` for hidraw HIDAPI backend.
An example of cross-compiling `libusb`. From `libusb` source directory, run:
```sh
./configure --host=$HOST --prefix=$STAGING
make
make install
```
An example of cross-comping `libudev` is not covered by this section.
Check `libudev`'s documentation for details.
### Building HIDAPI
Build HIDAPI:
```sh
PKG_CONFIG_DIR= \
PKG_CONFIG_LIBDIR=$STAGING/lib/pkgconfig:$STAGING/share/pkgconfig \
PKG_CONFIG_SYSROOT_DIR=$STAGING \
./configure --host=$HOST --prefix=$STAGING
# make / make install - same as for a regular build
```

# Building HIDAPI using CMake
To build HIDAPI with CMake, it has to be [installed](#installing-cmake)/available in the system.
Make sure you've checked [prerequisites](BUILD.md#prerequisites) and installed all required dependencies.
HIDAPI CMake build system allows you to build HIDAPI in two generally different ways:
1) As a [standalone package/library](#standalone-package-build);
2) As [part of a larger CMake project](#hidapi-as-a-subdirectory).
**TL;DR**: if you're experienced developer and have been working with CMake projects or have been written some of your own -
most of this document may not be of interest for you; just check variables names, its default values and the target names.
## Installing CMake
CMake can be installed either using your system's package manager,
or by downloading an installer/prebuilt version from the [official website](https://cmake.org/download/).
On most \*nix systems, the preferred way to install CMake is via package manager,
e.g. `sudo apt install cmake`.
On Windows CMake could be provided by your development environment (e.g. by Visual Studio Installer or MinGW installer),
or you may install it system-wise using the installer from the official website.
On macOS CMake may be installed by Homebrew/MacPorts or using the installer from the official website.
## Standalone package build
To build HIDAPI as a standalone package, you follow [general steps](https://cmake.org/runningcmake/) of building any CMake project.
An example of building HIDAPI with CMake:
```sh
# precondition: create a <build dir> somewhere on the filesystem (preferably outside of the HIDAPI source)
# this is the place where all intermediate/build files are going to be located
cd <build dir>
# configure the build
cmake <HIDAPI source dir>
# build it!
cmake --build .
# install library; by default installs into /usr/local/
cmake --build . --target install
# NOTE: you need to run install command as root, to be able to install into /usr/local/
```
Such invocation will use the default (as per CMake magic) compiler/build environment available in your system.
You may pass some additional CMake variables to control the build configuration as `-D<CMake Variable>=value`.
E.g.:
```sh
# install command now would install things into /usr
cmake <HIDAPI source dir> -DCMAKE_INSTALL_PREFIX=/usr
```
<details>
<summary>Using a specific CMake generator</summary>
An example of using `Ninja` as a CMake generator:
```sh
cd <build dir>
# configure the build
cmake -GNinja <HIDAPI source dir>
# we know, that CMake has generated build files for Ninja,
# so we can use `ninja` directly, instead of `cmake --build .`
ninja
# install library
ninja install
```
`-G` here specifies a native build system CMake would generate build files for.
Check [CMake Documentation](https://cmake.org/cmake/help/latest/manual/cmake-generators.7.html) for a list of available generators (system-specific).
</details><br>
Some of the [standard](https://cmake.org/cmake/help/latest/manual/cmake-variables.7.html) CMake variables you may want to use to configure a build:
- [`CMAKE_INSTALL_PREFIX`](https://cmake.org/cmake/help/latest/variable/CMAKE_INSTALL_PREFIX.html) - prefix where `install` target would install the library(ies);
- [`CMAKE_BUILD_TYPE`](https://cmake.org/cmake/help/latest/variable/CMAKE_BUILD_TYPE.html) - standard possible values: `Debug`, `Release`, `RelWithDebInfo`, `MinSizeRel`; Defaults to `Release` for HIDAPI, if not specified;
- [`BUILD_SHARED_LIBS`](https://cmake.org/cmake/help/latest/variable/BUILD_SHARED_LIBS.html) - when set to TRUE, HIDAPI is built as a shared library, otherwise build statically; Defaults to `TRUE` for HIDAPI, if not specified;
<details>
<summary>macOS-specific variables</summary>
- [`CMAKE_FRAMEWORK`](https://cmake.org/cmake/help/latest/variable/CMAKE_FRAMEWORK.html) - (since CMake 3.15) when set to TRUE, HIDAPI is built as a framework library, otherwise build as a regular static/shared library; Defaults to `FALSE` for HIDAPI, if not specified;
- [`CMAKE_OSX_DEPLOYMENT_TARGET`](https://cmake.org/cmake/help/latest/variable/CMAKE_OSX_DEPLOYMENT_TARGET.html) - minimum version of the target platform (e.g. macOS or iOS) on which the target binaries are to be deployed; defaults to a maximum supported target platform by currently used XCode/Toolchain;
</details><br>
HIDAPI-specific CMake variables:
- `HIDAPI_BUILD_HIDTEST` - when set to TRUE, build a small test application `hidtest`;
- `HIDAPI_WITH_TESTS` - when set to TRUE, build all (unit-)tests;
currently this option is only available on Windows, since only Windows backend has tests;
<details>
<summary>Linux-specific variables</summary>
- `HIDAPI_WITH_HIDRAW` - when set to TRUE, build HIDRAW-based implementation of HIDAPI (`hidapi-hidraw`), otherwise don't build it; defaults to TRUE;
- `HIDAPI_WITH_LIBUSB` - when set to TRUE, build LIBUSB-based implementation of HIDAPI (`hidapi-libusb`), otherwise don't build it; defaults to TRUE;
**NOTE**: at least one of `HIDAPI_WITH_HIDRAW` or `HIDAPI_WITH_LIBUSB` has to be set to TRUE.
</details><br>
To see all most-useful CMake variables available for HIDAPI, one of the most convenient ways is too use [`cmake-gui`](https://cmake.org/cmake/help/latest/manual/cmake-gui.1.html) tool ([example](https://cmake.org/runningcmake/)).
_NOTE_: HIDAPI packages built by CMake can be used with `pkg-config`, as if built with [Autotools](BUILD.autotools.md).
### MSVC and Ninja
It is possible to build a CMake project (including HIDAPI) using MSVC compiler and Ninja (for medium and larger projects it is so much faster than msbuild).
For that:
1) Open cmd.exe;
2) Setup MSVC build environment variables, e.g.: `vcvarsall.bat x64`, where:
- `vcvarsall.bat` is an environment setup script of your MSVC toolchain installation;<br>For MSVC 2019 Community edition it is located at: `C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\`;
- `x64` -a target architecture to build;
3) Follow general build steps, and use `Ninja` as a generator.
### Using HIDAPI in a CMake project
When HIDAPI is used as a standalone package (either installed into the system or built manually and installed elsewhere), the simplest way to use it is as showed in the example:
```cmake
project(my_application)
add_executable(my_application main.c)
find_package(hidapi REQUIRED)
target_link_libraries(my_application PRIVATE hidapi::hidapi)
```
If HIDAPI isn't installed in your system, or `find_package` cannot find HIDAPI by default for any other reasons,
the recommended way manually specify which HIDAPI package to use is via `hidapi_ROOT` CMake variable, e.g.:
`-Dhidapi_ROOT=<path to HIDAPI installation prefix>`.
_NOTE_: usage of `hidapi_ROOT` is only possible (and recommended) with CMake 3.12 and higher. For older versions of CMake you'd need to specify [`CMAKE_PREFIX_PATH`](https://cmake.org/cmake/help/latest/variable/CMAKE_PREFIX_PATH.html#variable:CMAKE_PREFIX_PATH) instead.
Check with [`find_package`](https://cmake.org/cmake/help/latest/command/find_package.html) documentation if you need more details.
Available CMake targets after successful `find_package(hidapi)`:
- `hidapi::hidapi` - indented to be used in most cases;
- `hidapi::include` - if you need only to include `<hidapi.h>` but not link against the library;
- `hidapi::winapi` - same as `hidapi::hidapi` on Windows; available only on Windows;
- `hidapi::darwin` - same as `hidapi::hidapi` on macOS; available only on macOS;
- `hidapi::libusb` - available when libusb backend is used/available;
- `hidapi::hidraw` - available when hidraw backend is used/available on Linux;
**NOTE**: on Linux often both `hidapi::libusb` and `hidapi::hidraw` backends are available; in that case `hidapi::hidapi` is an alias for **`hidapi::hidraw`**. The motivation is that `hidraw` backend is a native Linux kernel implementation of HID protocol, and supports various HID devices (USB, Bluetooth, I2C, etc.). If `hidraw` backend isn't built at all (`hidapi::libusb` is the only target) - `hidapi::hidapi` is an alias for `hidapi::libusb`.
If you're developing a cross-platform application and you are sure you need to use `libusb` backend on Linux, the simple way to achieve this is:
```cmake
if(TARGET hidapi::libusb)
target_link_libraries(my_project PRIVATE hidapi::libusb)
else()
target_link_libraries(my_project PRIVATE hidapi::hidapi)
endif()
```
## HIDAPI as a subdirectory
HIDAPI can be easily used as a subdirectory of a larger CMake project:
```cmake
# root CMakeLists.txt
cmake_minimum_required(VERSION 3.4.3 FATAL_ERROR)
add_subdirectory(hidapi)
add_subdirectory(my_application)
# my_application/CMakeLists.txt
project(my_application)
add_executable(my_application main.c)
# NOTE: no `find_package` is required, since HIDAPI targets are already a part of the project tree
target_link_libraries(my_application PRIVATE hidapi::hidapi)
```
Lets call this "larger project" a "host project".
All of the variables described in [standalone build](#standalone-package-build) section can be used to control HIDAPI build in case of a subdirectory, e.g.:
```cmake
set(HIDAPI_WITH_LIBUSB FALSE) # surely will be used only on Linux
set(BUILD_SHARED_LIBS FALSE) # HIDAPI as static library on all platforms
add_subdirectory(hidapi)
```
<details>
<summary>NOTE</summary>
If you project happen to use `BUILD_SHARED_LIBS` as a `CACHE` variable globally for you project, setting it as simple variable, as showed above _will have not affect_ up until _CMake 3.13_. See [CMP0077](https://cmake.org/cmake/help/latest/policy/CMP0077.html) for details.
</details><br>
There are several important differences in the behavior of HIDAPI CMake build system when CMake is built as standalone package vs subdirectory build:
1) In _standalone build_ a number of standard and HIDAPI-specific variables are marked as _cache variables_ or _options_.
This is done for convenience: when you're building HIDAPI as a standalone package and using tools like `cmake-gui` - those are highlighted as variables that can be changed and has some short description/documentation. E.g.:
![an example of highlighted variables in cmake-gui](documentation/cmake-gui-highlights.png "cmake-gui highlighted variables")<br>
E.g.2:<br>
![an example of drop-down menu in cmake-gui](documentation/cmake-gui-drop-down.png "cmake-gui drop-down menu")<br>
When HIDAPI is built as a _subdirectory_ - **_none of the variables are marked for cache or as options_** by HIDAPI.
This is done to let the host project's developer decide what is important (what needs to be highlighted) and what's not.
2) The default behavior/default value for some of the variables is a bit different:
- by default, none of HIDAPI targets are [installed](https://cmake.org/cmake/help/latest/command/install.html); if required, HIDAPI targets can be installed by host project _after_ including HIDAPI subdirectory (requires CMake 3.13 or later); **or**, the default installation can be enabled by setting `HIDAPI_INSTALL_TARGETS` variable _before_ including HIDAPI subdirectory.
HIDAPI uses [GNUInstallDirs](https://cmake.org/cmake/help/latest/module/GNUInstallDirs.html) to specify install locations. Variables like `CMAKE_INSTALL_LIBDIR` can be used to control HIDAPI's installation locations. E.g.:
```cmake
# enable the installation if you need it
set(HIDAPI_INSTALL_TARGETS ON)
# (optionally) change default installation locations if it makes sense for your target platform, etc.
set(CMAKE_INSTALL_LIBDIR "lib64")
add_subdirectory(hidapi)
```
- HIDAPI prints its version during the configuration when built as a standalone package; to enable this for subdirectory builds - set `HIDAPI_PRINT_VERSION` to TRUE before including HIDAPI;
3) In a subdirectory build, HIDAPI _doesn't modify or set any of the CMake variables_ that may change the build behavior.
For instance, in a _standalone build_, if CMAKE_BUILD_TYPE or BUILD_SHARED_LIBS variables are not set, those are defaulted to "Release" and "TRUE" explicitly.
In a _subdirectory build_, even if not set, those variables remain unchanged, so a host project's developer has a full control over the HIDAPI build configuration.
Available CMake targets after `add_subdirectory(hidapi)` _are the same as in case of [standalone build](#standalone-package-build)_, and a few additional ones:
- `hidapi_include` - the interface library; `hidapi::hidapi` is an alias of it;
- `hidapi_winapi` - library target on Windows; `hidapi::winapi` is an alias of it;
- `hidapi_darwin` - library target on macOS; `hidapi::darwin` is an alias of it;
- `hidapi_libusb` - library target for libusb backend; `hidapi::libusb` is an alias of it;
- `hidapi_hidraw` - library target for hidraw backend; `hidapi::hidraw` is an alias of it;
- `hidapi-libusb` - an alias of `hidapi_libusb` for compatibility with raw library name;
- `hidapi-hidraw` - an alias of `hidapi_hidraw` for compatibility with raw library name;
- `hidapi` - an alias of `hidapi_winapi` or `hidapi_darwin` on Windows or macOS respectfully.
Advanced:
- Why would I need additional targets described in this section above, if I already have alias targets compatible with `find_package`?
- an example:
```cmake
add_subdirectory(hidapi)
if(TARGET hidapi_libusb)
# see libusb/hid.c for usage of `NO_ICONV`
target_compile_definitions(hidapi_libusb PRIVATE NO_ICONV)
endif()
```
## Both Shared and Static build
If you're a former (or present) user of Autotools build scripts for HIDAPI, or you're a package manager maintainer and you're often working with those - you're likely asking how to build HIDAPI with CMake and get both Shared and Static libraries (as would be done by Autotools: `./configure --enable-static --enable-shared ...`).
CMake doesn't have such option of-the-box and it is decided not to introduce any manual CMake-level workarounds for HIDAPI on this matter.
If you want to mimic the Autotools behavior, it is possible by building/installing first the static version of the library and then shared version of the library. The installation folder (`CMAKE_INSTALL_PREFIX`) should point to the same directory for both variants, that way:
- both static and shared library binaries will be available and usable;
- a single header file(s) for both of them;
- Autotools/pkg-config (`.pc`) files will be generated and usable _as if_ generated by Autotools natively and build configured with both `-enable-static --enable-shared` options;
- CMake package scripts will be generated and fully usable, but _only the last build installed_, i.e. if the last was installed Shared version of the binary - CMake targets found by `find_package(hidapi)` would point to a Shared binaries.
There is a historical discussion, why such solution is simplest/preferable: https://github.com/libusb/hidapi/issues/424
#### TL;DR/Sample
```sh
# First - configure/build
# Static libraries
cmake -S <HIDAPI source dir> -B "<build dir>/static" -DCMAKE_INSTALL_PREFIX=<your installation prefix> -DBUILD_SHARED_LIBS=FALSE
cmake --build "<build dir>/static"
# Shared libraries
cmake -S <HIDAPI source dir> -B "<build dir>/shared" -DCMAKE_INSTALL_PREFIX=<your installation prefix> -DBUILD_SHARED_LIBS=TRUE
cmake --build "<build dir>/shared"
# (Optionally) change the installation destination.
# NOTE1: this is supported by CMake only on UNIX platforms
# See https://cmake.org/cmake/help/latest/envvar/DESTDIR.html
# NOTE2: this is not the same as `CMAKE_INSTALL_PREFIX` set above
# NOTE3: this is only required if you have a staging dir other than the final runtime dir,
# e.g. during cross-compilation
export DESTDIR="$STAGING_DIR"
#
# Install the libraries
# NOTE: order of installation matters - install Shared variant *the last*
# Static libraries
cmake --install "<build dir>/static"
# Shared libraries
cmake --install "<build dir>/shared"
```

## Intro
For various reasons, you may need to build HIDAPI on your own.
It can be done in several different ways:
- using [CMake](BUILD.cmake.md);
- using [Autotools](BUILD.autotools.md) (deprecated);
- using [manual makefiles](#building-the-manual-way-on-unix-platforms);
- using `Meson` (requires CMake);
**Autotools** build system is historically the first mature build system for
HIDAPI. The most common usage of it is in its separate README: [BUILD.autotools.md](BUILD.autotools.md).<br/>
NOTE: for all intentions and purposes the Autotools build scripts for HIDAPI are _deprecated_ and going to be obsolete in the future.
HIDAPI Team recommends using CMake build for HIDAPI.
**CMake** build system is de facto an industry standard for many open-source and proprietary projects and solutions.
HIDAPI is one of the projects which use the power of CMake to its advantage.
More documentation is available in its separate README: [BUILD.cmake.md](BUILD.cmake.md).
**Meson** build system for HIDAPI is designed as a [wrapper](https://mesonbuild.com/CMake-module.html) over CMake build script.
It is present for the convenience of Meson users who need to use HIDAPI and need to be sure HIDAPI is built in accordance with officially supported build scripts.<br>
In the Meson script of your project you need a `hidapi = subproject('hidapi')` subproject, and `hidapi.get_variable('hidapi_dep')` as your dependency.
There are also backend/platform-specific dependencies available: `hidapi_winapi`, `hidapi_darwin`, `hidapi_hidraw`, `hidapi_libusb`.
If you don't know where to start to build HIDAPI, we recommend starting with [CMake](BUILD.cmake.md) build.
## Prerequisites:
Regardless of what build system you choose to use, there are specific dependencies for each platform/backend.
### Linux:
Depending on which backend you're going to build, you'll need to install
additional development packages. For `linux/hidraw` backend, you need a
development package for `libudev`. For `libusb` backend, naturally, you need
`libusb` development package.
On Debian/Ubuntu systems these can be installed by running:
```sh
# required only by hidraw backend
sudo apt install libudev-dev
# required only by libusb backend
sudo apt install libusb-1.0-0-dev
```
### FreeBSD:
On FreeBSD, you will need to install libiconv. This is done by running
the following:
```sh
pkg_add -r libiconv
```
### Mac:
Make sure you have XCode installed and its Command Line Tools.
### Windows:
You just need a compiler. You may use Visual Studio or Cygwin/MinGW,
depending on which environment is best for your needs.
## Embedding HIDAPI directly into your source tree
Instead of using one of the provided standalone build systems,
you may want to integrate HIDAPI directly into your source tree.
---
If your project uses CMake as a build system, it is safe to add HIDAPI as a [subdirectory](BUILD.cmake.md#hidapi-as-a-subdirectory).
---
If _the only option_ that works for you is adding HIDAPI sources directly
to your project's build system, then you need:
- include a _single source file_ into your project's build system,
depending on your platform and the backend you want to use:
- [`windows\hid.c`](windows/hid.c);
- [`linux/hid.c`](linux/hid.c);
- [`libusb/hid.c`](libusb/hid.c);
- [`mac/hid.c`](mac/hid.c);
- add a [`hidapi`](hidapi) folder to the include path when building `hid.c`;
- make the platform/backend specific [dependencies](#prerequisites) available during the compilation/linking, when building `hid.c`;
NOTE: the above doesn't guarantee that having a copy of `<backend>/hid.c` and `hidapi/hidapi.h` is enough to build HIDAPI.
The only guarantee that `<backend>/hid.c` includes all necessary sources to compile it as a single file.
Check the manual makefiles for a simple example/reference of what are the dependencies of each specific backend.
## Building the manual way on Unix platforms
Manual Makefiles are provided mostly to give the user an idea what it takes
to build a program which embeds HIDAPI directly inside of it. These should
really be used as examples only. If you want to build a system-wide shared
library, use one of the build systems mentioned above.
To build HIDAPI using the manual Makefiles, change the directory
of your platform and run make. For example, on Linux run:
```sh
cd linux/
make -f Makefile-manual
```
## Building on Windows
To build the HIDAPI DLL on Windows using Visual Studio, build the `.sln` file
in the `windows/` directory.
To build HIDAPI using MinGW or Cygwin using Autotools, use general Autotools
[instruction](BUILD.autotools.md).
Any windows builds (MSVC or MinGW/Cygwin) are also supported by [CMake](BUILD.cmake.md).
If you are looking for information regarding DDK build of HIDAPI:
- the build has been broken for a while and now the support files are obsolete.

GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM

END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program. If not, see <http://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
<program> Copyright (C) <year> <name of author>
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
<http://www.gnu.org/licenses/>.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License. But first, please read
<http://www.gnu.org/philosophy/why-not-lgpl.html>.

HIDAPI is a multi-platform library which allows an application to interface
with USB and Bluetooth HID-Class devices on Windows, Linux, FreeBSD, and macOS.
HIDAPI can be either built as a shared library (`.so`, `.dll` or `.dylib`) or
can be embedded directly into a target application by adding a _single source_
file (per platform) and a single header.<br>
See [remarks](BUILD.md#embedding-hidapi-directly-into-your-source-tree) on embedding _directly_ into your build system.
HIDAPI library was originally developed by Alan Ott ([signal11](https://github.com/signal11)).
It was moved to [libusb/hidapi](https://github.com/libusb/hidapi) on June 4th, 2019, in order to merge important bugfixes and continue development of the library.
## Table of Contents
* [About](#about)
* [Test GUI](#test-gui)
* [Console Test App](#console-test-app)
* [What Does the API Look Like?](#what-does-the-api-look-like)
* [License](#license)
* [Installing HIDAPI](#installing-hidapi)
* [Build from Source](#build-from-source)
## About
### HIDAPI has four back-ends:
* Windows (using `hid.dll`)
* Linux/hidraw (using the Kernel's hidraw driver)
* libusb (using libusb-1.0 - Linux/BSD/other UNIX-like systems)
* macOS (using IOHidManager)
On Linux, either the hidraw or the libusb back-end can be used. There are
tradeoffs, and the functionality supported is slightly different. Both are
built by default. It is up to the application linking to hidapi to choose
the backend at link time by linking to either `libhidapi-libusb` or
`libhidapi-hidraw`.
Note that you will need to install an udev rule file with your application
for unprivileged users to be able to access HID devices with hidapi. Refer
to the [69-hid.rules](udev/69-hid.rules) file in the `udev` directory
for an example.
#### __Linux/hidraw__ (`linux/hid.c`):
This back-end uses the hidraw interface in the Linux kernel, and supports
both USB and Bluetooth HID devices. It requires kernel version at least 2.6.39
to build. In addition, it will only communicate with devices which have hidraw
nodes associated with them.
Keyboards, mice, and some other devices which are blacklisted from having
hidraw nodes will not work. Fortunately, for nearly all the uses of hidraw,
this is not a problem.
#### __Linux/FreeBSD/libusb__ (`libusb/hid.c`):
This back-end uses libusb-1.0 to communicate directly to a USB device. This
back-end will of course not work with Bluetooth devices.
### Test GUI
HIDAPI also comes with a Test GUI. The Test GUI is cross-platform and uses
Fox Toolkit <http://www.fox-toolkit.org>. It will build on every platform
which HIDAPI supports. Since it relies on a 3rd party library, building it
is optional but it is useful when debugging hardware.
NOTE: Test GUI based on Fox Toolkit is not actively developed nor supported
by HIDAPI team. It is kept as a historical artifact. It may even work sometime
or on some platforms, but it is not going to get any new features or bugfixes.
Instructions for installing Fox-Toolkit on each platform is not provided.
Make sure to use Fox-Toolkit v1.6 if you choose to use it.
### Console Test App
If you want to play around with your HID device before starting
any development with HIDAPI and using a GUI app is not an option for you, you may try [`hidapitester`](https://github.com/todbot/hidapitester).
This app has a console interface for most of the features supported
by HIDAPI library.
## What Does the API Look Like?
The API provides the most commonly used HID functions including sending
and receiving of input, output, and feature reports. The sample program,
which communicates with a heavily hacked up version of the Microchip USB
Generic HID sample looks like this (with error checking removed for
simplicity):
**Warning: Only run the code you understand, and only when it conforms to the
device spec. Writing data (`hid_write`) at random to your HID devices can break them.**
```c
#include <stdio.h> // printf
#include <wchar.h> // wchar_t
#include <hidapi.h>
#define MAX_STR 255
int main(int argc, char* argv[])
{
int res;
unsigned char buf[65];
wchar_t wstr[MAX_STR];
hid_device *handle;
int i;
// Initialize the hidapi library
res = hid_init();
// Open the device using the VID, PID,
// and optionally the Serial number.
handle = hid_open(0x4d8, 0x3f, NULL);
if (!handle) {
printf("Unable to open device\n");
hid_exit();
return 1;
}
// Read the Manufacturer String
res = hid_get_manufacturer_string(handle, wstr, MAX_STR);
printf("Manufacturer String: %ls\n", wstr);
// Read the Product String
res = hid_get_product_string(handle, wstr, MAX_STR);
printf("Product String: %ls\n", wstr);
// Read the Serial Number String
res = hid_get_serial_number_string(handle, wstr, MAX_STR);
printf("Serial Number String: (%d) %ls\n", wstr[0], wstr);
// Read Indexed String 1
res = hid_get_indexed_string(handle, 1, wstr, MAX_STR);
printf("Indexed String 1: %ls\n", wstr);
// Toggle LED (cmd 0x80). The first byte is the report number (0x0).
buf[0] = 0x0;
buf[1] = 0x80;
res = hid_write(handle, buf, 65);
// Request state (cmd 0x81). The first byte is the report number (0x0).
buf[0] = 0x0;
buf[1] = 0x81;
res = hid_write(handle, buf, 65);
// Read requested state
res = hid_read(handle, buf, 65);
// Print out the returned buffer.
for (i = 0; i < 4; i++)
printf("buf[%d]: %d\n", i, buf[i]);
// Close the device
hid_close(handle);
// Finalize the hidapi library
res = hid_exit();
return 0;
}
```
You can also use [hidtest/test.c](hidtest/test.c)
as a starting point for your applications.
## License
HIDAPI may be used by one of three licenses as outlined in [LICENSE.txt](LICENSE.txt).
## Installing HIDAPI
If you want to build your own application that uses HID devices with HIDAPI,
you need to get HIDAPI development package.
Depending on what your development environment is, HIDAPI likely to be provided
by your package manager.
For instance on Ubuntu, HIDAPI is available via APT:
```sh
sudo apt install libhidapi-dev
```
HIDAPI package name for other systems/package managers may differ.
Check the documentation/package list of your package manager.
## Build from Source
Check [BUILD.md](BUILD.md) for details.

HIDAPI is a multi-platform library which allows an application to interface with USB and Bluetooth HID-Class devices on Windows, Linux, FreeBSD, and macOS. HIDAPI can be either built as a shared library (.so, .dll or .dylib) or can be embedded directly into a target application by adding a single source file (per platform) and a single header.

hid_write(), the Report ID (or 0x0, for devices with a
single report), followed by the report data (16 bytes). In

#
# SYNOPSIS
#
# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
# This macro figures out how to build C programs using POSIX threads. It
# sets the PTHREAD_LIBS output variable to the threads library and linker
# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
# flags that are needed. (The user can also force certain compiler
# flags/libs to be tested by setting these environment variables.)
#
# Also sets PTHREAD_CC to any special C compiler that is needed for
# multi-threaded programs (defaults to the value of CC otherwise). (This
# is necessary on AIX to use the special cc_r compiler alias.)
#
# NOTE: You are assumed to not only compile your program with these flags,
# but also link it with them as well. e.g. you should link with
# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
#
# If you are only building threads programs, you may wish to use these
# variables in your default LIBS, CFLAGS, and CC:
#
# LIBS="$PTHREAD_LIBS $LIBS"
# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
# CC="$PTHREAD_CC"
#
# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
# (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
#
# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
# PTHREAD_CFLAGS.
#
# ACTION-IF-FOUND is a list of shell commands to run if a threads library
# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
# is not found. If ACTION-IF-FOUND is not specified, the default action
# will define HAVE_PTHREAD.
#
# Please let the authors know if this macro fails on any platform, or if
# you have any other suggestions or comments. This macro was based on work
# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
# Alejandro Forero Cuervo to the autoconf macro repository. We are also
# grateful for the helpful feedback of numerous users.

# This is a sample udev file for HIDAPI devices which lets unprivileged
# users who are physically present at the system (not remote users) access
# HID devices.
# If you are using the libusb implementation of hidapi (libusb/hid.c), then
# use something like the following line, substituting the VID and PID with
# those of your device.
# HIDAPI/libusb
SUBSYSTEMS=="usb", ATTRS{idVendor}=="04d8", ATTRS{idProduct}=="003f", TAG+="uaccess"
# If you are using the hidraw implementation (linux/hid.c), then do something
# like the following, substituting the VID and PID with your device.
# HIDAPI/hidraw
KERNEL=="hidraw*", ATTRS{idVendor}=="04d8", ATTRS{idProduct}=="003f", TAG+="uaccess"
# Once done, optionally rename this file for your application, and drop it into
# /etc/udev/rules.d/.
# NOTE: these rules must have priority before 73-seat-late.rules.
# (Small discussion/explanation in systemd repo:
# https://github.com/systemd/systemd/issues/4288#issuecomment-348166161)
# for example, name the file /etc/udev/rules.d/70-my-application-hid.rules.
# Then, replug your device or run:
# sudo udevadm control --reload-rules && sudo udevadm trigger
# Note that the hexadecimal values for VID and PID are case sensitive and
# must be lower case.
# TAG+="uaccess" only gives permission to physically present users, which
# is appropriate in most scenarios. If you require access to the device
# from a remote session (e.g. over SSH), add
# GROUP="plugdev", MODE="660"
# to the end of the udev rule lines, add your user to the plugdev group with:
# usermod -aG plugdev USERNAME
# then log out and log back in (or restart the system).
