os : mac osx 10.8.3
compiler : gcc4.8
The makefiles generated by the qmake of Qt5.0.2 and Qt5.1.0 have some differents
It will always select the default compiler come with XCode(if I interpret the makefile correctly)
The make file generated by qmake come with Qt5.1.0 beta
####### Compiler, tools and options
CC = /Applications/Xcode.app/Contents/Developer/usr/bin/gcc
CXX = /Applications/Xcode.app/Contents/Developer/usr/bin/g++
.......
LINK = /Applications/Xcode.app/Contents/Developer/usr/bin/g++
####### Output directory
The makefile come with Qt5.0.2
####### Compiler, tools and options
CC = gcc
CXX = g++
.......
LINK = g++
####### Output directory
There are some problems if the compiler switch to clang too
The compiler will always be the default compiler come with XCode
And the version numbers also has some problem
In Qt5.0.2, if I want to use the features of c++11
I simply add these lines in my .pro file
mac{
LIBS += -stdlib=libc++
QMAKE_CXXFLAGS += -stdlib=libc++
QMAKE_CXXFLAGS += -std=c++11
QMAKE_CXXFLAGS += -mmacosx-version-min=10.7
QMAKE_LFLAGS += -mmacosx-version-min=10.7
}
But it would not work with the qmake generated come with Qt5.1.0 beta
Edit :
If I change the .pro to
mac{
CONFIG += c++11
}
The codes could compile with Qt5.1.0, but this do not work for gcc
