Installing Krita on Slackware 14.1

This is a guide on how to build Krita on Slackware 14.1. This is based on this guide for linux.

1. removepkg calligra

2. Install some dependencies from Slackbuilds.

   gsl
   libgexiv2
   libpqxx
   pstoedit
   

3. Get Krita.

   The original guide recommends building in ~/kde4 but I moved i to /opt/kde4.

   mkdir -p /opt/kde4/build /opt/kde4/src /opt/kde4/inst
   cd /opt/kde4/src
   git clone git://anongit.kde.org/calligra.git
   

4. Configure and build.

   There’s a problem with tifflib. (My version is Krita: 2.9.6 (gitb804a35), you may or may not run into this problem).

   Change /opt/kde4/src/calligra/krita/plugins/formats/tiff/kis_tiff_converter.cc from

   #if TIFFLIB_VERSION < 20111221
   typedef size_t tmsize_t;
   #endif
   

   to

   typedef size_t tmsize_t;
   

   Then we can build

   cd /opt/kde4/build
   cmake -DCMAKE_INSTALL_PREFIX=/opt/kde4/inst /opt/kde4/src/calligra \
       -DCMAKE_BUILD_TYPE=RelWithDebInfo -DPRODUCTSET=KRITA
   make -j5
   make install -j5
   

   Where X in jX is 1 + # processors. The build process is quite slow.

5. Add /opt/kde4/inst/bin to PATH and /opt/kde4/inst to KDEDIRS.

6. Register krita to the system kbuildsyscoca4, but worked for me without it (I don’t use kde).

And launch with krita.
