==Basic tools==
===MinGw===
Install mingw for linux, on debian the packages are called mingw32, mingw32-binutils, mingw32-runtime, you need to install mingw32 with gcc/g++ 3 and not 4 since that doesn't work with kdelibs, debian testing/unstable has gcc 4 so i've installed mingw32 package from ubuntu repository
===Qt4 Kdesupport and dependencies===
You can install these dependencies(aspell, boost, dbus, qca etc..) from windows with the kdewin installer or manually download them from [http://sourceforge.net/project/showfiles.php?group_id=214730 sourceforge mirrors]
===Qt4 and KDE4 for linux===
You also need to have Qt4 and KDE4 already installed on linux, to use moc/uic/kde4automoc etc...
===Cmake===
To cross compile kde you need cmake >= 2.5, you can get the last version from [http://cmake.org/HTML/Download.html#cvs CVS]

adjust the values according to your setup
 
==Build kdelibs==
<code bash>
svn co svn://anonsvn.kde.org/home/kde/trunk/KDE/kdelibs
cd kdelibs
mkdir build
cd build
cmake -DCMAKE_TOOLCHAIN_FILE=~/Toolchain-mingw32.cmake  ..
</code>
* you have to make a link to your kde4automoc for linux in the bin directory
<code bash>
ln -s /path/to/kde4automoc bin/
ln -s /path/to/kconfig_compiler bin/
</code>
* since linux is case sensitive you have to make symbolic links for some headers
<code bash>
cd /usr/i586-mingw32msvc/include
ln -s userenv.h Userenv.h
ln -s windows.h Windows.h
cd /windows/kde4/include
ln -s soprano Soprano
</code>
* You will get a linker error on kjsembed so from the build directory cd into kjsembed/kjsembed and make VERBOSE=1 2>/dev/null
copy the last command i.e.
/usr/bin/i586-mingw32msvc-g++    -Wl,--export-all-symbols -Wl,--disable-auto-import -shared -o ../../bin/libkjsembed.dll -Wl,--out-implib,../../bin/libkjsembed.dll.a -Wl,--major-image-version,4,--minor-image-version,1 CMakeFiles/kjsembed.dir/kjsembed_automoc.cpp.obj CMakeFiles/kjsembed.dir/kjseglobal.cpp.obj CMakeFiles/kjsembed.dir/binding_support.cpp.obj CMakeFiles/kjsembed.dir/static_binding.cpp.obj CMakeFiles/kjsembed.dir/variant_binding.cpp.obj CMakeFiles/kjsembed.dir/object_binding.cpp.obj CMakeFiles/kjsembed.dir/builtins.cpp.obj CMakeFiles/kjsembed.dir/fileio.cpp.obj CMakeFiles/kjsembed.dir/jseventmapper.cpp.obj CMakeFiles/kjsembed.dir/eventproxy.cpp.obj CMakeFiles/kjsembed.dir/slotproxy.cpp.obj CMakeFiles/kjsembed.dir/jseventutils.cpp.obj CMakeFiles/kjsembed.dir/qobject_binding.cpp.obj CMakeFiles/kjsembed.dir/kjsembed.cpp.obj CMakeFiles/kjsembed.dir/value_binding.cpp.obj CMakeFiles/kjsembed.dir/iosupport.cpp.obj CMakeFiles/kjsembed.dir/qwidget_binding.cpp.obj CMakeFiles/kjsembed.dir/qaction_binding.cpp.obj CMakeFiles/kjsembed.dir/qlayout_binding.cpp.obj CMakeFiles/kjsembed.dir/qpainter_binding.cpp.obj CMakeFiles/kjsembed.dir/settings.cpp.obj CMakeFiles/kjsembed.dir/svg_binding.cpp.obj CMakeFiles/kjsembed.dir/filedialog_binding.cpp.obj CMakeFiles/kjsembed.dir/application.cpp.obj CMakeFiles/kjsembed.dir/color.cpp.obj CMakeFiles/kjsembed.dir/dom.cpp.obj CMakeFiles/kjsembed.dir/font.cpp.obj CMakeFiles/kjsembed.dir/image.cpp.obj CMakeFiles/kjsembed.dir/pen.cpp.obj CMakeFiles/kjsembed.dir/pixmap.cpp.obj CMakeFiles/kjsembed.dir/point.cpp.obj CMakeFiles/kjsembed.dir/rect.cpp.obj CMakeFiles/kjsembed.dir/size.cpp.obj CMakeFiles/kjsembed.dir/url.cpp.obj CMakeFiles/kjsembed.dir/bind_qlcdnumber.cpp.obj CMakeFiles/kjsembed.dir/bind_qtimer.cpp.obj CMakeFiles/kjsembed.dir/brush.cpp.obj CMakeFiles/kjsembed.dir/QBrush_bind.cpp.obj CMakeFiles/kjsembed.dir/quiloader_binding.cpp.obj -L/windows/kde4/bin -L/windows/kde4/lib ../../bin/libkdecore.dll.a /windows/kde4/lib/libQtCore4.a /windows/kde4/lib/libQtUiTools.a /windows/kde4/lib/libQtGui4.a /windows/kde4/lib/libQtSvg4.a ../../bin/libkjs.dll.a /windows/kde4/lib/libQtNetwork4.a /windows/kde4/lib/libQtDBus4.a /windows/kde4/lib/libz.dll.a /windows/kde4/lib/libkdewin32.dll.a -luser32 -lshell32 -lws2_32 -lnetapi32 -luserenv /windows/kde4/lib/libQtXml4.a /windows/kde4/bin/bzip2.dll /windows/kde4/lib/libintl.dll.a /windows/kde4/bin/libpcre.dll /windows/kde4/bin/libpcreposix.dll
 
you need to remove
/windows/kde4/lib/libQtCore4.a /windows/kde4/lib/libQtUiTools.a /windows/kde4/lib/libQtGui4.a /windows/kde4/lib/libQtSvg4.a /windows/kde4/lib/libQtNetwork4.a /windows/kde4/lib/libQtDBus4.a /windows/kde4/lib/libQtXml4.a
from this command and add
-lQtCore4 -lQtUiTools -lQtGui4 -lQtSvg4 -lQtNetwork4 -lQtDBus4 -lQtXml4
execute the modified command and continue with the normal building
 
* You will get another error in klauncher.moc about slotKDEInitData so go into kinit and do something like this(you need wine)
<code bash>
make clean
rm *.moc
../bin/kde4automoc.exe /home/kdeuser/kde/src/KDE/kdelibs/build/kinit/kdeinit_klauncher_automoc.cpp /home/kdeuser/kde/src/KDE/kdelibs/kinit /home/kdeuser/kde/src/KDE/kdelibs/build/kinit /windows/kde4/bin/moc.exe
</code>
and then do make as usual
 
* Another error in kdewidgets because wine doesn't find some dll to run makekdewidgets.exe so either run the linux version manually like this
makekdewidgets -o /home/kdeuser/kde/src/KDE/kdelibs/build/kdewidgets/kdewidgets.cpp /home/kdeuser/kde/src/KDE/kdelibs/kdewidgets/kde.widgets
or symlink those missing library in your wine system32 folder(i haven't tested it but it should work)
 
==Build kdepimlibs==
This is easy :)
<code bash>
svn co svn://anonsvn.kde.org/home/kde/trunk/KDE/kdepimlibs
cd kdepimlibs
mkdir build
cd build
cmake -DCMAKE_TOOLCHAIN_FILE=~/Toolchain-mingw32.cmake  ..
make
make install
</code>
==Build kdebase==
This is easy :)
<code bash>
svn co svn://anonsvn.kde.org/home/kde/trunk/KDE/kdebase
cd kdebase
mkdir build
cd build
cmake -DCMAKE_TOOLCHAIN_FILE=~/Toolchain-mingw32.cmake  ..
