I am using OpenMP in my Visual Studio projects and currently thinking very seriously in changing to QT creator. (Doesn\'t Visual Studio suck?,I expect much more from Microsoft)<
Does QT creator support OpenMP?
As someone else mentioned, it's not Qt itself that support OpenMP but the compiler.
What should I do to enable it?
If you have installed a recent Qt 4.6.x SDK (hint: latest QtCreator 1.3 is included), it comes with MinGW 4.4 which has OpenMP support built-in.
Do I need to do something special?
Edit your project .pro file and add the following lines to pass the OpenMP flags to the compiler :
QMAKE_CXXFLAGS += -fopenmp
LIBS += -fopenmp
Enjoy!
