How to enable C++11 in Qt Creator?
According to this site add
CONFIG += c++11
to your .pro file (see at the bottom of that web page). It requires Qt 5.
The other answers, suggesting
QMAKE_CXXFLAGS += -std=c++11
(or QMAKE_CXXFLAGS += -std=c++0x
)
also work with Qt 4.8 and gcc / clang.
Add this to your .pro file
QMAKE_CXXFLAGS += -std=c++11
or
CONFIG += c++11
As an alternative for handling both cases addressed in Ali's excellent answer, I usually add
# With C++11 support
greaterThan(QT_MAJOR_VERSION, 4){
CONFIG += c++11
} else {
QMAKE_CXXFLAGS += -std=c++0x
}
to my project files. This can be handy when you don't really care much about which Qt version is people using in your team, but you want them to have C++11 enabled in any case.
