4 # This script is called thus :
6 # make_opengl path_to_spec_file opengl_version
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.
16 # - opengl_version is the OpenGL version emulated by the library
17 # (can be 1.0 to 1.5).
19 # This script generates the three following files :
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
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.
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).
