cmake: use pkg-config's library dirs as hint for finding a shared library
2022-10-19 17:11:39 -06:00
include(CMakeParseArguments)
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 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().

The UE version unset all rects when passing `NULL` as a parameter for `window`, this has been removed as it was an unused feature anyhow.

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. Use the `private-code` mode instead. This emits symbols with hidden visibility, so they do not affect the ABI of libSDL.

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().

wayland: Keep protocol XML files in-tree. Now you don't need the latest Wayland installed to build with newer protocols supported, as they'll build correctly; even if your system can't use them, we can make intelligent decisions at runtime about what's available on the current machine anyhow. This also simplifies some logic and possible failure cases in the configure and CMake scripts. Fixes Bugzilla #4207.

cmake: sdlchecks.cmake: pass cflags to the appropriate cmake variable If egl.pc sets at least two macros as the i.MX Vivante driver does, e.g.: | Cflags: -I${includedir} -DLINUX -DWL_EGL_PLATFORM then we get the following error during configuration: | -- Performing Test HAVE_OPENGL_EGL | CMake Error: Parse error in command line argument: WL_EGL_PLATFORM | Should be: VAR:type=value If one changes to add a value to the macro, e.g. | Cflags: -I${includedir} -DLINUX=1 -DWL_EGL_PLATFORM=1 then cmake does not error out but the macro is not passed to the C compiler. CMAKE_REQUIRED_FLAGS is the wrong variable to pass the CFLAGS in, CMAKE_REQUIRED_DEFINITIONS should be used. Signed-off-by: Max Krummenacher <max.krummenacher@toradex.com>

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().

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

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
