Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

Fixed bug 5463 - generated Wayland interfaces are included in the library's ABI Simon McVittie In versions since 1.15, the `code` mode is a deprecated alias for `public-code`, which emits symbols with default visibility, overriding SDL's -fvisibility=hidden option.

I traced the problem to the cmake/sdlchecks.cmake file at line 1091, which sets flags for the build process. I surrounded the problem flag with double quotes, shown below, and CMake works with spaces in the project directory path.

The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

Fixed bug 3690 - SDL2 KMS/DRM render context support Manuel The attached patch adds support for KMS/DRM context graphics. It builds with no problem on X86_64 GNU/Linux systems, provided the needed libraries are present, and on ARM GNU/Linux systems that have KMS/DRM support and a GLES2 implementation. Tested on Raspberry Pi: KMS/DRM is what the Raspberry Pi will use as default in the near future, once the propietary DispmanX API by Broadcom is overtaken by open graphics stack, it's possible to boot current Raspbian system in KMS mode by adding "dtoverlay=vc4-kms-v3d" to config.txt on Raspbian's boot partition. X86 systems use KMS right away in every current GNU/Linux system. Simple build instructions: $./autogen.sh $./configure --enable-video-kmsdrm $make
