add Windows build environment-mingw to qt5.2.1 on ubuntu(AMD64)

another way to do this  http://silmor.de/qtstuff.cross.php
following is my way

Ubuntu Software Center

install gcc-mingw-w64

install gdb-mingw-w64

install gdb-mingw-w64-target

install mingw-qt:
http://pkgs.org/search/?query=mingw32-qt5-+5.2.1&type=name http://pkgs.org/search/?query=mingw64-qt5-+5.2.1&type=name
download all the reference are "Qt5 for Windows build environment"

rpm install(how)

sudo apt-get install alien

sudo alien package.rpm

sudo dpkg -i package.deb

configue in qt5.2.1









there are two warning, cause I need mingw for building lib, I ignored them.  

that's all, make a test, it worked.

by the way, Build 32-bit Qt on 64-bit Ubuntu

one way:

Projects>Build Settings>Build Steps>Qmake>Additional arguments

-spec linux-g++-32

another way:

install qt..32 in the 32 changeroot.
