How to turn on OpenMP when using Qt creator

问题

If I am building the project from Qt creator using VS 2010 compiler, how do i enable OpenMP (when building from visual studio you just enable the feature) Thanks

回答1:

Try next in your .pro file

in case msvc2010

QMAKE_CXXFLAGS+= -openmp
QMAKE_LFLAGS +=  -openmp

or

QMAKE_CXXFLAGS+= -fopenmp
QMAKE_LFLAGS +=  -fopenmp

in case gcc
