4 # This script is called thus :
6 # make_opengl [opengl_version]
8 # - It needs files from the OpenGL extension registry:
10 # http://www.opengl.org/registry/api/gl.spec
11 # http://www.opengl.org/registry/api/gl.tm
12 # http://www.opengl.org/registry/api/wgl.tm
13 # http://www.opengl.org/registry/api/wglext.spec
15 # If they are not found in the current directory the script will
16 # attempt to download them from there.
18 # - opengl_version is the OpenGL version emulated by the library
19 # (can be 1.0 to 1.5). The default is 1.1.
21 # This script generates the three following files :
23 # - opengl32.spec : the spec file giving all the exported functions
24 # of the OpenGL32.DLL library. These functions are the one an
25 # application can directly link to (and are all the functions
26 # defined in the OpenGL core for the version defined by
29 # - opengl_norm.c : this file contains the thunks for all OpenGL
30 # functions that are defined in 'opengl32.spec'. The corresponding
31 # functions NEED to be defined in Linux's libGL or the library
32 # won't be able to be linked in.
34 # - opengl_ext.c : in this file are stored thunks for ALL possible
35 # OpenGL extensions (at least, all the extensions that are defined
36 # in the OpenGL extension registry). Contrary to 'opengl_norm.c',
37 # you do not need to have these extensions in your libGL to have
38 # OpenGL work (as they are resolved at run-time using
39 # glXGetProcAddressARB).
41 # - include/wine/wgl_driver.h: definitions for the tables of OpenGL functions.
