Indeed. Let's hope so.

OK. I've just set these in cmake and am building again.

I did a
make confclean
./configure -prefix /Users/biddisco/qt-4.1.4
and left everything else alone. I'm hoping the default options will do 
for everything else

Ok.

No the app runs fine. All is well, it is only the openGL that does not 
work properly. I have seen a message that says that Qt is expecting the 
begin to be called before the paintdevice is ready etc etc. I've not 
seen that recently, I think I fixed whatever was causing it.

4.1.4

Sorry. I have several options in my code and one is to use a custom 
mapper I've made for VTK that uses Shading language GL2.0 stuff. When I 
enable it, I get rubbish out from the display and the image bears no 
resemblance to what it should be.

OK. That is set in cmake correctly

they work fine in windows and under Linux, suse 10 and suse 9

I expect they are lovely people, but ideally I'd like to ssh into the 
mac, run make, collect a binary and give it to people who ask for it 
without ever touching the machine again. I have not had a happy mac 
experience so far.

OK. That sounds like it may be useful. I don't really believe there's 
anything wrong with XCode, but I'm fed up with it now. I'll try again 
next week when my patience has recoevered

Thank you for your suggestions. I'm doing it by the book now using the 
options you have suggested above. I usualy build everything static, but 
am doing dynamic this time in the hope it helps.

cheers
