OpenGL2: Add new GL function loader.
2016-07-25 13:30:25 +00:00
// GL function loader, based on https://gist.github.com/rygorous/16796a0c876cf8a5f542caddb55bce8a
Don't link to libGL at compile time Get all OpenGL functions using SDL_GL_GetProcAddress(). This makes it easier to cross-arch compile on Linux and add support for OpenGL ES in the future. Users still have to supply their own libSDL2 for cross-arch compiling on Linux. But now the user does not have to re-install libgl1-mesa-dev package for i386 or amd64 on Debian when switching between compiling ioquake3 for x86 and x86_64.
2017-10-01 23:59:01 +00:00
// get missing functions from code/SDL2/include/SDL_opengl.h
Don't load non-core GL functions for OpenGL 3.2 core context Also declare the GL functions in tr_local.h so there is compile error for non-core GL functions instead of SEGFAULT from dereferencing a NULL pointer. Disable the non-functional stencil shadow code that hasn't been updated to use OpenGL 3.2 core compatible drawing.

Don't load non-core GL functions for OpenGL 3.2 core context Also declare the GL functions in tr_local.h so there is compile error for non-core GL functions instead of SEGFAULT from dereferencing a NULL pointer. Disable the non-functional stencil shadow code that hasn't been updated to use OpenGL 3.2 core compatible drawing.

Don't link to libGL at compile time Get all OpenGL functions using SDL_GL_GetProcAddress(). This makes it easier to cross-arch compile on Linux and add support for OpenGL ES in the future. Users still have to supply their own libSDL2 for cross-arch compiling on Linux. But now the user does not have to re-install libgl1-mesa-dev package for i386 or amd64 on Debian when switching between compiling ioquake3 for x86 and x86_64.
