These instructions are for Unix and similar operating systems.

Preparation

Warning

First, to avoid conflicting copies of software, make sure you do not have other copy of Calligra or Calligra software either installed through the package manager of your distribution or installed in any other way. Calligra and Calligra are mutually exclusive!

Recommended setup

Here is recommendation of a directory structure:

$HOME/kde4/src/: source code
$HOME/kde4/build/calligra: directory that Calligra will be built in
$HOME/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.

Advantages of this setup:

It is possible to have different builds (e.g. with different options out of the same source code)
David Faure's scripts can be used to make development easier. With those scripts "make" can be typed in the source directory and building will happen in the right (build) directory automatically.

Also, check the Techbase instructions on setting up a build environment. That contains some useful scripts and functions.

Geting the source code

There are two options: to get the source code for the latest stable version or for the for the development version. The later option is needed to test, check and give feedback about features that is in development and have not been released yet. If unsure pick the stable version.

Geting the source code for the latest stable version

The latest stable Calligra version is 3.1.0.

Visit download.kde.org for the latest source code: calligra-3.1.0.tar.bz2
Check release notes on calligra.org

Get the source code for the development version

Warning

You cannot convert your KOffice SVN checkout to a Calligra git checkout. You will need to get the Calligra source code using git and manually apply your changes again.

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

XXX: Here we should explain local branches, staging and always-release-ready Master, if we have that setup. XXX

Option 1: directly from git

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

Add the following text to your ~/.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).

The $HOME/kde4/src/calligra directory will be created regardless of the way how the source code has been downloaded.

Option 2: download a repository tarball

Go to https://projects.kde.org/projects/extragear/calligra. Press the "Tarball" button. Copy the url text and paste it on your command line. It will look like:

wget -c http://anongit1.kde.org/calligra/calligra-latest.tar.gz

Unpack and cd into directory, then run

$ ./initrepo.sh

From now on, you can run

$ git pull

to update, or

$ git rebase origin/master

if you have local changes

Option 3: if beta or rc version was released, the source code for the latest beta can be found on KDE's ftp calligra-latest. Uncompress the code so that $HOME/kde4/src/calligra is created.

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
kdelibs, the minimal requirement is currently 4.3.0. But Calligra should build fine with either kdelibs from svn (see techbase for an explanation on how to compile kdelibs from svn), or any 4.3, 4.4 or 4.5 release packaged in your distribution (4.4.x is recommended) Parts of Calligra build with the Mobile Frameworks Profile of the KDE platform (kword, kspread, kpresenter, krita)
kdebase/runtime 4.3 (4.4.x is recommended)
kdepimlibs 4.3 (4.4.x is recommended)
cmake 2.6.2
lcms 1.18

For KSpread:

libeigen 2.0

For Krita:

libeigen 2.0
libexiv2 >= 0.16
libqimageblitz

For KPresenter:

boost

For Kexi:

sqlite and sqlite-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

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 calligra2

ArchLinux: All the dependencies used for building Calligra can be installed by running:

sudo pacman -S docbook-xml exiv2 glew graphicsmagick gsl kdebase-runtime kdepimlibs lcms libwpd poppler-qt pstoedit qca qimageblitz shared-mime-info wv2 xdg-utils

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 .

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=$KDEDIRS:/path/to/install
export PATH=$PATH:/path/to/install/bin
export KDEHOME=/path/to/a/config/dir

And then you need to execute:

kbuildsycoca4

For example for the recommended directory structure:

export KDEDIRS=$KDEDIRS:$HOME/kde4/inst
export PATH=$PATH:$HOME/kde4/inst/bin
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 cmake -DKDE4_BUILD_TESTS=ON, or by running ccmake .. Both commands must be executed in the build directory.

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.
