Hello World (or 'The Hello World program') is a standard example program to see if your programming environment works. Note that this example code is not standarized, so multiple and similar variants are on the Internet. A more demanding example is Hello Boost, which also tests if the Boost libraries are installed correctly.

The (C++) code of Hello World is as follows:


#include <iostream>



int main()

{

  std::cout << "Hello World\n";

}

Under Cygwin use the following command to produce a makefile:


qmake-qt4

Making the makefile:


make

Results in the screen output:


g++-4  -o CppHelloWorldQtCreatorCygwin.exe main.o    -L/usr/lib/qt4/lib -lQtCore -L/usr/lib/qt4/lib -lz -lm -lgthread-2.0 -lglib-2.0 -lintl -liconv -ldl -lpthread
