Qt Application + Mac Os 10.9 Maverick
-
Hi guys,
I have a question similar to "this one":http://qt-project.org/forums/viewthread/32495/, but it is a bit different. The problem is that I have an application written based on Qt 5.0.2, and it was perfectly compiling with Qt Creator 2.7.0 on Mac Os Mountain Lion. But a couple of days ago (who knows why) I have updated my Lion OS to the new OS Maverick, and it crashed my application completely. I could not even open Qt creator 2.7.0. I reinstalled Qt Framework to the Qt 5.2.0 with Qt Creator 2.8.8. The Qt Creator works, but when compiling my app I get a bunch of errors like
error: variable has incomplete type 'class Q_WIDGETS_EXPORT'
class Q_WIDGETS_EXPORT QSizePolicy
^If I change the path to Qt 5.0.2 still using Qt Creator 2.8.8, then I can compile without errors but, once my application is opened, it crashes with error similar to that one with Qt Creator 2.7.0 - "App quit unexpectedly."
Please, if you know how to fix this stupid problem, let me know. I urgently need my application to work.
P. S. I do not have any dependencies on the libraries based on Qt 4.
P. P. S. The same errors appear if I compile with Qt Creator 2.8.1 and Qt 5.1.1.Thanks a lot in advance!

I have a similar problem..
My qt app runs ONCE after I unpack it on my brand new OSX 10.9 Mavericks, then launching it a second time, it crashes.I found out.. when I go into super user mode, "sudo" it runs fine.
Is there a way to allow all users to run the app by default, any settings, when I package the app? Or is this a Mavericks-sided problem?

Hi,
What version of Qt are you using ? What does the report say ?
For Mavericks, you should use Qt 5.2, Apple did a lot of little changes that brought some problems

Hi, thanks..
I've built and deploy-enabled my app on a different system (OSX 10.6.8) using Qt 5.1.1 with clang compiler and macdeployqt from that same Qt installation.
So you're saying, I should rebuild the app with Qt 5.2 beta version - which could solve the problems?
This one I assume..
http://download.qt-project.org/development_releases/qt/5.2/5.2.0-beta1/I'll try and report back.

I tried to build my app with both Qt 5.1 and Qt 5.2, and it did not help me - the same error. Your app compiles at least once, mine does not compile at all, and I have no idea how to fix it. If you guys have any idea how to get rid of this, please let me know:
error: variable has incomplete type ‘class Q_WIDGETS_EXPORT’
class Q_WIDGETS_EXPORT QSizePolicy ^This is an internal error from Qt headers, not my headers.
