Date: Mon, 5 Jan 2004 00:09:36 +0100 From: Anders_F_Bj?rklund Subject: [SDL] Dynamic OpenGL lib support for Mac Here's a patch that adds LoadLibrary and GetProcAddress to the Carbon macintosh driver (for Mac OS 9 and Mac OS X): http://www.algonet.se/~afb/SDL-1.2.6-macdynamicgl.patch It just calls the corresponding function from SDL_loadso. It also fixes one Mac bug in SDL_loadso.c, that made it fail always when loading a library, and fixes the screen update after receiving an update event - which caused the OpenGL context to be overwritten by a blank window by UpdateRect...
