   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 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
  13 #
  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/
  19 #
  20 #     - opengl_version is the OpenGL version emulated by the library
  21 #       (can be 1.0 to 1.5).
  22 #
  23 # This script generates the three following files :
  24 #
  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').
  30 #
  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.
  35 #
  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).
