- $Log: glu.pas,v $
- Revision 1.3 2004/10/07 21:01:29 savage
- Fix for FPC
-
- Revision 1.2 2004/08/14 22:54:30 savage
- Updated so that Library name defines are correctly defined for MacOS X.
-
- Revision 1.1 2004/03/30 21:53:54 savage
- Moved to it's own folder.
-
- Revision 1.4 2004/02/20 17:09:55 savage
- Code tidied up in gl, glu and glut, while extensions in glext.pas are now loaded using SDL_GL_GetProcAddress, thus making it more cross-platform compatible, but now more tied to SDL.
-
- Revision 1.3 2004/02/14 00:23:39 savage
- As UNIX is defined in jedi-sdl.inc this will be used to check linux compatability as well. Units have been changed to reflect this change.
-
- Revision 1.2 2004/02/14 00:09:19 savage
- Changed uses to now make use of moduleloader.pas rather than dllfuncs.pas
-
- Revision 1.1 2004/02/05 00:08:19 savage
- Module 1.0 release
-
- Revision 1.4 2003/06/02 12:32:13 savage
- Modified Sources to avoid warnings with Delphi by moving CVS Logging to the top of the header files. Hopefully CVS Logging still works.
-
- Revision 1.3 2003/05/29 22:55:00 savage
- Make use of new DLLFunctions
-
- Revision 1.2 2003/05/27 09:39:53 savage
- Added better Gnu Pascal support.
-
- Revision 1.1 2003/05/11 13:18:03 savage
- Newest OpenGL Headers For Delphi, Kylix and FPC
-
- Revision 1.2 2002/10/13 14:36:47 sg
- * Win32 fix: The OS symbol is called "Win32", not "Windows"
-
- Revision 1.1 2002/10/13 13:57:31 sg
- * Finally, the new units are available: Match the C headers more closely;
- support for OpenGL extensions, and much more. Based on the Delphi units
