In Linux, The eclips compilation OpenGL cannot be linked to the corresponding library.

In Linux, eclips itself can compile C/C ++, which makes me very pleased, ^ _ ^.

However, OpenGL has been compiled.ProgramIt cannot be compiled. An error is returned:... undefined reference to 'glbegin '.....

The result is that all the glut functions cannot be identified. The reason is that there is no link to the corresponding library. For example, when compiling with GCC on the terminal, you need to manually link several libraries:-lgl-lglu-lglut. Therefore, you need to add these libraries in ipvs. The procedure is as follows:

1. Click properties in the project selection drop-down list.

2. manually add the glut, GL, and Glu databases.
