Matxin

From Apertium
Jump to navigation Jump to search

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

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 #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, src/libmorfo/feature_extractor/fex.cc

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

If you get the error: 

In file included from analyzer.cc:72:
config.h:32:18: error: cfg+.h: No such file or directory

Run make like make CXXFLAGS=-I/home/fran/local/include

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 in the file configure.ac, change 

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

for 

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

CFLAGS="$CFLAGS $MATXIN_CFLAGS"
CPPFLAGS="$CPPFLAGS $MATXIN_CPPFLAGS"
LIBS="$LIBS $MATXIN_LIBS"

Then you need to comment out the check for gcc version in configure.ac 

#
# 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
#

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
