Why Could glGetString(GL_VERSION) Be Causing a Seg Fault? [duplicate]

I'm learning OpenGL on Fedora 13 and noticed that a call to glGetString is causing a seg fault. I've scraped Google, but come up with no solutions.

The code is simple:

#include <GL/gl.h> int main() { glGetString(GL_VERSION); return 0; } 

Compile Command:

g++ -lGL main.cpp -o test.bin 

Run result:

$ ./test.bin Segmentation fault (core dumped) 

OpenGL Info:

$ glxinfo | grep OpenGL OpenGL vendor string: Tungsten Graphics, Inc OpenGL renderer string: Mesa DRI Intel(R) IGDNG_M GEM 20100328 2010Q1 OpenGL version string: 2.1 Mesa 7.8.1 OpenGL shading language version string: 1.20 OpenGL extensions: 

Any ideas or references are greatly appreciated.

Solution:

#include <iostream> #include <GL/freeglut.h> int main(int argc, char **argv) { glutInit(&argc, argv); glutInitDisplayMode(GLUT_RGBA); glutCreateWindow("test"); glutFullScreen(); std::cout << glGetString(GL_VERSION) << std::endl; return 0; }
