# This script is called thus :
|
|
#
|
|
# make_opengl [opengl_version]
|
|
#
|
|
# - It needs files from the OpenGL extension registry:
|
|
#
|
|
# https://raw.github.com/KhronosGroup/OpenGL-Registry/master/xml/gl.xml
|
|
# https://raw.github.com/KhronosGroup/OpenGL-Registry/master/xml/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.
