qt4-mac+debug - Problems with Debug libs in Qt

Tue Mar 12 12:14:29 PDT 2013

Hi Michael,

thanks for your immediate response! By reminding me of otool - once again - I was able to dig much further! :)

Here is what I get for that (sorry a little lengthy, but there is more of my text at the bottom of this):

The last two dyld:-lines show that also the non-debug versions get linked…
That seems to be the problem!!!!!!!

The app itself isn't linked directly to non-debug:
---
$ otool -L ../RackGUI-build-Desktop_Version_4-Debug/RackGUI.app/Contents/MacOS/RackGUI ../RackGUI-build-Desktop_Version_4-Debug/RackGUI.app/Contents/MacOS/RackGUI:
	/opt/macports-test/Library/Frameworks/QtGui.framework/Versions/4/QtGui_debug (compatibility version 4.8.0, current version 4.8.4)
	/opt/macports-test/Library/Frameworks/QtCore.framework/Versions/4/QtCore_debug (compatibility version 4.8.0, current version 4.8.4)
	/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.11)
---

So, the problem must occur somewhere else then…

How can I find out which library actually pulls in non-debug libs, although I am having a debug build here?
Could it be that libqtaccessiblewidgets.dylib is the culprit?
---
$ otool -L /opt/macports-test/share/qt4/plugins/accessible/libqtaccessiblewidgets.dylib
/opt/macports-test/share/qt4/plugins/accessible/libqtaccessiblewidgets.dylib:
	libqtaccessiblewidgets.dylib (compatibility version 0.0.0, current version 0.0.0)
	/opt/macports-test/Library/Frameworks/QtGui.framework/Versions/4/QtGui (compatibility version 4.8.0, current version 4.8.4)
	/opt/macports-test/Library/Frameworks/QtCore.framework/Versions/4/QtCore (compatibility version 4.8.0, current version 4.8.4)
	/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.0)
---
YES, that's it!!!!!!

And this happens although I have qt4-mac's debug variant installed:
---
$ port installed qt4-mac
The following ports are currently installed:
  qt4-mac @4.8.4_6+debug (active)
---

So, the question is now whether Qt-Creators build environment made a mistake. How can I analyze this further, Michael?

> I also tend to believe that drop-down menu problems are more related to Qt-specific issues, and nothing that I can really do anything about without a patch.  
OK.

> Have you tried QtCreator 2.7RC yet?  
No, but I have tried just now 2.6.1 installed through MacPorts.

> That might fix the issue, too.
Hmmm, looks like I could give that a try, but I am afraid this is not caused by the creator itself anyway.

>  You could also try reverting back to qt4-mac 4.8.0, or 4.7.4 to see if that changes anything -- of course you might need to relink QtCreator, but you could do this.  Do you know how to do this using MacPorts?  It's not difficult; I'll pass on the wisdom if you want me to. - MLD
Well, actually I know how to go back in time, but I don't want to do this, since I prefer to stay at the bleeding edge. ;-)
