Subject: Re: About QNX support in SDL 1.3
Here is another batch of patches.
1) Makefile.in - added SDL_opengles.h header as header to install.
2) configure.in - Added special define to detect Common Lite OpenGL ES
library in case if Common library is not installed. Added check for
clock_gettime in libc (in QNX it is in libc).
3) SDL_config.h.in - Added SDL_VIDEO_RENDER_OPENGL_ES and
SDL_VIDEO_OPENGL_ES declarations for configure script autodetection.
4) SDL_opengles.h - Added GL_API definition if it is not defined. Added
extension GL_OES_draw_texture because OpenGL ES Renderer uses it without
declaration. Added GL_OES_vertex_buffer_object extension, which is supported
under QNX OpenGL ES. Added GL_OES_single_precision extension.
5) To the test directory I've added building OpenGL ES test applications
through the autotools suite. Was support for iPhone IDE building only.

================================================================= Patch version 0.9 of SDL(Simple DirectMedia Layer) for Nano-X API ================================================================= Authors: Hsieh-Fu Tsai, clare@setabox.com Greg Haerr, greg@censoft.com This patch is against SDL version 1.2.4. It enhances previous patch 0.8 by providing direct framebuffer access as well as dynamic hardware pixel type support, not requiring a compile-time option setting for different framebuffer modes. Tested against Microwindows version 0.89pre9. Older Microwindows versions =========================== If running on a version older than Microwindows 0.89pre9, the following items might need to be patched in Microwindows. 1. Patch src/nanox/client.c::GrClose() It fixes the client side GrClose(). In the original version, GrOpen() can only be called once. When the GrOpen() is called at the second time, the program will terminate. In order to prevent this situation, we need to insert "nxSocket = -1" after "close(nxSocket)" in GrClose(). If you do not have this problem, you may skip this step. 2. Patch src/nanox/clientfb.c to return absolute x,y coordinates when using GrGetWindowFBInfo(). Copy the version 0.89pre9 of src/nanox/clientfb.c to your system, or configure using --disable-nanox-direct-fb. ============= Quick Install ============= 1. ./configure --disable-video-x11 --disable-video-fbcon \ --enable-video-nanox \ --with-nanox-pixel-type=[rgb/0888/888/565/555/332/pal] 2. make clean 3. make 4. make install (as root) ============ Nitty-gritty ============ --enable-nanox-direct-fb Use direct framebuffer access --enable-nanox-debug Show debug messages --enable-nanox-share-memory Use shared-memory to speed up When running multi-threaded applications using SDL, such as SMPEG, set THREADSAFE=Y in Microwindows' config file, to enable GrXXX() system call critical section support. ============================================= Some programs can be used to test this patch. ============================================= 1. http://www.cs.berkeley.edu/~weimer/atris (a tetris-like game) 2. http://www.libsdl.org/projects/newvox/ 3. http://www.libsdl.org/projects/xflame/ 4. http://www.libsdl.org/projects/optimum/ 5. http://www.gnugeneration.com/software/loop/ 6: http://www.lokigames.com/development/smpeg.php3 (SMPEG version 0.4.4) ========= Todo List ========= 1. Create hardware surface 2. Create YUVOverlay on hardware 3. Use OpenGL 4. Gamma correction 5. Hide/Change mouse pointer 6. Better window movement control with direct fb access 7. Palette handling in 8bpp could be improved ===================== Supporting Institutes ===================== Many thanks to go to Setabox Co., Ltd. and CML (Communication and Multimedia Laboratory, http://www.cmlab.csie.ntu.edu.tw/) in the Department of Computer Science and Information Engineering of National Taiwan University for supporting this porting project.
