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
