Digikam/Compilation on Kubuntu

How to compile digikam svn in Kubuntu > 8.10 (Intrepid Ibex, Jaunty Jackalope)

The new Kubuntu version 8.10 uses kde4 only instead of the kde3/4 mix of earlier versions. Here is a list of instructions that should get you a working snapshot of the current digikam SVN using Kubuntu 8.10 or higher.

Essentially, these instructions repeat the kde4-related instructions of http://www.digikam.org/drupal/download?q=download/svn, plus a list of kubuntu packages to install and some environment variable settings for the compilation.

This tutorial has been tested on a fresh Kubuntu 9.04 Jaunty.

Installing dependencies

Assuming you have a fresh install of Kubuntu 8.10, you first need to install some additional packages:

<syntaxhighlight lang="text"> sudo aptitude install subversion cmake kdelibs5-dev g++ sane libsane-dev gphoto2 libgphoto2-2-dev blitz++ libexiv2-dev libqimageblitz-dev xorg-dev libimlib2-dev libmarble-dev libqt4-sql-sqlite marble marble-data kdepimlibs5-dev libkdcraw7-dev libkexiv2-7-dev gettext

For latest SVN (almost from 10 Aug 2009) you need also

<syntaxhighlight lang="text"> sudo apt-get install libstreams-dev libstreamanalyzer-dev

which are used by the Strigi interface.

For some additional plugins like redeye-removal and automatic lens correction, you need to download, compile and install extra libraries. These are optional, if you skip the following step and go directly to "First svn checkout" below, digikam will also compile fine, but miss these extra features.

For the auto lens correction tool, download liblensfun from http://lensfun.berlios.de/, for example lensfun-0.2.3.tar.bz2. Then, in the folder you downloaded to,

<syntaxhighlight lang="text"> tar -xjvf lensfun-0.2.3.tar.bz2 cd lensfun-0.2.3 ./configure --prefix=/usr make all sudo make install

For red eye removal, get opencv: Download opencv-1.0.0.tar.gz at http://downloads.sourceforge.net/opencvlibrary/opencv-1.0.0.tar.gz?modtime=1162852454&big_mirror=1, then

<syntaxhighlight lang="text"> tar -xzvf opencv-1.0.0.tar.gz cd opencv-1.0.0 ./configure make sudo make install

First svn checkout

To download the digikam source code, first create a directory where you want to download it to and go there, for example

<syntaxhighlight lang="text"> mkdir -p ~/down/svn cd ~/down/svn

Now you can do the svn checkout, as described on the digikam website:

<syntaxhighlight lang="text"> svn co -N svn://anonsvn.kde.org/home/kde/trunk/KDE/kdegraphics cd kdegraphics svn up libs svn up cmake cd ..

svn co -N svn://anonsvn.kde.org/home/kde/trunk/extragear/graphics cd graphics svn up digikam svn up kipi-plugins svn up cmake

Set variables

Before compiling, you need to set some environment variables (Thanks to Geoff on the digikam list for telling me the correct settings):

<syntaxhighlight lang="text"> DIGIKAMKDE4=/usr export KDEDIR=$DIGIKAMKDE4:/usr/lib/kde4 export KDEDIRS=$DIGIKAMKDE4:/usr/lib/kde4 export KDEHOME=$HOME/.kde export QTDIR=/usr/lib/qt4 export PATH=$DIGIKAMKDE4/bin:/usr/local/bin:$QTDIR/bin:$KDEDIR/bin:$QTDIR/bin:/usr/local/bin:$PATH export KDETMP=/tmp/$USER-kde4 export KDEVARTMP=/var/tmp/$USER-kde4 export LD_BIND_NOW=42 export LD_LIBRARY_PATH=$KDEDIR/lib:$QTDIR/lib:$DIGIKAMKDE4/lib:/usr/lib/kde4:/usr/lib:/usr/lib/kde4/libexec:$LD_LIBRARY_PATH export PKG_CONFIG_PATH=$DIGIKAMKDE4/lib/pkgconfig:/usr/lib/pkgconfig:/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH

Compile and install

Now you're all set for compiling, starting with the libs. Do

<syntaxhighlight lang="text"> cd ../kdegraphics mkdir build cd build cmake -DCMAKE_BUILD_TYPE=debugfull -DCMAKE_INSTALL_PREFIX=$DIGIKAMKDE4 ../../kdegraphics make sudo make install

For the last step (installation), you will be prompted for your root password.

Now for digikam itself:

<syntaxhighlight lang="text"> cd ../../graphics mkdir build cd build cmake -DCMAKE_BUILD_TYPE=debugfull -DCMAKE_INSTALL_PREFIX=$DIGIKAMKDE4 ../../graphics make sudo make install

Afterwards, you can start digikam from the kde start menu (under "graphics"), from krunner (alt+f2), or from the command line as "digikam".

Note that the above procedure will give you a really recent development snapshot, so some instabilities and bugs can be expected. However, most parts are quite reliable already. Most of the functionality of the 0.9 series has been reproduced, and many new features have been added ...

If at a later time, you want to update to the latest status of development, you can proceed as above, but replace step 2 "first svn checkout" by the following.

Subversion upgrade

Go to your svn directory (for example ~/down/svn, otherwise change the path below correspondingly) and upgrade:

<syntaxhighlight lang="text"> cd ~/down/svn/kde4/kdegraphics svn up libs svn up cmake cd ~/down/svn/kde4/graphics svn up digikam svn up kipi-plugins svn up cmake

Today, libkexiv2-7 and libkexiv2-7-dev have to be installed in your system. libkexiv2-6 and libkexiv2-dev are not supported

The remaining steps of setting variables, compiling and installing are unchanged.
