4 # This script is called thus :
6 # make_opengl [opengl_version]
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
12 # http://www.opengl.org/registry/api/gl.spec
13 # http://www.opengl.org/registry/api/gl.tm
15 # If they are not found in the current directory the script will
16 # attempt to download them from there.
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/
24 # - opengl_version is the OpenGL version emulated by the library
25 # (can be 1.0 to 1.5). The default is 1.1.
27 # This script generates the three following files :
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
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.
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).
