| # This script is called thus : | |
| # | |
| # make_opengl [opengl_version] | |
| # | |
| # - It needs files from the OpenGL extension registry: | |
| # | |
| # https://cvs.khronos.org/svn/repos/ogl/trunk/doc/registry/public/api/gl.xml | |
| # https://cvs.khronos.org/svn/repos/ogl/trunk/doc/registry/public/api/wgl.xml | |
| # | |
| # If they are not found in the current directory the script will | |
| # attempt to download them from there. | |
| # | |
| # - opengl_version is the OpenGL version emulated by the library | |
| # (can be 1.0 to 1.5). 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). | |
| # | |
| # - include/wine/wgl_driver.h: definitions for the tables of OpenGL functions. | |
