From: "Mike Gorchak" Subject: New patches for QNX6 Here my patches for the SDL/QNX: QNXSDL.diff - diff to non-QNX related sources: - updated BUGS file, I think QNX6 is now will be officially supported - configure.in - added shared library support for QNX, and removed dependency between the ALSA and QNX6. - SDL_audio.c - added QNX NTO sound bootstrap insted of ALSA's. - SDL_sysaudio.h - the same. - SDL_nto_audio.c - the same. - SDL_video.c - right now, QNX doesn't offer any method to obtain pointers to the OpenGL functions by function name, so they must be hardcoded in library, otherwise OpenGL will not be supported. - testsprite.c - fixed: do not draw vertical red line if we are in non-double-buffered mode. sdlqnxph.tar.gz - archive of the ./src/video/photon/* . Too many changes in code to make diffs :) : + Added stub for support hide/unhide window event + Added full YUV overlays support. + Added window maximize support. + Added mouse wheel events. + Added support for some specific key codes in Unicode mode (like ESC). + Added more checks to the all memory allocation code. + Added SDL_DOUBLEBUF support in all fullscreen modes. + Added fallback to window mode, if desired fullscreen mode is not supported. + Added stub support for the GL_LoadLibrary and GL_GetProcAddress functions. + Added resizable window support without caption. ! Fixed bug in the Ph_EV_EXPOSE event handler, when rectangles to update is 0 and when width or height of the rectangle is 0. ! Fixed bug in the event handler code. Events has not been passed to the window widget handler. ! Fixed codes for Win keys (Super/Hyper/Menu). ! Fixed memory leak, when deallocation palette. ! Fixed palette emulation code bugs. ! Fixed fullscreen and hwsurface handling. ! Fixed CLOSE button bug. First event was passed to the handler, but second terminated the application. Now all events passed to the application correctly. - Removed all printfs in code, now SDL_SetError used instead of them. - Disabled ToggleFullScreen function. README.QNX - updated README.QNX file. Added much more issues. --HG-- extra : convert_revision : svn%3Ac70aab31-4412-0410-b14c-859654838e24/trunk%40664

=========================================================================
|
|
OpenGL:
|
|
|
|
OpenGL in window mode works well and stable, in fullscreen
|
|
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:
|
|
|
|
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:
|
|
./configure --prefix=/usr/local \
|
|
--disable-video-x11 \
|
|
--disable-shared
|
|
|
|
b) 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
