Date: Sat, 24 Aug 2002 22:20:01 -0600 From: "Greg Haerr" Subject: Announce: sdl-nanox-patch Sam, I've created an update patch for enhanced Nano-X support with SDL. I've created the patch against SDL-1.2.4. I'd appreciate it if you would apply it to the next SDL version. Enhancements include: 1. Small bugfixes to compile without errors 2. Support for direct client-side framebuffer access with configure option 3. Add dynamic pixel type support for hardware framebuffer; eliminating the need for compile-time configuration option. I've updated the README.NanoX file with the details. This version has been tested with Microwindows v0.89pre9 CVS and SMPEG 0.4.4. I've added multi-threading support to Microwindows to support the multi-threaded SMPEG, and all works fine. To turn on thread safety in Microwindows, use THREADSAFE=Y in the Microwindows config file. Thanks! Regards, Greg Founder, The Microwindows Project http://microwindows.org
