| # make_opengl path_to_spec_file opengl_version |
| # |
| # - path_to_spec_file is the path to the directory where the OpenGL |
| # spec files are located. These files are hosted in the OpenGL |
| # extension registry at opengl.org: |
| # http://www.opengl.org/registry/api/gl.spec |
| # http://www.opengl.org/registry/api/gl.tm |
| # |
| # The files used to be hosted and maintained by SGI. You can still find |
| # find them in the sample implementation CVS tree which is located at |
| # CVS_ROOT/projects/ogl-sample/main/doc/registry/specs. |
| # You can also find them on the web at the following URL : |
| # http://oss.sgi.com/cgi-bin/cvsweb.cgi/projects/ogl-sample/main/doc/registry/specs/ |
| # |
| # - opengl_version is the OpenGL version emulated by the library |
| # (can be 1.0 to 1.5). |
| # |
| # 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). |
