I am looking for a a short OpenGL geometry shader example that will run on Linux, preferably with as few dependencies as possible. Basically I want to use that program as a test to see if geometry shaders are supported at all on the system it’s currently running on.

    Just use glxinfo (in the package mesa-utils on Ubuntu/Debian) and check the extension list (GL_EXT/ARB_geometry_shader4) or OpenGL version (>= 3.2) for geometry shader support.

    Extension example:

    user@machine:~$ glxinfo | grep "GL_EXT_framebuffer_object"
GL_EXT_framebuffer_multisample, GL_EXT_framebuffer_object,

    Version example:

    user@machine:~$ glxinfo | grep "OpenGL version"
OpenGL version string: 2.1 Mesa 7.10.2
