   3 # This script is called thus :
   4 #
   5 #   make_opengl path_to_spec_file opengl_version
   6 #
   7 #     - path_to_spec_file is the path to the directory where the OpenGL
   8 #       spec files are located. These files are part of the OpenGL
   9 #       sample implementation CVS tree and are located in
  10 #       CVS_ROOT/projects/ogl-sample/main/doc/registry/specs.
  11 #       You can find them on the web at the following URL :
  12 #         http://oss.sgi.com/cgi-bin/cvsweb.cgi/projects/ogl-sample/main/doc/registry/specs/
  13 #
  14 #     - opengl_version is the OpenGL version emulated by the library
  15 #       (can be 1.0 to 1.2).
  16 #
  17 # This script generates the three following files :
  18 #
  19 #     - opengl32.spec : the spec file giving all the exported functions
  20 #       of the OpenGL32.DLL library. These functions are the one an
  21 #       application can directly link to (and are all the functions
  22 #       defined in the OpenGL core for the version defined by
  23 #       'opengl_version').
  24 #
  25 #     - opengl_norm.c : this file contains the thunks for all OpenGL
  26 #       functions that are defined in 'opengl32.spec'. The corresponding
  27 #       functions NEED to be defined in Linux's libGL or the library
  28 #       won't be able to be linked in.
  29 #
  30 #     - opengl_ext.c : in this file are stored thunks for ALL possible
  31 #       OpenGL extensions (at least, all the extensions that are defined
  32 #       in the OpenGL extension registry). Contrary to 'opengl_norm.c',
  33 #       you do not need to have these extensions in your libGL to have
  34 #       OpenGL work (as they are resolved at run-time using
  35 #       glXGetProcAddressARB).
