Ubuntu

Am running QTCreator and Ubuntu developer. How to ??

Asked by harrison

I need C++11 support from the g++ but can't find where to add the -std c++11 command. The Ubuntu system is fairly sophisticated and the make file is very evident. That doesn't help me address the compiler to get it to support C++11.
I regularly use code""blocks and am familiar with the C++11 requirements. All I need to know is how to enable the compiler to follow the c++11 guide.

Thanks for previous recommendations on QT 4 and 5. Looks like I can do it with the Ubuntu developer and QT Creator,

It should just take inclusion of -std=gnu++11 when you invoke the compiler. For example:
g++ -std=gnu++11 MyCode.cpp -o MyApp

My previous answer was for direct invocation of g++ in a make file.

I'm not able to see the pro file you reference.

Check out this link:
http://stackoverflow.com/questions/16948382/how-to-enable-c11-in-qt-creator

It suggest two possible solutions to enabling c++11 support in a .pro file:
CONFIG += c++11
for Qt 5

or
QMAKE_CXXFLAGS += -std=c++11 (or QMAKE_CXXFLAGS += -std=c++0x
for Qt 4.8 and gcc/clang.

Sok it works fine! The 'pro' file is the main project file for the project.
Thanks again.
