6 #   make_opengl [opengl_version]
7 #
8 #     - It needs the gl.spec and gl.tm files in the current directory.
9 #       These files are hosted in the OpenGL extension registry at
10 #       opengl.org:

16 #       attempt to download them from there.

18 #       The files used to be hosted and maintained by SGI. You can still find
19 #       find them in the sample implementation CVS tree which is located at

24 #     - opengl_version is the OpenGL version emulated by the library
25 #       (can be 1.0 to 1.5). The default is 1.1.
26 #
27 # This script generates the three following files :
28 #
29 #     - opengl32.spec : the spec file giving all the exported functions
30 #       of the OpenGL32.DLL library. These functions are the one an
31 #       application can directly link to (and are all the functions
32 #       defined in the OpenGL core for the version defined by
33 #       'opengl_version').
34 #
35 #     - opengl_norm.c : this file contains the thunks for all OpenGL
36 #       functions that are defined in 'opengl32.spec'. The corresponding
37 #       functions NEED to be defined in Linux's libGL or the library
38 #       won't be able to be linked in.
39 #
40 #     - opengl_ext.c : in this file are stored thunks for ALL possible
41 #       OpenGL extensions (at least, all the extensions that are defined
42 #       in the OpenGL extension registry). Contrary to 'opengl_norm.c',
43 #       you do not need to have these extensions in your libGL to have
44 #       OpenGL work (as they are resolved at run-time using
45 #       glXGetProcAddressARB).
