glXGetProcAddress is the linux equivalent, look into it's man page for more details. Or if your using SDL use the function SDL_GL_GetProcAddress, which has the added advantage that it works on windows to.

You should also know that a lot of functionality which on windows is part of the extensions, is part of OpenGL's api on linux (windows is stuck on OpenGL 1.1, linux is not)

Edit: damn, should have hit the edit button

link to the original OpenGL extension for the X windowing system.

You can also use cross-platform libraries, like SDL (as George mentioned) which has complete graphics capabilities, or GLEW which is fully dedicated to OpenGL extensions.
