Prerequisites for Mac OS X

This page shows how to install the standard dependencies of apertium (and related packages) on Mac OS X.

First of all, you need:

• a full installation of XCode (http://developer.apple.com/tools/xcode/) including the Command Line Tools

  (http://railsapps.github.io/xcode-command-line-tools.html is nice guide if you get stuck here)

• Macports (http://www.macports.org/install.php)

Then install the apertium dependencies with Macports like this:

sudo port install autoconf automake expat flex \
gettext gperf help2man libiconv libtool \
libxml2 libxslt m4 ncurses p5-locale-gettext \
pcre perl5 pkgconfig zlib gawk subversion

If you need vislcg3/cg-proc/cg-comp (Constraint Grammar), you should also do:

sudo port install icu cmake boost google-perftools

You can run http://apertium.projectjj.com/osx/install-nightly.sh to install the latest compiled version of apertium, lttoolbox, vislcg3 and HFST – that way you don't have to check out, build and install these by hand.

Once you've installed these packages, continue to Minimal installation from SVN (and skip the parts about lttoolbox/apertium, just install the language pair/language data itself if you ran http://apertium.projectjj.com/osx/install-nightly.sh as mentioned above).

(Note: it is technically possible to install apertium and lttoolbox from Macports, but the version there is very out of date. It is not recommended if you want to do development.)
