QNX6 only changes, since SDL-1.2.6-build-2 (which is available in the public
repository):

  • Updated README.QNX file.
  • Fixed building without an OpenGL support.
  • Fixed crashes during intensive window updating under fast machines (over
    200 rectangles for update).
  • Fixed double-buffered fullscreen modes, now it works as needed.
  • Fixed Photon detection algorithm.
  • Fixed HWSURFACE update function.
  • Added SDL_PHOTON_FULLSCREEN_REFRESH environment variable support for
    control refresh rates under Photon.
  • Added 640x400 fullscreen mode emulation via 640x480 (if videodriver not
    supports the original 640x400 mode of course) shifted by 40 vertical pixels
    from begin, to center it. It’s needed for some old ported DOS games which
    ran in doubled 320x200 mode.
  • Added available video ram amount support.
  • Added hardware surface allocation/deallocation support if current
    videomode and videodriver supports it.
  • Added hardware filling support.
  • Added hardware blits support (simple and colorkey). Alpha blit function
    still not available yet.

Hi Mike,

I’m just evaluating SDL 1.2.9 version for QNX 6.3.

It works great as far as I can see. Is the SDL library thread safe ??

Regards

–Armin

Yes, it even has support for threading in it
