   4 # This script is called thus :
   5 #
   6 #   make_opengl [opengl_version]
   7 #
   8 #     - It needs the gl.spec and gl.tm files in the current directory.
   9 #       These files are hosted in the OpenGL extension registry at
  10 #       opengl.org:
  11 #
  12 #       http://www.opengl.org/registry/api/gl.spec
  13 #       http://www.opengl.org/registry/api/gl.tm
  14 #
  15 #       If they are not found in the current directory the script will
  16 #       attempt to download them from there.
  17 #
  18 #       The files used to be hosted and maintained by SGI. You can still find
  19 #       find them in the sample implementation CVS tree which is located at
  20 #       CVS_ROOT/projects/ogl-sample/main/doc/registry/specs.
  21 #       You can also find them on the web at the following URL :
  22 #         http://oss.sgi.com/cgi-bin/cvsweb.cgi/projects/ogl-sample/main/doc/registry/specs/
  23 #
  24 #     - opengl_version is the OpenGL version emulated by the library
  25 #       (can be 1.0 to 1.5). The default is 1.1.
  26 #
  27 # This script generates the three following files :
  28 #
  29 #     - opengl32.spec : the spec file giving all the exported functions
  30 #       of the OpenGL32.DLL library. These functions are the one an
  31 #       application can directly link to (and are all the functions
  32 #       defined in the OpenGL core for the version defined by
  33 #       'opengl_version').
  34 #
  35 #     - opengl_norm.c : this file contains the thunks for all OpenGL
  36 #       functions that are defined in 'opengl32.spec'. The corresponding
  37 #       functions NEED to be defined in Linux's libGL or the library
  38 #       won't be able to be linked in.
  39 #
  40 #     - opengl_ext.c : in this file are stored thunks for ALL possible
  41 #       OpenGL extensions (at least, all the extensions that are defined
  42 #       in the OpenGL extension registry). Contrary to 'opengl_norm.c',
  43 #       you do not need to have these extensions in your libGL to have
  44 #       OpenGL work (as they are resolved at run-time using
  45 #       glXGetProcAddressARB).
