Installation instructions for GIMP 2.8
--------------------------------------

There are some basic steps to building and installing GIMP.

GIMP 2.8 replaces earlier GIMP 2.x versions. It is advised that you
uninstall them before installing GIMP 2.8. If you want to keep your
older GIMP 2.x installation in parallel to GIMP 2.8, you have to
choose a separate prefix which is not in your default library search
path.

GIMP 2.8 is fully backward compatible to all earlier GIMP 2.x version.
Plug-ins and scripts written for GIMP 2.6 or earlier GIMP 2.x versions
will continue to work and don't need to be changed nor recompiled to
be used with GIMP 2.8.

The most important part is to make sure the requirements for a build
are fulfilled.  We depend on a number of tools and libraries which are
listed below. For libraries this means you need to also have the
header files installed.


  ******************************************************************
  * Unless you are experienced with building software from source, *
  * you should not attempt to build all these libraries yourself!  *
  * We suggest that you check if your distributor has development  *
  * packages of them and use these instead.                        *
  ******************************************************************


  1. You need to have installed a recent version of pkg-config available
     from http://www.freedesktop.org/software/pkgconfig/.

  2. You need intltool (at least 0.40.1, but preferably a newer version).
     Intltool can be downloaded from
     http://ftp.gnome.org/pub/gnome/sources/intltool/

  3. You need to have GEGL version 0.2.0 or newer and babl version
     0.1.10 or newer. You can get them from http://gegl.org/ or clone
     them from the GNOME git repository:

       git://git.gnome.org/babl
       git://git.gnome.org/gegl

  4. You need to have installed GTK+ version 2.24.10 or newer.
     GIMP also need a recent versions of GLib (>= 2.30.2), GDK-Pixbuf
     (>= 2.24.1), and Pango (>= 1.29.4). Sources for these can be grabbed
     from ftp://ftp.gtk.org/.

  5. We use cairo >= 1.10.2, which is hosted at
     http://www.cairographics.org/.

  6. We require PangoCairo, a Pango backend using Cairo. Make sure you
     have Cairo, FreeType2 and fontconfig installed before you compile
     Pango. GIMP depends on freetype2 being newer than version 2.1.7
     and fontconfig 2.2.0 or newer. Older versions are known to have
     bugs that seriously affect the stability of GIMP.

     On Windows platforms in particular, we recommend fontconfig 2.11.1
     or newer. Older versions may end up in broken font handling, due to
     inadequate font configuration: font aliases not configured,
     synthetic bold/italic variants unavailable, cache folder in temp
     directory resulting in slow startups, etc.

  7. We use dbus-glib if available. Grab it from
     http://dbus.freedesktop.org/releases/dbus-glib/

  8. Access of remote files is implemented in the URI plug-in. There
     are several possible implementations for this. The implementation
     used is determined when you configure GIMP. By default the
     GIO/GVfs backend is used. If you don't have GVfs support on your
     target platform, you should pass the '--without-gvfs' option to
     configure. The configure script will then try to detect another
     method for accessing remote files.

  9. You may want to install other third party libraries or programs
     that are needed for some of the available plug-ins. We recommend
     to check that the following libraries are installed: lcms,
     libpng, libjpeg, libpoppler (and poppler-data, optional encoding
     package, necessary to import PDF with CJK and cyrillic text),
     libtiff, webkit, libmng, librsvg, libwmf, libz, libbzip2, libgs
     (Ghostscript), libaa and libjasper.

 10. The Python extension requires Python 2 development headers to be
     present. You will also need PyGTK and the respective development
     headers.

 11. Configure GIMP by running the `configure' script. You may want
     to pass some options to it, see below.

 12. Build GIMP by running `make'. The use of GNU make is recommended.
     If you need to tweak the build to make it work with other flavours
     of make, we'd appreciate if you'd send us a patch with the changes.

 13. Install GIMP by running `make install'. In order to avoid clashes
     with other versions of GIMP, we install a binary called gimp-2.8.
     By default there's also a link created so that you can type 'gimp'
     to start gimp-2.8.

Please make sure you don't have any old GTK+-2.x, jpeg, etc. libraries
lying around on your system, otherwise configure may fail to find the
new ones.
