Deploying Qt5 for cross compiling under Linux for Windows

[Trikrista]

How deploy Qt5 for cross compiling under Linux for Windows?
I tried to do so:
@
./configure -xplatform win32-g++ -prefix /opt/qt5win32 -device-option CROSS_COMPILE=i686-w64-mingw32- -nomake examples -nomake tools -continue -qt-sql-sqlite
@

but as a result of this error pops up here:
@
fatal error: windows.h: No such file or directory

Your linux distro?

You must have installed mingw runtime package . E.g. 'mingw-w64-x86-64-dev' or 'mingw-w64-i686-dev' on Ubuntu.

ArchLinux

mingw installed. And there is "windows.h"

[doomer3d]

bq. ArchLinux

You must to install mingw-w64-headers package, who contains win32 includes.

And if you use x86_64 arch, you can use additional repo for install precompiled mingw build of Qt.

@[mingw-w64]
SigLevel = Optional TrustAll
Server = http://downloads.sourceforge.net/project/mingw-w64-archlinux/$arch

mingw-w64-headers installed

I installed mingw-w64-qt5-base-opengl from http://downloads.sourceforge.net/project/mingw-w64-archlinux/$arch

What I must write after CROSS_COMPILE that compiling start?

[Trikrista]

I added path to "include" in qmake.conf.

Now appear new mistakes:

@
