# 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.
