## 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.

## 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
|
2016-05-18 05:53:35 +00:00
|
|
|
to ship said extension on Windows currently include nVidia and Intel.
|
|
|
|
|
|
2024-02-12 03:10:54 +00:00
|
|
|
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
|
2024-02-12 03:10:54 +00:00
|
|
|
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)
|
|
|
|
|
|
2016-05-18 05:53:35 +00:00
|
|
|
If you compile ANGLE from source, you can configure it so it does not need the
|
2024-02-12 03:10:54 +00:00
|
|
|
d3dcompiler_* DLL at all (for details on this, see their documentation).
|
2016-05-18 05:53:35 +00:00
|
|
|
However, by default SDL will try to preload the d3dcompiler_46.dll to
|
2024-02-12 03:10:54 +00:00
|
|
|
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:
|
2024-02-12 03:10:54 +00:00
|
|
|
|
|
|
|
|
- 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.
