QT       += core

QT       -= gui

TARGET = CppQtCrosscompileToWindowsExample1

CONFIG   += console

CONFIG   -= app_bundle

TEMPLATE = app

SOURCES += main.cpp

main.cpp


#include <iostream>



int main()

{

  std::cout <<

    "I am developed under Unbuntu, "

    "and I will run under Windows\n";

}

Process

In an Ubuntu terminal, go to the folder containing main.cpp. Then type the following:


i586-mingw32msvc-g++ -o MyWin.exe main.cpp

This successfully creates a Windows executable called MyWin.exe. I have confirmed this to work on my old Windows computer.

You can install mingw this way:



sudo apt-get install mingw32



and then you can simply compile using i586-mingw32msvc-gcc instead of gcc:



i586-mingw32msvc-gcc -o test.exe test.c



You can also use i586-mingw32msvc-g++ and related tools.



If you use any libraries in your program, you will either need to crosscompile them too or just download the precompiled binaries for windows.
