# Windows

|
||||
## LLVM and Intel C++ compiler support
|
||||
|
||||
SDL will build with the Visual Studio project files with LLVM-based compilers, such as the Intel oneAPI C++
|
||||
compiler, but you'll have to manually add the "-msse3" command line option
|
||||
to at least the SDL_audiocvt.c source file, and possibly others. This may
|
||||
not be necessary if you build SDL with CMake instead of the included Visual
|
||||
Studio solution.
|
||||
|
||||
Details are here: https://github.com/libsdl-org/SDL/issues/5186
|
||||
|
||||
|
||||
## OpenGL ES 2.x support
|
||||
|
||||
SDL has support for OpenGL ES 2.x under Windows via two alternative
|
||||
implementations.
|
||||
|
||||
The most straightforward method consists in running your app in a system with
|
||||
a graphic card paired with a relatively recent (as of November of 2013) driver
|
||||
which supports the WGL_EXT_create_context_es2_profile extension. Vendors known
|
||||
to ship said extension on Windows currently include nVidia and Intel.
|
||||
|
||||
The other method involves using the
|
||||
[ANGLE library](https://code.google.com/p/angleproject/). If an OpenGL ES 2.x
|
||||
context is requested and no WGL_EXT_create_context_es2_profile extension is
|
||||
found, SDL will try to load the libEGL.dll library provided by ANGLE.
|
||||
|
||||
To obtain the ANGLE binaries, you can either compile from source from
|
||||
https://chromium.googlesource.com/angle/angle or copy the relevant binaries
|
||||
from a recent Chrome/Chromium install for Windows. The files you need are:
|
||||
|
||||
- libEGL.dll
|
||||
- libGLESv2.dll
|
||||
- d3dcompiler_46.dll (supports Windows Vista or later, better shader
|
||||
compiler) *or* d3dcompiler_43.dll (supports Windows XP or later)
|
||||
|
||||
If you compile ANGLE from source, you can configure it so it does not need the
|
||||
d3dcompiler_* DLL at all (for details on this, see their documentation).
|
||||
However, by default SDL will try to preload the d3dcompiler_46.dll to
|
||||
comply with ANGLE's requirements. If you wish SDL to preload
|
||||
d3dcompiler_43.dll (to support Windows XP) or to skip this step at all, you
|
||||
can use the SDL_HINT_VIDEO_WIN_D3DCOMPILER hint (see SDL_hints.h for more
|
||||
details).
|
||||
|
||||
Known Bugs:
|
||||
|
||||
- SDL_GL_SetSwapInterval is currently a no op when using ANGLE. It appears
|
||||
that there's a bug in the library which prevents the window contents from
|
||||
refreshing if this is set to anything other than the default value.
|
||||
|
||||
## Vulkan Surface Support
|
||||
|
||||
Support for creating Vulkan surfaces is configured on by default. To disable
|
||||
it change the value of `SDL_VIDEO_VULKAN` to 0 in `SDL_config_windows.h`. You
|
||||
must install the [Vulkan SDK](https://www.lunarg.com/vulkan-sdk/) in order to
|
||||
use Vulkan graphics in your application.
|
||||
|
||||
## Transparent Window Support
|
||||
|
||||
SDL uses the Desktop Window Manager (DWM) to create transparent windows. DWM is
|
||||
always enabled from Windows 8 and above. Windows 7 only enables DWM with Aero Glass
|
||||
theme.
|
||||
|
||||
However, it cannot be guaranteed to work on all hardware configurations (an example
|
||||
is hybrid GPU systems, such as NVIDIA Optimus laptops).
