Matxin

Matxin is a free software machine translation engine related to Apertium. It allows for deeper transfer than can be found in Apertium. The linguistic data available under a free-licence is a fraction of the data that is used in the papers and descriptions of the subject, so naturally the translations from the pair will be less good than you can find results in the paper.

Prerequisites

• libcfg+ — http://platon.sk/upload/_projects/00003/libcfg+-0.6.2.tar.gz
• BerkleyDB — sudo apt-get install libdb4.6++-dev
• libomlet — https://lafarga.cpl.upc.edu/frs/download.php/130/libomlet-0.97.tar.gz
• libfries — https://lafarga.cpl.upc.edu/frs/download.php/129/libfries-0.95.tar.gz
• FreeLing (version 1.5) — https://lafarga.cpl.upc.edu/frs/download.php/90/FreeLing-1.5.tar.gz

If you're installing into a prefix, you'll need to set two environment variables: CPPFLAGS=-I<prefix>/include LDFLAGS=-L<prefix>/lib ./configure --prefix=<prefix>

Troubleshooting

libfries

If you get the error to do with "strlen was not declared in this scope", add #include <string.h> to the file src/include/fries/language.h.

If you get the error to do with "set_union was not declared in this scope", add #include <algorithm> to the file src/libfries/RGF.cc.

libomlet

If you get the error to do with "exit was not declared in this scope", add #include <stdlib.h> to the file src/libomlet/adaboost.cc.

FreeLing

If you get the error to do with "exit was not declared in this scope", add #include <stdlib.h> to the files src/utilities/indexdict.cc, src/libmorfo/accents.cc, src/libmorfo/accents_modules.cc, src/libmorfo/dictionary.cc, src/libmorfo/tagger.cc, src/libmorfo/punts.cc, src/libmorfo/maco_options.cc, src/libmorfo/splitter.cc src/libmorfo/suffixes.cc src/libmorfo/senses.cc src/libmorfo/hmm_tagger.cc.

If you get the error to do with "strlen was not declared in this scope", add #include <string.h> to the files src/libmorfo/automat.cc, src/libmorfo/dates.cc, src/libmorfo/locutions.cc, src/libmorfo/maco.cc, src/libmorfo/np.cc, src/libmorfo/nec.cc, src/libmorfo/numbers.cc, src/libmorfo/numbers_modules.cc, src/libmorfo/quantities.cc, src/libmorfo/tokenizer.cc and src/libmorfo/dates_modules.cc.

If you get the error to do with "memcpy was not declared in this scope", add #include <string.h> to the files src/include/traces.h, src/libmorfo/dictionary.cc, src/libmorfo/traces.cc src/libmorfo/senses.cc,

Building

Checkout

$ svn co http://matxin.svn.sourceforge.net/svnroot/matxin

First comment out the deformatters in the Makefile.am as they don't build properly.

Then do:

$ aclocal; automake -a; autoconf
$ LTTOOLBOX_DIR=/home/fran/svnroot/local/unstable/ LDFLAGS="-L/home/fran/local/lib -L/usr/lib" 
CPPFLAGS="-I/home/fran/local/include" ./configure --prefix=/home/fran/local/

You will probably need to fix a few things in the file: src/Makefile to get it to build, for example add:

DEFAULT_INCLUDES = -I. -I$(srcdir) -I/usr/include/libxml2
CPPFLAGS = -I<prefix>/include/lttoolbox-2.0 -I<prefix>/include
