How to use pthread on Qt Creator

Question

I want to execute a following code.

#include 
#include 

void output() {
    std::cout << \"Hello World\" << std::e         


        

Answer 1

You also need to link against -pthread. If you use g++ main.cpp -std=c++0x -pthread you are doing all that in one step, so it works correctly. To make Qt do the correct things, add the following to your project file:

QMAKE_CXXFLAGS += -std=c++0x -pthread 
LIBS += -pthread

Answer 2

This works for me:

TEMPLATE = app
TARGET = 
DEPENDPATH += .
INCLUDEPATH += .

# Input
SOURCES += test.cpp

QMAKE_CXXFLAGS += -std=gnu++0x -pthread
QMAKE_CFLAGS += -std=gnu++0x -pthread

Your example compiles and executes correctly with the above .pro file on my system.

Try save your example as test.cpp, and the above as project.pro in same directory. Then type:

$ qmake
$ make
$ ./project
Hello World
