OpenCv + mac os x + qt creator = strange linking bug?

I\'m trying to build simple OpenCV app using qt creator on Mac Os X 10.9. So i\'ve installed OpenCv and Qt4 using brew:

brew install opencv
brew install qt4
         


        

Answer 1

Ok - finally after 4 days of searching i've solved this problem. Generally solution is simple - just add:

QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.9

to you .pro file. If don't want to add it to every .pro file you can set it "globally" - just set it in this file:

Qt5.2.0/5.2.0-rc1/clang_64/mkspecs/macx-clang/qmake.conf 

More information about this bug/problem:
Qt5.1/Qt5.2 + Mac OS 10.9 (Mavericks) + XCode 5.0.2, Undefined symbols for architecture x86_64

//edit:
This solution only works with CLang, no luck with gcc.
