The default path used by directfb for libGL is different than the default path used by x11 in SDL2:
./src/video/directfb/SDL_DirectFB_opengl.c:
path = "libGL.so";
./src/video/x11/SDL_x11opengl.c:
#define DEFAULT_OPENGL "libGL.so.1"
On at least one distro (Alpine Linux), libGL.so is not created (or more accurately the symlink to libGL.so.1 is not created). For consistency, the 'path' variable in SDL_DirectFB_opengl.c should patch the DEFAULT_OPENGL in SDL_x11opengl.c ("libGL.so.1")
