I think that something is wrong with your Qt5 installation.... can you paste output of these commands?

I hope https://github.com/Kakadu/lablqt/issues/16 is unrelated to this....

It seems this bug is not fixed: https://bugreports.qt-project.org/browse/QTBUG-35256

They recommend to add -I${libdir}/QtWidgets.framework/Versions/5/Headers to .pc file. I don't have Mac, I can't test it or fix it, sorry man.

[akovbovich]

Cflags: -F${libdir} -framework QtWidgets
in /Users/andy/Qt/5.3/clang_64/lib/pkgconfig/Qt5Widgets.pc

does the trick

[Kakadu]

Good. Can I close this?

[akovbovich]

ok

[Kakadu]

I hope I will get some feedback about lablqt from you, Andrey :)
