Qt 5.2 Mac 10.10.1 Undefined symbols for x86_64 architecture

Question

I am working on an opencv, Qt application on my Mac, however compiling gives me an error, for example

Undefined symbols for architecture x86_64

I based the solution here, Qt5.1 / Qt5.2 + Mac OS 10.9 (Mavericks) + Xcode 5.0.2, Undefined characters for x86_64 architecture

what i changed / usr / local / Cellar / qt 5 / 5.3.2 / mkspecs / macx-clang / qmake.conf

from

QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.6

to

QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.9

after cleaning the project, it doesn’t work, I wonder what other change?

///// update ////

I previously found that my default set used g ++ as a compiler, and now I changed it to clang as the default compiler, you can see my configuration here https://www.dropbox.com/s/93viwvf1a70s347/Screenshot%202015 -02-13% 2002.43.23.png? Dl = 0
