Installation of grammar libraries

Some language pairs need code libraries which are not part of Apertium core. You may not know until a compile sighs, 'fail, fail, fail'. You can tell if a package requires CG if it has an .rlx file, and HFST if it has a .lexc file.

Fortunately (for those who use Apertium repositories), these rule-builders are available through the private repository packages. You can access and install the packages even if your Apertium is a compiled build. Otherwise, you will need to compile.

VISL CG3 ('vislcg3' / 'cg-proc' / 'cg-comp')

e.g. the Macedonian→English, Breton→French, Nynorsk-Bokmål pairs.

packages

Debian / Ubuntu Derivatives

wget http://apertium.projectjj.com/apt/install-nightly.sh -O - | sudo bash
sudo apt-get install cg3

compiling

See installing vislcg3.

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, in Macports as icu).

HFST ('hfst-proc' / 'hfst-lexc' / 'hfst-twolc')

e.g. the Turkic and Saami pairs.

packages

Debian / Ubuntu Derivatives

wget http://apertium.projectjj.com/apt/install-nightly.sh -O - | sudo bash
sudo apt-get install hfst

compiling
