To close this story for the record: The problem in this case came from 3rd-party Qt's (several of them) that had been installed in /Library/Frameworks and /usr/local. Unfortunately, qt4-mac's build system is very fragile with respect to pre-installed versions of Qt. It even builds different when a previous version of itself is installed than when it is installed for the first time(*). One of those 3rd-party Qt's even installed its executables in /usr/bin, in particular /usr/bin/qmake, and this breaks building of just about anything that build-depends on qt4-mac. (*) I only saw a small difference: When qt4-mac is already installed, the qt4-mac build system puts '-g' on the compiler lines where on a virgin system it puts '-O2'. This comes from the fact that the file /sw/lib/qt4-mac/mkspecs/qconfig.pri is loaded if it exists. -- Martin ------------------------------------------------------------------------------ Lotusphere 2011 Register now for Lotusphere 2011 and learn how to connect the dots, take your collaborative environment to the next level, and enter the era of Social Business. http://p.sf.net/sfu/lotusphere-d2d _______________________________________________ Fink-devel mailing list Fink-devel@lists.sourceforge.net http://news.gmane.org/gmane.os.apple.fink.devel Subscription management: https://lists.sourceforge.net/lists/listinfo/fink-devel
