Using Qt Creator C++ 11, nullptr is keyworded?

Question

I\'m using C++11 using Qt Creator.

\"warning: identifier \'nullptr\' is a keyword in C++11 [-Wc++0x-compat]\"
\"error: \'nullptr\' was not declared in this scope         


        

Answer 1

Open your .pro file from inside QtCreator and add this

QMAKE_CXXFLAGS += -std=c++0x

Answer 2

Try adding the below lines to your cpp source code

#ifndef _GXX_NULLPTR_T
#define _GXX_NULLPTR_T
   typedef decltype(nullptr) nullptr_t;
#endif 
/* C++11 */
