glXCreateContextAttribsARB not found
freeglut, mesa, opengl
Solution
The `glXCreateContextAttribsARB` API requires GLX 1.4, and at least OpenGL 3.0 (but really 3.2).

Your GPU driver is reporting it is only capable of OpenGL 2.1, which is consistent with using Mesa 7.x. The latest Mesa 8.x does support OpenGL 3, but you would need to check if it is available for your distro and also supports your particular GPU model.
Bottom line - you might be limited by your hardware and driver to the old 2.1 driver model, which means you can't take advantage of the "Modern" approach. Sorry!

Problem
I'm going through Learning Modern 3D Graphics Programming, and I'm trying to run the "hello, world!" triangle program. However, I get this error: ``` jason@ubuntu:~/Desktop/Tutorial 0.3.8/Tut 01 Hello Triangle$ ./Tut\ 01\ Main freeglut (./Tut 01 Main): glXCreateContextAttribsARB not found ``` Running 'glxinfo' gives me this: ``` jason@ubuntu:~/Desktop/Tutorial 0.3.8/Tut 01 Hello Triangle$ glxinfo | grep OpenGL OpenGL vendor string: Tungsten Graphics, Inc OpenGL renderer string: Mesa DRI Intel(R) Ironlake Mobile OpenGL version string: 2.1 Mesa 7.11 OpenGL shading language version string: 1.20 OpenGL extensions: ``` And a 'lspci' command gives me this: ``` jason@ubuntu:~/Desktop/Tutorial 0.3.8/Tut 01 Hello Triangle$ lspci | grep "VGA" 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) ``` Through a bit of googling, I'm guessing that I'm using OpenGL 2.1 when I should be using OpenGL 3.3 for 'glXCreateContextAttribsARB', though I don't really know. Is there anything I can do?
