Subject: Patches for QNX RtP
Here my patch for QNX RtP/Photon for SDL-1.2.
Detailed description of my changes:
SDL/configure.in:
If Photon detected declare define ENABLE_PHOTON.
SDL/src/video/SDL_sysvideo.h:
Added extern to ph_bootstrap.
SDL/src/video/SDL_video.c:
Added ph_bootstrap to bootstrap array.
SDL/src/video/photon/SDL_ph_events.c:
Declare DISABLE_X11 if compiled for Photon.
SDL/src/video/photon/SDL_ph_image.c:
Fixed segment violation on exit. Please update BUGS file.
SDL/src/video/photon/SDL_ph_video.c:
1. Enabling window manager.
2. Added to device capabilities Photon Window Manager functions:
SetCaption and IconifyWindow.
3. Renamed X11_bootstrap to ph_bootstrap.
4. Removed SEGFAULT termination of programs if Photon not available.
SDL/src/video/photon/SDL_ph_wm.c:
1. Declare DISABLE_X11 if compiled for Photon.
2. Added ph_SetCaption and ph_IconifyWindow code. (Thanks to
'phearbear' for iconify window source).
3. Some stubers for other wm functions.
Thanks !

| 11 Returns the address of the GL function \fBproc\fR, or \fBNULL\fR if the function is not found\&. If the GL library is loaded at runtime, with \fI\fBSDL_GL_LoadLibrary\fP\fR, then \fIall\fP GL functions must be retrieved this way\&. Usually this is used to retrieve function pointers to OpenGL extensions\&. | |
