The default is 1.1. # # This script generates the three following files : # # - opengl32.spec : the spec file giving all the exported functions # of the OpenGL32.DLL library. These functions are the one an # application can directly link to (and are all the functions # defined in the OpenGL core for the version defined by # 'opengl_version'). # # - opengl_norm.c : this file contains the thunks for all OpenGL # functions that are defined in 'opengl32.spec'. The corresponding # functions NEED to be defined in Linux's libGL or the library # won't be able to be linked in. # # - opengl_ext.c : in this file are stored thunks for ALL possible # OpenGL extensions (at least, all the extensions that are defined # in the OpenGL extension registry). Contrary to 'opengl_norm.c', # you do not need to have these extensions in your libGL to have # OpenGL work (as they are resolved at run-time using # glXGetProcAddressARB). # # Copyright 2000 Lionel Ulmer # # This library is free software; you can redistribute it and/or # modify it under the terms of the GNU Lesser General Public # License as published by the Free Software Foundation; either # version 2.1 of the License, or (at your option) any later version. # # This library is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
