Qt creator platform codegen flags

Seems Qt creator "platform codegen flags" does not take effect (Tools->Options...->Build&Run->Compillers). Mentioned there "-std=c++11" flag however it was not added to Makefile. Also added g++-5 there - also no effect: CXX = g++ CXXFLAGS = -pipe -g -Wall -W $(DEFINES)

Should be: CXX = g++-5 CXXFLAGS = -pipe -g -Wall -W $(DEFINES) -std=c++11

How to correctly add flags there.

Solution

  • If you use qmake as build system, then you can add flags to the compiler via QMAKE_CXXFLAGS variable in your .pro file:

    QMAKE_CXXFLAGS += -std=c++11

    And specify a compiler for C++:

    QMAKE_CXX = g++-5

    Also you can pass additional arguments to make in the "Projects" tab.

    Don't know what is "platform codegen flags" though.
