Crash after macdeployqt

Hi all,

i have a little problem.
I have created a little application that i now want to deploy for mac os x. So i compiled it on my mac and everything works fine. The application runs stable, like on windows.

Now to deploy the application i used the macdeployqt tool that comes with the qt sdk. The strange thing about the whole thing, after i ran the deploy tool the application crashes on my mac, but if i test it on a "non developer" mac, with no qt installed, the application works fine!

Like i understand the error message, the Qt libs in my case QtCore, QtGui and QtNetwork are loaded twice. The one from the app package and the one from the system.

Little cut out of the error report:

As you can see in the address space the crash happens because the application first uses the QtGui lib of the application package but then tries to call the system wide QtGui lib.

Is there any solution for the problem?

Thanks,
Stefan

Use otool -L on the binary within the bundle and see to which libraries you actually link. I think your executable links agains the libraries in the bundle but the libraries themself link against their friends in the system. After doing this, we can dig further for a solution.
