5 #
6 #   make_opengl path_to_spec_file opengl_version
7 #
8 #     - path_to_spec_file is the path to the directory where the OpenGL
9 #       spec files are located. These files are part of the OpenGL
10 #       sample implementation CVS tree and are located in
11 #       CVS_ROOT/projects/ogl-sample/main/doc/registry/specs.
12 #       You can find them on the web at the following URL :
13 #         http://oss.sgi.com/cgi-bin/cvsweb.cgi/projects/ogl-sample/main/doc/registry/specs/
14 #       You will need gl.tm and gl.spec.
15 #
16 #     - opengl_version is the OpenGL version emulated by the library
17 #       (can be 1.0 to 1.5).
18 #
19 # This script generates the three following files :
20 #
21 #     - opengl32.spec : the spec file giving all the exported functions
22 #       of the OpenGL32.DLL library. These functions are the one an
23 #       application can directly link to (and are all the functions
24 #       defined in the OpenGL core for the version defined by
25 #       'opengl_version').
26 #
27 #     - opengl_norm.c : this file contains the thunks for all OpenGL
28 #       functions that are defined in 'opengl32.spec'. The corresponding
29 #       functions NEED to be defined in Linux's libGL or the library
30 #       won't be able to be linked in.
31 #
32 #     - opengl_ext.c : in this file are stored thunks for ALL possible
33 #       OpenGL extensions (at least, all the extensions that are defined
34 #       in the OpenGL extension registry). Contrary to 'opengl_norm.c',
35 #       you do not need to have these extensions in your libGL to have
36 #       OpenGL work (as they are resolved at run-time using
37 #       glXGetProcAddressARB).
