This guide shows you how to download, configure, compile and install core apertium packages and language data. It assumes you've already installed the '''prerequisites''' for your system – if you have not, see the system-specific guides under [[Installation]].

==Installing apertium and a language pair==


The page contained,
For most language pairs, these are the packages you need:


* How to compile Apertium core. For this, please see [[Install Apertium core by compiling]]
* lttoolbox
* apertium
* apertium-lex-tools
* the language pair(s) your are interested in


* How to create new, or compile exisitng, language builds. For a new or mixed pair, see [[How to bootstrap a new pair]]. For existing pairs, see [[Install language data by compiling]],
Here are the commands if you would like the Esperanto-English pair:
<pre>
svn checkout https://svn.code.sf.net/p/apertium/svn/trunk/lttoolbox
svn checkout https://svn.code.sf.net/p/apertium/svn/trunk/apertium
svn checkout https://svn.code.sf.net/p/apertium/svn/trunk/apertium-lex-tools
svn checkout https://svn.code.sf.net/p/apertium/svn/trunk/apertium-eo-en
</pre>


* Details about the HFST and CG modules. Please see [[Installation of grammar libraries]]
If you want another pair than eo-en, only the last line needs changing. To see the available 'released' language pairs, go to https://svn.code.sf.net/p/apertium/svn/trunk/ (pairs which are in development are in the incubator/nursery/staging subdirectories of https://svn.code.sf.net/p/apertium/svn/).


Or start from the information root at [[Installation]]?


By default, Apertium is installed under the directory <code>/usr/local</code>, which requires root (sudo) access when installing. If that's fine with you, do:
<pre>
LD_LIBRARY_PATH=/usr/local/lib:${LD_LIBRARY_PATH}
export LD_LIBRARY_PATH
PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:${PKG_CONFIG_PATH}
export PKG_CONFIG_PATH
</pre>
You should also put those lines in your ~/.bashrc so you don't have to paste them into every terminal you open.

However, if you want it installed somewhere else or don't want to install it as root, instead do:
<pre>
PREFIX=$HOME/local # or wherever you want apertium stuff installed
LD_LIBRARY_PATH=$PREFIX/lib:${LD_LIBRARY_PATH}
export LD_LIBRARY_PATH
PKG_CONFIG_PATH=$PREFIX/lib/pkgconfig:${PKG_CONFIG_PATH}
export PKG_CONFIG_PATH
</pre>
You should also put those lines in your ~/.bashrc so you don't have to paste them into every terminal you open.


Now you'll configure, build and install each of the modules you checked out, in this order:
# <code>lttoolbox</code>
# <code>apertium</code>
# <code>apertium-lex-tools</code>
# the language pair (e.g. <code>apertium-eo-en</code>)

<code>cd</code> to each of the directories before you run the the commands shown below.

If you specified a <code>$PREFIX</code> (e.g. to avoid installing as root), then do this in each directory:
<pre>
./autogen.sh --prefix=$PREFIX
make
make install
ldconfig
</pre>

If you didn't specify <code>$PREFIX</code> or don't know what this means, then do this in each directory:
<pre>
./autogen.sh
make
sudo make install
sudo ldconfig
</pre>


(If you're on a Mac, you don't need to do ldconfig, don't worry that it fails.)


Now test that it works. The command <code>apertium -l</code> should show a list of translation directions, of the form "from-to". Pick one, and do
<pre>
echo 'This is a test sentence.' | apertium from-to
</pre>
replacing from-to with the direction you want.

==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 <code>vislcg3</code> beforehand. See [[Vislcg3#Installing_VISL_CG3]] for installation (use <code>./cmake.sh -DCMAKE_INSTALL_PREFIX=<prefix></code> if you're installing to a prefix).

Note that you have to have [http://site.icu-project.org/ ICU] installed beforehand (available through most GNU/Linux package managers, in Arch Linux as <code>icu</code>, in Debian/Ubuntu as <code>libicu-dev</code>).

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