Bug 4879

Summary: Build fails with DRM/KMS backend on X11-less distribution

Description Paul Cercueil 2019-11-27 23:07:52 UTC 
On a distribution where X11 is not available, but KMS can be used, SDL2 fails to build.

This is due to the fact that <EGL/eglplatform.h> from Mesa will include <X11/Xlib.h> unless the EGL_NO_X11 macro is set (or MESA_EGL_NO_X11_HEADERS which is deprecated and will trigger a warning).

I believe that if the DRM/KMS backend is enabled, but X11 is not found, the macro should be defined in the CFLAGS. Doing so results in SDL2 compiling and working fine.

That sounds reasonable. Do you have a tested patch that does this?
