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