Qt Creator 2.1.0 and Qt 4.7.2 on Mac OS X 10.6.6

[agarny]

Hi,

I was wondering whether anyone had tried the latest Qt Creator 2.1.0 and Qt 4.7.2 on Mac OS X 10.6.6 from the recently released Qt SDK 1.1 Beta (though it has beta in its name, I understand that both Qt Creator 2.1.0 and Qt 4.7.2 are final release versions)? I indeed seem to be having to get things to work properly.

I reinstalled Mac OS X on my MacBook Air yesterday, and I have just reinstalled Xcode and now Qt SDK 1.1 Beta. Now, when starting Qt Creator, I get the following message:

GLSLEditor
Could not resolve dependency 'Core(2.1.81)'
Could not resolve dependency 'TextEditor(2.1.81)'
Could not resolve dependency 'ProjectExplorer(2.1.81)'

Could not resolve dependency 'ProjectExplorer(2.1.81)'
Could not resolve dependency 'Locator(2.1.81)'
Could not resolve dependency 'CppTools(2.1.81)'

Also, if I try to build my application from the command line (using CMake), everything goes apparently smoothly until the very end when I get the following messages:

ERROR: file copy failed from "/Developer/QtSDK/Desktop/Qt/472/gcc/lib/QtGui.framework/Resources/qt_menu.nib/classes.nib"
ERROR: to "OpenCOR.app/Contents/Frameworks/QtGui.framework/Resources/qt_menu.nib/classes.nib"

ERROR: to "OpenCOR.app/Contents/Frameworks/QtGui.framework/Resources/qt_menu.nib/keyedobjects.nib"

From there, if I try to run my application, I get the following:

One of the two will be used. Which one is undefined.

On Mac OS X, you might be loading two sets of Qt binaries into the same process. Check that all plugins are compiled against the right Qt binaries. Export DYLD_PRINT_LIBRARIES=1 and check that only one set of binaries are being loaded.

I guess it's worth pointing out that it used to work all fine with Qt Creator 2.0.1 and Qt 4.7.0. Also, using Qt Creator 2.1.0 and Qt 4.7.2, everything is fine on Windows 7 and Linux Mint. So, I am starting to wonder what might be wrong on Mac OS X...

Cheers, Alan.

Regarding the errors I get during compilation, I have found out that it's as a result of using macdeployqt... (!?) Also, the crazy thing is that the files are actually being properly copied... (!?)

I have the same problem. I uninstall my owl qt sdk (with qt creator 4.7) & i install the beta of qt 1.1 but i have exactly the same problems. Ah! and photoshop doesn't integrate with the 'export qml' option. I'm on MAC OS X 10.6.6

I Solve the problem going to maintance mode (on QtSDK folder, on the root) and updating the QT Creator IDE

But i can't get the integration with Photoshop =S

Yes, indeed the Qt Creator problem goes away after the update. I, however, still have the problem with macdeployqt, as further discussed in this thread. In fact, it seems like it might be a bug which I was asked to file, and which I did here.

[wingsandsky]

Oh! i don't know about that issue. I already get working the integration with Photoshop

For your information, I have personally ditched Qt SDK Beta 1.1. As I have been told here, there may be something wrong with the packaging of Qt SDK 1.1 which after all is still beta even though both Qt and Qt Creator are not.

Anyway, the point is that you might want to uninstall all of Qt SDK 1.1 and individually install Qt 4.7.2 and Qt Creator 2.1.0. This is what I ended up doing and, now, everything works as expected.
