Hi all, i am trying to learn opengl programming using c++ or c. i read some tutorials and was told that i could not install mesa since i installed the linux version driver for my geforce2 MX400. I was also told that i should include glut.h in my code.but i cannot find this header file in my /usr/include/GL file.Here is the list of files which are now in my GL file: glext.h, gl.h, glx.h, glxtoken.h when i compile the source codes downloaded from Internet using gcc it always says "GL/glut.h file does not exist".can someone help solve this problem?thanks in advance. yufan
