Note
These instructions are a work in progress, being based on the Linux Build instructions, there are some sections which need updating.


These instructions are for Unix and similar operating systems.

Preparation

Recommended setup

Here is recommendation of a directory structure:

C
\\kderoot
%USERPROFILE%\kde4\src\
source code
%USERPROFILE%\kde4\build\calligra
directory that Calligra will be built in
%USERPROFILE%\kde4\inst\
directory that Calligra will be installed in

The build directory is needed because you cannot (or should not) build Calligra inside the source directory; the source and build directory have to be separated.

Getting the source code

As Windows support is still being improved, it is recommended that you use the development version. If you require stability, it is recommended that you take advantage of the nightly builds.

The latest development version of Calligra is 3.1.0 Alpha; developers always refer to it as to Master. Once tested and released, it will become the new current stable version 3.1.


To retrieve the source code from Git you have to use the following setup:

Add the following text to %USERPROFILE%\.gitconfig:

[url "git://anongit.kde.org/"]
    insteadOf = kde:
[url "ssh://[email protected]/"]
    pushInsteadOf = kde:

Then execute

$ git clone kde:calligra

By using the kde: prefix, read access will automatically happen over Git, and authenticated SSH is only required for pushes.

Note that pushing your changes will only work if you have a KDE developer identity (https://identity.kde.org/register.php).

This will create a 'calligra' subdirectory with the complete source tree.

Build requirements

This section provides information about hard (required) and optional software packages needed to build the Calligra software.

Hard dependencies

Note
A note for developers: to add (or remove) a hard dependency, an explanation of the reason, and possibly a discussion must be posted in advance on [email protected] The new dependency need to be packaged in the most widely used distributions (Debian, Fedora Core, OpenSuSE, (K)ubuntu). First try to make your new feature optional.


Following are the general must-have dependencies for Calligra:

  • Qt 4.6.0 or newer
  • kdelibs and kdelibs development files
    • the minimal requirement is currently 4.3.0, any 4.3, 4.4 or 4.5 release packaged in your distribution is OK
    • On opensuse the development package is called libkde4-devel; on Ubuntu and Debian it is called kdelibs5-dev. (TODO: add info for other distributions)
    • Calligra should also build fine with either kdelibs from git repository (see techbase for an explanation on how to compile kdelibs from svn), needed for parts of Calligra build with the Mobile Frameworks Profile of the KDE platform (kword, kspread, kpresenter, krita)
  • kdebase/runtime 4.3 or newer
  • cmake 2.6.2 or newer
  • lcms 1.18 or newer
  • libpng development package (libpng14-devel on opensuse, libpng-dev on Ubuntu/Debian)
    • development packages for other libraries may be needed; on ubuntu/Debian these can be installed using 'apt-get build-dep kdelibs5'

For Tables:

  • libeigen 2.0

For Krita:

  • libeigen 2.0
  • libexiv2 >= 0.16
  • libqimageblitz

For Stage:

  • boost

For Kexi:

  • sqlite3 and sqlite3-devel packages (package names can differ on various distributions), version >= 3.6.16

Optional dependencies

All optional dependencies are logged at the end of the cmake run, so it is easy to figure out what is missing. The buildsystem also reports what component will bot be built because given missing dependency.

Simplified installation of dependencies on various distributions

Note
Most distribution don't ship calligra yet, so you may replace it by "koffice" or "koffice2" in those command lines
  • deb-based distributions (Debian, Ubuntu...): All the dependencies used for the packages can be installed by running
apt-get build-dep {packagename}

for instance on Ubuntu:

sudo apt-get build-dep calligra
  • OpenSuSE: All the dependencies used for building Calligra can be installed by running:
zypper si -d calligra
  • Fedora: All the dependencies used for building Calligra can be installed by running:
yum-builddep calligra
  • ArchLinux: All the dependencies used for building Calligra can be installed by running:
sudo pacman -S kdelibs kdepimlibs qca lcms2 hicolor-icon-theme sqlite3 gsl glew qimageblitz poppler-qt shared-mime-info openexr libqtgtl libpqxx freetds fftw libspnav automoc4 boost cmake eigen git pkgconfig pstoedit libwpd libwpg kdegraphics-libs docbook-xml docbook-xsl libgsf create-svn
  • Chakra: All the dependencies used for building Calligra can be installed by running:(need to enable unstable repo)
sudo pacman -S kdelibs kdepimlibs qca lcms2 hicolor-icon-theme sqlite3 gsl glew qimageblitz poppler-qt shared-mime-info openexr libqtgtl libpqxx freetds fftw libspnav automoc4 boost cmake eigen git pkgconfig pstoedit libwpd libwpg kdegraphics-common libgsf docbook-xml docbook-xsl create-svn

Build Calligra

Note
It is not possible to build Calligra in the source directory. Set up your directories as described in the Recommended setup section above


Type:

mkdir -p $HOME/kde4/build/calligra
mkdir -p $HOME/kde4/inst
cd $HOME/kde4/build/calligra
cmake -DCMAKE_INSTALL_PREFIX=$HOME/kde4/inst $HOME/kde4/src/calligra -DCMAKE_BUILD_TYPE=RelWithDebInfo

cmakekde tool can be used as explained on the build instructions for KDE4.

Then type:

make

Note that on dual-core machines compilation can be greatly speed up with the -j parameter of the make program, for example for dual-core:

make -j4

and for quad-core:

make -j8

Then type this command to install the software:

make install

Debugging options. Instead of setting CMAKE_BUILD_TYPE to "RelWithDebInfo" for cmake which gives an optimized Calligra with debug information, useful for bug reporting, one can set CMAKE_BUILD_TYPE to "Debug" to get a slower Calligra but with even more interesting debuggong (backtrace) information. For this replace -DCMAKE_BUILD_TYPE=RelWithDebInfo in the above cmake command with -DCMAKE_BUILD_TYPE=Debug.

Please follow the Running Calligra Applications instructions before trying to run an application.

Updating the already built software

If the source code has been checked out Subversion from trunk or a branch, it is possible to update the source code with newly added changes and build again. Usually only changing parts will be built, so this operation would be faster than building the source code from scratch.

Type:

cd $HOME/kde4/src/calligra
git pull
cd $HOME/kde4/build/calligra
make
make install
Note
make -j4 or make -j8 can be used instead of make to speedup the build on multicore machines


Note
The above recipe will not work if the source code has not been obtained from Subversion


Build only selected applications from Calligra

CMake comes with a command-line tool ccmake that lets you configure build options. You can use it after executing cmake and before executing make. To use it, go to the build directory and issue the following commands:

cd $HOME/kde4/build/calligra
ccmake .

ccmake is a text user interface application. Simple usage: move the selection using up/don arrow keys. Press Enter to set option ON/OFF (for text options, you enter the text). When you're done with setting the options, press c key to configure the source code to apply your changes. When done, press e key to exit. At any time you can press Ctrl+C to stop the application without saving your changes. Any change is saved to $HOME/kde4/build/calligra/CMakeCache.txt file. You can remove this file to get back to the default configuration (in this case you have to re-execute cmake first.

For applications that you do not want to compile, set the corresponding BUILD_{application} variable to "off", replacing {application} by the app's name. For instance, setting BUILD_krita to off will prevent Krita from being built.

Alternatively you can run "-DBUILD_{application}=off" from the cmake command line.

Running Calligra applications

There are two options to make the Calligra applications available for running.

  • Option 1: Being able to run Calligra applications from the command line. If you have installed Calligra in a different prefix than KDElibs (which was recommended in this document), you may want to set the following environment variable:
export KDEDIRS=/path/to/install:$KDEDIRS
export PATH=/path/to/install/bin:$PATH
export KDEHOME=/path/to/a/config/dir

And then you need to execute:

kbuildsycoca4

For example for the recommended directory structure:

export KDEDIRS=$HOME/kde4/inst:$KDEDIRS
export PATH=$HOME/kde4/inst/bin:$PATH
export KDEHOME=$HOME/kde4/.kde

It is important to set KDEHOME to a directory different of $HOME/.kde, and if the directory does not exist, it will be created automatically.

  • Option 2: Being able to run Calligra applications from the menu or by clicking on desktop icons. Instead of using KDEDIRS, you can add these lines to $HOME/.kde/share/config/kdeglobals file using text editor:
[Directories]
prefixes=/path/to/install

And then you need to execute:

kbuildsycoca4

The advantage of this is that KDE4 will always look for the services where Calligra is installed. For example for the recommended directory structure:

[Directories]
prefixes=$HOME/kde4/inst.

Executing unit tests

To be able to execute unit tests, you need to explicitely enable them in the build configuration. To do so, set the KDE4_BUILD_TESTS variable to "ON", either by issuing the command in the build directory:

cd $HOME/kde4/build/calligra
cmake -DKDE4_BUILD_TESTS=ON .

Or you can run ccmake . in the buld directory and set KDE4_BUILD_TESTS to "on".

You can then run the test by executing:

make test

or individually in the tests directories.

It is recommended to execute

make install

before running tests.

CMake Build Options

When you enter your build directory, you can type "ccmake ." to see many build options, e.g. you can turn off compilation of apps you don't want - you can save time when compiling.

Here is list for Krita related options:

  • HAVE_MEMORY_LEAK_TRACKER [On/Off] - You can turn on compilation of the tool in krita which detects memory leak. If you want to help debug Krita memory usage, it is useful. Otherwise you just slow down your Krita.
  • HAVE_BACKTRACE_SUPPORT [On/Off] - It is related to the memory leak tool. If you activate, you will be able to see code path which leads to memory leak.

Resources

Possible issues

If you get errors when running an application like:

krita(8565)/calligra (lib komain) KoPluginLoader::load: Loading plugin "Animation Tool" failed, 
"Cannot load library /home/michael/kde4/inst/lib/kde4/kpresentertoolanimation.so: 
(/home/michael/kde4/inst/lib/libkopageapp.so.7: undefined symbol:
_ZN28KoShapeContainerDefaultModel3addEP7KoShape)" ( 1 ) 

or crashes when starting an application, then you very likely have a version of Calligra installed through your package manager. As emphasized earlier in this document, you can only have one version of Calligra, and you should uninstall your packaged Calligra.
