Date: Wed, 22 May 2002 22:30:58 +0300 From: "Mike Gorchak" <> Subject: One more QNX patch Hi ! - Fixed graywin test application. Added properly support for window size not equal to 640x480. - Added support for not aligned pitch of image in SDL_SWSURFACE and SDL_HWSURFACE. Using Photon builtin alignes. - Added memory clear after each malloc to avoid problems in the future :) - Removed unused variables and static variables, fixed some warnings. - Updated readme.QNX file.

    OpenGL in window mode  works well  and  stable, in fullscreen
mode too, but fullscreen mode has not been heavily tested.
    If you have QNX RtP 6.1.0 w/ or w/o Patch A you must download
new Photon3D runtime from The versions
of OS before 6.1.0 are not supported.

1. While  creating  OpenGL  context  software  renderer  mode  is
   artificially selected (QSSL made acceleration only for  Voodoo
   boards in fullscreen mode, sorry but I don't have  this board,
   if you want acceleration - you may remove some line  in source
2. Photon has some errors in detecting  how  much bits  per pixel
   videomode has.
3. No  shared  libraries  yet.  We  need  manually  set  flag  to
   'configure' --disable-shared.
4. Due to Photon API limitation, flag SDL_HWSURFACE supported on-
   ly in case of desktop bpp is equal requested bpp in window mo-

Some building issues:

    Run configure script without x11 support, e.g.:

    a) for OpenGL support:
    ./configure --prefix=/usr/local \
                --disable-video-x11 \

    b) without OpenGL support:
    ./configure --prefix=/usr/local \
                --disable-video-x11 \
                --disable-shared    \

    In test directory  also run  ./configure  script  without x11
support, e.g.:

    ./configure  --with-sdl-prefix=/usr/local      \
                 --with-sdl-exec-prefix=/usr/local \
                 --prefix=/usr/local --without-x
