Hi,
To do some followup testing, I created another build, this time with -no-qt3support

./configure -opensource -platform macx-g++ -shared -release -arch i386 -opengl -cocoa -qt-gif -no-qt3support -nomake examples -nomake demos -prefix /Developer/Applications/Qt-4.7

The resulting QtGui.pc still has a reference to -framework Carbon as shown below

Libs.private: -L/Developer/Applications/Qt-4.7/lib -F/Developer/Applications/Qt-4.7/lib -framework QtCore -L/Developer/Applications/Qt-4.7/lib -framework Carbon -lz -framework AppKit -lz -lz

This is clearly a bug.

How can I fix this issue? If I can have a fix, I can apply it and continue building QwtPlot3d with my app, with Cocoa only support.

Best regards,

Elvis Dowson
