QNX: -= NOT YET SUPPORTED =-
Configuration doesn't work right, Makefiles still need to be
tweaked (need to add libraries to any apps that use sdl_config
to figure out what libs they need).
Only static libraries are being made, no shared ones.
The only hardware surface is the primary view surface.

The software surfaces could use some speed up.
It doesn't look like the OpenGL stuff is there. (did a grep for
PdCreateOpenGLContext, nothing found).
The mouse cursor doesn't look right.

Experimentally added OpenGL support in window mode (in fullscreen
mode not yet). If you have QNX RtP v6.1.0 w/ or w/o Patch A you need
to download new Photon3D runtime from http://developers.qnx.com. The
versions of OS before 6.1.0 is not supported. OpenGL support is very
raw. It is often fail.
versions of OS before 6.1.0 is not supported.
Problems:
1. OpenGL support is very raw. It is often fail. Update function has
not been written yet. Fullscreen mode has not been written yet.
2. Photon has some errors in detecting how much bits per pixel has
videomode, creating images with different color depth.
3. No shared libraries yet. We need manually set flags as
--disable-shared.
Some building issues:
Run configure script without x11 support, e.g.:
./configure --prefix=/usr/local --disable-video-x11
a) for OpenGL support:
./configure --prefix=/usr/local \
--disable-video-x11 \
--disable-shared
a) without OpenGL support:
./configure --prefix=/usr/local \
--disable-video-x11 \
--disable-shared \
--disable-video-opengl
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
