Projects/KDE on Windows/Compiling Applications

Compiling (third-party) applications for KDE on Windows

This page gives instructions on how to build a KDE based application on Windows. It is mostly targeted at developers / power users of KDE applications which are not regularly included in the KDE on Windows installer. This typically applies to third-party applications, but may be of interest to developers of applications inside the KDE software collection / repository as well.

Note however that in many cases using emerge may be a better alternative, esp. if you want to compile your application against the most recent development version of KDE.


  • Naturally, you need an installation of KDE. Use the KDE on Windows installer to install it.
    • On the third page of the installer, select "Package Manager mode", and be sure to pick the compiler that you intend to use. For simplicity, we will assume you use "MinGW4" (32bit).
    • Be sure to install at least the following packages:
      • cmake (Bin)
      • automoc (Bin)
      • kdebase-runtime-mingw4 (Bin)
      • kdebase-workspace-mingw4 (Bin)
      • kdelibs-mingw4 (Bin, Devel)
      • qt-mingw4 (Bin, Devel)
      • phonon-mingw4 (Bin, Devel)
      • soprano-mingw4 (Bin, Devel)
      • Many more needed dependencies will be included automatically
      • Depending on the application you may need to select additional packages, such as e.g. kdepimlibs (Bin, Devel)
    • NOTE Package "automoc" is not included in the 4.4.4-release, at the time of this writing. You can download the 4.3.2-version, and unpack this to you KDE installation root.
  • Install MinGW4. These days MinGW has a relatively simple installer. See [1] for further info. Be sure to install at least the C++ compiler.
  • You need perl. E.g. from [2] . TODO: check whether perl is available from the installer.

Further preparations

  • Hack for KDE 4.4.4: You will need to edit the file KDEDIR\share\apps\cmake\modules\KDELibs4LibraryTargets-release.cmake around lines 20 and 36) and replace "U:" by "${_IMPORT_PREFIX}".


Well give the procedure in the form of a .bat file, below. Run this from your source folder.

REM modify these lines to match according to your installation: SET KDEPREFIX=C:\KDE SET MINGWPREFIX=C:\mingw SET PERLPREFIX=C:\Perl

REM you may want to add some cmake flags: SET ADD_CMAKE_FLAGS=-DCMAKE_BUILD_TYPE=Release REM this addition appears to be needed for KDE 4.4.x with MinGW 4.5.x: SET ADD_CMAKE_FLAGS=%ADD_CMAKE_FLAGS% -DCMAKE_EXE_LINKER_FLAGS="--static-libc++ --static-libcc"

REM -------------------------------------------- REM everything below should not need customizing REM --------------------------------------------

REM add required entries to the search path. REM NOTE: some entries may already be present, but this will do no harm. SET PATH=%MINGWPREFIX%\bin;%KDEPREFIX%\bin;%KDEPREFIX%\lib;%PERLPREFIX%\bin;%PATH%

REM we build in a subdirectory "build" of the sources. SET SOURCE_DIR=%~dp0 cd %~dp0 mkdir build cd build

cmake %SOURCE_DIR% -G "MinGW Makefiles" -DCMAKE_INSTALL_PREFIX=%KDEPREFIX% %ADD_CMAKE_FLAGS% mingw32-make install

REM to install to a different path (e.g. for packaging) use REM mingw32-make install DESTDIR=Some\Other\Folder

What next?

So you got it to work? Great! Then probably your next concern is how to distribute the binaries you just compiled. See Projects/KDE_on_Windows/Packaging for that.
