| ## 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. | |
