Hash :4a9c6f0a Message :Fixed bug 3173 - SDL_GL_GetAttribute overwrites error code from SDL_GL_GetProcAddress
Yann Dirson
When SDL_GL_GetProcAddress returns in error, the cause of the error is overwritten
in GL_GL_GetAttribute, reporting to the user "Failed getting OpenGL glGetString entry point", whereas the original "OpenGL library not loaded" never makes it
to the user.
Pushed a fix to:
https://github.com/O-Computers/SDL/commit/f94cb13708ef4d236f8a2a330135b9b3a47db204
Note that the "OpenGL library not loaded" error looks like no root cause either,
and I'm still puzzled by the code path used: I'm forcing opengles2 renderer on
the x11 video driver on a rpi2, as in https://bugzilla.libsdl.org/3169, and although I now know that I must force the use of the RPI video driver instead
of the x11 one, I suspect even more accurate info can be given to user.
