The versions -of OS before 6.1.0 are not supported. +mode too, but fullscreen mode has not been heavily tested yet. + If you have QNX RtP version 6.1.0 and above you must download +new Photon3D runtime from http://developers.qnx.com or install it +from public repository or from public CD, available with QNX. The +versions of OS before 6.1.0 are not supported. + 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 to +test OpenGL - maybe it work or maybe not :)). If you want accele- +ration - you may remove some line in source code: find the file +SDL_ph_video.c and remove the following + + OGLAttrib[OGLargc++]=PHOGL_ATTRIB_FORCE_SW; + +line in the ph_SetupOpenGLContext() function or change argument +to the PHOGL_ATTRIB_FORCE_HW or PHOGL_ATTRIB_FAVOR_HW. + +========================================================================= +Wheel and multibutton mouses: + + Photon emitting keyboard events (key up and down) when moved +mouse wheel. But key_scan field appears valid according to flags, +and it contain zero. It is base method of detecting mouse wheel +events under photon. It looks like a hack, but it works for me :) +on different PC configurations. + +I'm tested it on: + +1. Genius Optical NetScroll/+ (1 wheel) +2. A4Tech Optical GreatEye WheelMouse, model: WOP-35. (2 wheels + + 2 additional buttons). Wheel for vertical scrolling works as + usual, but second wheel for horizontal scrolling emitting two + consequented events up or down, so it can provide more fast + scrolling then the first wheel. Additional buttons doesn't + emitting any events, but its look like handled by photon in + unusual way - like click to front, but works not with any win- + dow, looks like bug-o-feature :). + +========================================================================= +CDROM handling issues: -Problems: -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 - code). -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- - de. + Access to CDROM can be provided only with 'root' previleges. +I can't do anything with this fact. /dev/cd0 have the brw------- +flags and root:root rights. + +========================================================================= +Video Overlays: + Overlays can flickering during the window movement, resizing, +etc. It happens because photon driver updates the real window +contents behind the overlay, then draws the temporary chroma key +color over window contents. It can be done without the chroma key +using but it cause overlay will be always on top. So flickering +during the movement much better in that case. + Double buffering code temporary disabled in the photon driver +code, beacuse on my GF2-MX it cause accidently buffer switch, +which going to the old frame showing. S3 Savage3D have the same +problem, but ATI Rage 128 has not this problem. I think it can be +fixed later. Current code works very fine, so maybe double buffe- +ring is not needed right now. + Something strange appears when you tried to move window with +overlay beyond the left border of the screen. Overlay trying to +stay at position x=0, but when tried to move it a bit more it +jumps at posituin x=-60. Really strange, looks like overlay +doesn't love the negotive coordinates. + +========================================================================= +Shared library building: + + Shared library can be built, but before running autogen.sh +script you need manually delete the libtool m4 stuff from +the acinclude.m4 file (it comes after ESD detection code up to +end of the file). Because libtool stuff in the acinclude.m4 file +very old and doesn't know anything about the QNX. Just remove it +and run autogen.sh script. + +========================================================================= Some building issues: + Feel free to not pass --disable-shared option to configure, +if you read comment above about 'Shared library building'. Other- +wise this option is strongly recomended, because the sdl-config +script will be unfunctional. + Run configure script without x11 support, e.g.: a) for OpenGL support: @@ -42,3 +109,4 @@ --with-sdl-exec-prefix=/usr/local \ --prefix=/usr/local --without-x +
