Minimal installation from SVN

Installing apertium and a language pair

If you have limited bandwidth or disk space, you might consider to download and install just 3 things:

• lttoolbox
• apertium
• the language pair(s) your are interested in

Here are the commands if you would like the Esperanto-English pair:

svn checkout http://apertium.svn.sourceforge.net/svnroot/apertium/trunk/lttoolbox
svn checkout http://apertium.svn.sourceforge.net/svnroot/apertium/trunk/apertium
svn checkout http://apertium.svn.sourceforge.net/svnroot/apertium/trunk/apertium-eo-en

To see the available language pairs, go to https://apertium.svn.sourceforge.net/svnroot/apertium/trunk/.

Note: certain packages have to be installed before installing Apertium, see the system-specific HOWTO's under Installation for how to install the requirements.

Typically, Apertium is installed under the directory /usr/local. However, if you want it installed somewhere else or don't want to install it as root, do:

PREFIX=/path/to/where/I/want/Apertium
PKG_CONFIG_PATH=$PREFIX/lib/pkgconfig
export PKG_CONFIG_PATH

Then, in the lttoolbox and apertium directories, do:

./autogen.sh --prefix=$PREFIX
make
make install
ldconfig

Warning: If you didn't specify $PREFIX or don't know what this means then do:

./autogen.sh 
make
make install
ldconfig

(If you didn't specify a prefix, use sudo before the last two commands.)

Then, in the directory apertium-eo-en, do:

./autogen.sh --prefix=$PREFIX
make
make install

(Use sudo before the last command if you didn't specify a prefix.)

For language pairs that use CG (vislcg3 / cg-proc)

Many language pairs now use CG (e.g. Macedonian→English, Breton→French, Nynorsk-Bokmål, …). For these, you need vislcg3 beforehand. See Vislcg3#Installing_VISL_CG3 for installation (use ./cmake.sh -DCMAKE_INSTALL_PREFIX=<prefix> if you're installing to a prefix).

Note that you have to have ICU installed beforehand (available through most GNU/Linux package managers, in Arch Linux as icu, in Debian/Ubuntu as libicu-dev).

For language pairs that use HFST

Many language pairs now use HFST (e.g. the Turkic and Saami ones). For these, you need hfst and typically OpenFST and foma beforehand. Follow the installation guides first for Foma and OpenFST, then HFST.
