QT Creator adds -Xarch

Question

I was using the QT Creator with an old GCC, now i updated to the 4.8 version. But the QT Creator adds a -Xarch_x86_64 option, the GCC 4.8 tells me

g++: error

Another way to resolve this problem is to edit the file for the compiler configuration for the specific qt version and the specific target build.

See this post.

In my case this conf file is:

/usr/local/Qt4.8/mkspecs/common/g++-macx.conf

And the changes are:

QMAKE_CFLAGS_X86_64 += -Xarch_x86_64 -mmacosx-version-min=10.5
QMAKE_CFLAGS_PPC_64 += -Xarch_ppc64 -mmacosx-version-min=10.5

to

QMAKE_CFLAGS_X86_64 += -Xarch_x86_64 -mmacosx-version-min=10.7
QMAKE_CFLAGS_PPC_64 += -Xarch_ppc64 -mmacosx-version-min=10.7

Please see the linked post from natoferreira in the Q&A of opencv website. Also this post mention this file.

Please add a comment if you know other information about this configuration file for Qt and GCC.
