Building Qt project for C++11 standard

问题

I am trying to build my Qt project with C++11 standard. I added this flag in the build steps, additional argument option, in the Qt Creator :

-std=c++11

But I got this error while building :

Unknown option -std=c++11

g++ version info : g++ (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3

Any ideas ?

回答1:

Use the qmake project file, add this line: QMAKE_CXXFLAGS += -std=c++11

LE: also 4.6.3 might not support C++11 (as far as i know 4.7 and higher support -std=c++11) so the option for the 0x features implemented might be: QMAKE_CXXFLAGS += -std=c++0x

回答2:

If you are using Qt5, add CONFIG += c++11 to your .pro file, that works on all systems.
