Install the development packages of OpenGL for your distribution. This will usually install the needed headers into /usr/include/GL but it may very between distros.

I Installed the development packages of OpenGL，and the problem was solved, but another error occurs:

'gluPerspective' was not declared in this scope

what's the matter?

Thanks a lot!

You probably need additional utility packages for OpenGL such as GLU, GLUT, GLEW.
