Prerequisites for RPM
This page shows how to install the standard dependencies of apertium (and related packages) on RHEL / CentOS / Fedora / OpenSUSE and operating systems based on those.
If you don't plan on working on the core C++ packages (but only want to work on / use language pairs), you can install all prerequisites with yum/zypper, using User:Tino Didriksen's repository. The first line here adds this repository to yum/zypper, then we can just install the usual way:
wget http://apertium.projectjj.com/rpm/install-nightly.sh -O - | sudo bash # RHEL/CentOS/Fedora: sudo yum install apertium-all-devel # OpenSUSE: sudo zypper install apertium-all-devel
For a list of available language pairs and other packages, see https://build.opensuse.org/project/show/home:TinoDidriksen:nightly
If you want to work on a language pair, you'll have to check out the language data from SVN and compile it (but you can still skip the stuff about installing apertium/lttoolbox/apertium-lex-tools).
Otherwise, e.g. if you want to work on the core C++ packages, continue to Minimal installation from SVN.
