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.
On gentoo, you need to do the following: "emerge crossdev; crossdev mingw32".
You can install these dependencies(aspell, boost, dbus, qca etc..) from windows with the kdewin installer or manually download them from sourceforge mirrors
You also need to have Qt4 and KDE4 already installed on linux, to use moc/uic/kde4automoc etc...
To cross compile KDE you need CMake >= 2.5, you can get the last version from CVS
set(KDE_PREFIX /windows/kde4)
set(KDE4_SRC_DIR /home/kdeuser/kde/src)
SET(CMAKE_SYSTEM_NAME Windows)
SET(CMAKE_C_COMPILER i586-mingw32msvc-gcc) SET(CMAKE_CXX_COMPILER i586-mingw32msvc-g++)
SET(CMAKE_FIND_ROOT_PATH /usr/i586-mingw32msvc ${KDE_PREFIX} )
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER) set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY) set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
set(QT_BINARY_DIR ${KDE4_SRC_DIR}/qt-copy/bin) set(QT_LIBRARY_DIR ${KDE_PREFIX}/lib) set(QT_QTCORE_LIBRARY ${KDE_PREFIX}/lib/libQtCore4.a) set(QT_QTCORE_INCLUDE_DIR ${KDE_PREFIX}/include/QtCore) set(QT_MKSPECS_DIR ${KDE_PREFIX}/mkspecs) set(QT_MOC_EXECUTABLE ${QT_BINARY_DIR}/moc) set(QT_QMAKE_EXECUTABLE ${QT_BINARY_DIR}/qmake) set(QT_UIC_EXECUTABLE ${QT_BINARY_DIR}/uic)
set(KDE_PREFIX /windows/kde4)

set(KDE4_DATA_DIR ${KDE_PREFIX}/share/apps CACHE PATH "points to the apps directory of installed kdelibs")
set(KDEWIN_DIR ${KDE_PREFIX} CACHE PATH "what is it ?")
set(WITH_AVAHI OFF CACHE BOOL "Disabled") set(WITH_DNSSD OFF CACHE BOOL "Disabled") set(WITH_ENCHANT OFF CACHE BOOL "Disabled") set(WITH_FAM OFF CACHE BOOL "Disabled") set(WITH_GSSAPI OFF CACHE BOOL "Disabled") set(WITH_HSPELL OFF CACHE BOOL "Disabled") set(WITH_OpenEXR OFF CACHE BOOL "Disabled")

adjust the values according to your setup
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 and kconfig_compiler for linux in the bin directory <syntaxhighlight lang="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 <syntaxhighlight lang="bash"> cd /windows/kde4/include ln -s soprano Soprano </code> * You will get an error in klauncher.moc about slotKDEInitData so go into kinit and do something like this(you need wine) <syntaxhighlight lang="bash"> rm *.moc ../bin/kde4automoc.exe /home/kdeuser/kde/src/KDE/kdelibs/build/kinit/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 :) <syntaxhighlight lang="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 -C ~/mingw32-kdelibs.cmake .. make make install </code> ==Build kdebase== This is easy :) <syntaxhighlight lang="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 -C ~/mingw32-kdelibs.cmake .. make make install </code> == Icecream == One of the joys of cross-compiling is the possibility to use an icecream cluster to speed up compilation. For Debian Etch, you can get an icecream environment from here: ftp://ftp.kdab.net/pub/gpg4win/devtools/debian-etch-mingw32-icecream-env.tar.gz (If you want to create your own environment: icecc-create-env does a good job except that it packages the wrong as. /usr/bin/i586-mingw32msvc-as is needed) The bin/ dir with symlinks from i586-mingw32msvc-* to /usr/bin/icecc: ftp://ftp.kdab.net/pub/gpg4win/devtools/icecc-mingw-bin.tar.bz2 Untar icecc-mingw-bin.tar.bz2 to icecc-mingw-bin Then set the following environment variables: <syntaxhighlight lang="bash"> export PATH=/path/to/icecc-mingw-bin/bin:$PATH export ICECC_CC=i586-mingw32msvc-gcc export ICECC_CXX=i586-mingw32msvc-g++ export ICECC_VERSION=i686:/path/to/debian-etch-mingw32-icecream-env.tar.gz,x86_64:/path/to/debian-etch-mingw32-icecream-env.tar.gz </code> (Re-)run cmake and have fun.
