This section needs improvements: Please help us to cleanup confusing sections and fix sections which contain a todo cross compiling is still unstable

 

Tip
Note: This page is about KDE 4. It isn't applicable for KDE 3 development.

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 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 CVS

• Create a file Toolchain-mingw32.cmake with this content and place it somewhere i.e. in your home

set(KDE4_DATA_DIR ${KDE4_INSTALL_DIR}/share/apps) set(KDE4_LIB_INSTALL_DIR ${KDE4_INSTALL_DIR}/lib) set(KDE4_INCLUDE_DIR ${KDE4_INSTALL_DIR}/include) set(KDE4_KDECORE_LIBRARY ${KDE4_INSTALL_DIR}/lib/libkdecore.dll.a) set(KDE4_KDE3SUPPORT_LIBRARY ${KDE4_INSTALL_DIR}/lib/libkde3support.dll.a) set(KDE4_KDEUI_LIBRARY ${KDE4_INSTALL_DIR}/lib/libkdeui.dll.a) set(KDE4_KIO_LIBRARY ${KDE4_INSTALL_DIR}/lib/libkio.dll.a) set(KDE4_KDNSSD_LIBRARY ${KDE4_INSTALL_DIR}/lib/libkdnssd.dll.a) set(KDE4_KFILE_LIBRARY ${KDE4_INSTALL_DIR}/lib/libkfile.dll.a) set(KDE4_KHTML_LIBRARY ${KDE4_INSTALL_DIR}/lib/libkhtml.dll.a) set(KDE4_KNEWSTUFF2_LIBRARY ${KDE4_INSTALL_DIR}/lib/libknewstuff2.dll.a) set(KDE4_KNOTIFYCONFIG_LIBRARY ${KDE4_INSTALL_DIR}/lib/libknotifyconfig.dll.a) set(KDE4_KPARTS_LIBRARY ${KDE4_INSTALL_DIR}/lib/libkparts.dll.a) set(KDE4_KTEXTEDITOR_LIBRARY ${KDE4_INSTALL_DIR}/lib/libktexteditor.dll.a) set(KDE4_KUTILS_LIBRARY ${KDE4_INSTALL_DIR}/lib/libkutils.dll.a) set(KDE4_PHONON_LIBRARY ${KDE4_INSTALL_DIR}/lib/libphonon.dll.a) set(KDE4_SOLID_LIBRARY ${KDE4_INSTALL_DIR}/lib/libsolid.dll.a) adjust the values according to your setup

Build kdelibs

svn co svn://anonsvn.kde.org/home/kde/trunk/KDE/kdelibs cd kdelibs mkdir build cd build cmake -DCMAKE_TOOLCHAIN_FILE=~/Toolchain-mingw32.cmake ..

• you have to make a link to your kde4automoc for linux in the bin directory

ln -s /path/to/kde4automoc bin/ ln -s /path/to/kconfig_compiler bin/

• since linux is case sensitive you have to make symbolic links for some headers

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

• 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 t

execute the modified command and continue with the normal building
