'''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.
'''Matxin''' is a free software machine translation engine related to [[Apertium]]. It allows for deeper transfer than can be found in Apertium.


This page describes how to install the system, see [[Matxin#Documentation]] below for how to create or maintain language pairs.
==Prerequisites==


==Installation==
* 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>
* [[lttoolbox]] (version 2.0 -- yes, this is ancient)

==Troubleshooting==

;libfries

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

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

;libomlet

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

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

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

==Building==


;Checkout


set your <code>ACLOCAL_PATH</code> to include the path to <code>matxin.m4</code>
<pre>
$ svn co http://matxin.svn.sourceforge.net/svnroot/matxin

==Documentation==
First comment out the deformatters in the <code>src/Makefile.am</code> as they don't build properly.

</pre>

Then in the file <code>configure.ac</code>, change

<pre>
AC_CHECK_LIB(lttoolbox-2.0, main, [], [AC_MSG_ERROR([library 'lttoolbox' is required for Matxin])])
</pre>

for

<pre>
PKG_CHECK_MODULES(MATXIN, [lttoolbox-2.0 >= 2.0.0],,exit)

CFLAGS="$CFLAGS $MATXIN_CFLAGS"
CPPFLAGS="$CPPFLAGS $MATXIN_CPPFLAGS"
LIBS="$LIBS $MATXIN_LIBS"
</pre>

Then you need to comment out the check for gcc version in <code>configure.ac</code>

<pre>
#
# GCC version check
#
#AC_MSG_CHECKING(for GCC version)
#gccver=`$CXX -dumpversion`
#AC_MSG_RESULT($gccver);
#case "$gccver" in
# 4.3*)
# AC_MSG_ERROR([GCC version must be <= 4.2])
#esac
#
</pre>

Then do:

<pre>
$ 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/
</pre>

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

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

==Executing==

<pre>
$ export MATXIN_DIR=<prefix>
$ echo "Esto es una prueba" | \
./Analyzer -f $MATXIN_DIR/share/matxin/config.cfg | \

Matxin is a free software machine translation engine related to Apertium. It allows for deeper transfer than can be found in Apertium.

This page describes how to install the system, see Matxin#Documentation below for how to create or maintain language pairs.

Installation[edit]

$ git clone https://github.com/matxin/matxin.git
$ cd matxin/
$ ./autogen.sh 
$ make
# make install

Language pairs[edit]

Troubleshooting[edit]

Can't find AP_MKINCLUDE



set your ACLOCAL_PATH to include the path to matxin.m4

Documentation[edit]

Contact[edit]

Questions and comments about Matxin can be sent to their mailing list matxin-devel, or to the apertium-stuff list.
