在Mac命令行下编译Qt5 helloworld

#include <QtWidgets/QApplication>
#include <QtWidgets/QLabel>
int main(int argc, char *argv[])
{
     QApplication app(argc, argv);
     QLabel label("hello world");
     label.show();
     return app.exec();
}

采用如下命令进行编译：

g++ -I/usr/local/opt/qt/include -std=c++11 -F/usr/local/opt/qt/lib 
-framework QtCore -framework QtWidgets -o helloworld main.cpp
