It seems OpenGL context can not be created... are you using an old device? Does your GPU support OpenGL 3.3? did you update GPU drivers?

[Yzubi]

I'ts an really old IBM x60s laptop, it don't support opengl 3.3.

glxinfo | grep "OpenGL version"
OpenGL version string: 2.1 Mesa 18.2.2

[raysan5]

That's what I thought... then you should recompile raylib for OpenGL 1.1 or OpenGL 2.1, those options are available to run raylib on old devices.

How do that on Linux? Only found this link, that uses a Notepad++ script: https://github.com/raysan5/raylib/wiki/FAQ

[raysan5]

@Yzubi you can do it with provided Makefile on raylib/src directory. From shell just execute:

raylib/src/> make PLATFORM=PLATFORM_DESKTOP GRAPHICS=GRAPHICS_API_OPENGL_21 -B

libraylib.a should be generated on the same directory, maybe you need to copy it on system libraries path... not sure if examples compilation Makefile looks for it directly on raylib/src, it's possible.

Thanks! It worked! :)

It dosent work for me i have opengl2.1 @raysan5
ihaved tryed i get this error

@arydevy did you recompile raylib for OpenGL 2.1? Maybe your system does not support some OPenGL 2.1 features... You can also try recompiling for OpenGL 1.1.

@arydevy did you recompile raylib for OpenGL 2.1? Maybe your system does not support some OPenGL 2.1 features... You can also try recompiling for OpenGL 1.1.
