[vtkusers] Mac Qt vtk difficulties

[John Biddiscombe]

Dear anyone,

I have built an app on a MAC 10.4.7, (powerpc I believe), but although 
the vtk window appears correctly and I can interact with it and zoom 
etc, when I adjust sliders and text edits on screen in the gui, the vtk 
window does not ever update correctly and in fact when I switch to 
various special displays, I get nonsense out. I tried tweaking the build 
options for the application to use Carbon on/off, use X on/ off, use 
Cocoa on/off, I,ve used the MAC_OSX_BUNDLE option in cmake as well as 
/usr/X11R6/..GL or framework GL, and although the application runs fine, 
its as though opengl is just knackered inside the app and it doesn't 
work properly.

Changing various opengl build options sometimes results in an app which 
bombs out on start with "bus error" - not terribly helpful, but probably 
related to the wrong GL calls being sent somehow (mixed framework GL and 
X11R6 GL linkage perhaps)

Anyway. I am unable to debug the application because this XCode thingy 
seems completely useless and I've given up on it. The same code builds 
and runs fine under linux and windows.

Does anyone have any idea what I'm talking about and what I might try to 
solve the problem? (Note that I must have rebuilt Qt/VTK and the app in 
question several dozen times with various configurations so I'm tending 
to lean towards the conclusion that macs just don't work very well.)

thanks

JB
