(C++) Example 19: STL only console application, use of '-spec cygwin-g++'

Sure fail attempt at solving How to cross-compile a Qt Creator project from Ubuntu to a windows executable?.

Operating system: Ubuntu 10.04 LTS Lucid Lynx

IDE: Qt Creator 2.0.0

Project type: GUI application

Compiler: G++ 4.4.1

Libraries used:

STL: from GCC, shipped with Qt Creator 2.0.0

Project options:

Unchecked 'Projects -> Build Settings -> General -> Shadow build'
In 'Projects -> Build Settings -> Build steps -> qmake -> Additional arguments' added '-spec cygwin-g++' (without the apostrophs)

Qt project file


#-------------------------------------------------

#

# Project created by QtCreator 2010-09-29T10:39:29

#

#-------------------------------------------------

QT       += core

QT       -= gui

TARGET = CppQtCrossCompileToWindowsExample19

CONFIG   += console

CONFIG   -= app_bundle

TEMPLATE = app

SOURCES += main.cpp

main.cpp


#include <iostream>



int main()

{

  std::cout

    << "I am\n"

    << "* written using Qt Creator under Ubuntu\n"

    << "* tested to compile under Ubuntu\n"

    << "* tested to create a valid Ubuntu binary\n"

    << "* tested to create an invalid Windows executable\n"

    << "  (using -spec win32-g++)\n";

}

Process

In Qt Creator, pressing 'Run' resulted in a working Ubuntu executable.

Copying the source to a Cygwin folder, a make was attempted:


make

Screen output:


/usr/bin/qmake-qt4 -spec /usr/share/qt4/mkspecs/cygwin-g++ -unix CONFIG+=debug -o Makefile CppQtCrossCompileToWindowsExample19.pro

/usr/bin/qmake-qt4: /usr/bin/qmake-qt4: cannot execute binary file

make: *** [Makefile] Error 126

This approach is estimated to be a sure fail.
