How to enable C++11 in Qt Creator?
(6 answers)
Closed 7 years ago.
I'm using Qt Creator on Ubuntu, and I'd like to use the new C++11 features, however they are not enabled by default.
How can I configure Qt Creator to support the new C++11 features?
You can achieve this by adding:
QMAKE_CXXFLAGS += -std=c++11
to your .pro file.

Recently I have tried to use some Advance c++ functions in CodeBlocks but all the time it throw errors like " according to c++ 98....... ".
If CodeBlocks uses an old version of c++ can I update it to c++11 or c++14.

Compilation error with "for each" loop in C++ VS2010
(6 answers)
Closed 7 years ago.
I'm trying to compile my old Qt project on another system: Windows XP, Qt5, msvc 2010.
I used c++11 auto in my project, there is a line CONFIG += c++11 in the pro file.
for(auto e : mapTerm->keys())
{
mapTerm->insert(e, attrib.value(e).toString());
}
Now it cannot recognize the auto loop and gives me syntax errors.
You'll need to ensure that you are using the propper C++ compiler and that it is C++11+.
If you are using msvc and are using the correct version then this should be a built in feature.
