Can't build application on OS X after updating to the latest version of Qt & XCode

I also updated to OS X Sierra. I updated to xcode version 8.0 (and Qt 5.7) and now I'm getting this error when I try to run make after doing a qmake:

"Qt requires C++11 support"
#  error "Qt requires C++11 support"

and other ones like:

unknown type name 'QAtomicOps'
typedef QAtomicOps<T> Ops;

This is odd since I've got CONFIG += c++14 in my .pro file. I tried setting it to c++11, but it didn't work either.

Hi,

That's because Qt 5.7 was built against the 10.11 SDK and the upgrade to Xcode 8 nuked that one and installed 10.12.

As provisorily workaround your can add:

macx {
    QMAKE_MAC_SDK = macosx10.12
}

to your .pro file

This seemed to have fixed itself now. I don't know why :\

Thanks anyways.
