must construct QApplication before constructing QPaintDevice

[wysota]

http://doc.trolltech.com/latest/deployment-mac.html

Anyway that's not the issue here. There is something wrong with your code.

[dvmorris]

I really don't see anything wrong with it. Will it definitely have the word static in it? The code is way too large to post up here, so I guess I'll just keep looking. I don't understand why it works with the absolute paths to the libraries, but not with the relative paths.

One thing I noticed that this script does that seems strange is in the results of

otool -L

before the script

saying @executable_path seems wrong, but I don't really know enough about it to know whether that's right or not.

[wysota]

No, the object doesn't have to be static. It's enough if it's global. Maybe your Qt installation is somehow broken?

[dvmorris]

it's 4.3 beta, but 4.2.3 had other errors that I couldn't figure out, and I found this post that said someone fixed the same errors I was having by upgrading to 4.3beta, so I did, and it fixed those errors, but gave me new ones.

oh joy. i really appreciate all your help. Changing my app to Qt from fltk has been a rollercoaster ride so far. thanks again,
dave

[wysota]

Try running your script on a dummy application and see if the problem persists. If so, this could mean a somehow invalid Qt installation or a problem with the script. But if it works, then surely the problem lies within your code.

[dvmorris]

I just tried on an example app , the 2dpainting opengl sample, and it did the same error. that's good to know. Now I just need to find a better script. Perhaps it's the order of the frameworks that I'm including that is the problem. I figured QtCore would need to be first...

I will try a different script. Thanks for your help,
dave

[wysota]

The script might be fine. If it's in the wiki then I assume it works for someone. The problem may lie in cooperation between the script and your Qt compilation.

[dvmorris]

I found a different version of a script that does essentially the same thing, but it's a little more robust, and it works perfectly. Here it is:

i believe my problem with the other script was the order of the list of Qt Frameworks to embed. I always put QtCore first, and this script it written to search for the dependencies and include them in that order, and QtCore seems to come up last, and QtXml first. I won't bother trying the other one again, because this one is a better script all around anyways.
