Installation troubleshooting

Errors

lt-comp: error while loading shared libraries: liblttoolbox3-3.0.so.0: cannot open shared object file: No 
such file or directory

This is because lt-comp cannot find where your liblttoolbox libs are installed. You may need to do one of several things:

If you have installed it in an odd location, do: export LD_LIBRARY_PATH=/path/to/wierd/libdir
If you have installed it in /usr/local
1. Check to see if /usr/local/lib is in /etc/ld.so.conf, if it is, run ldconfig
2. If it isn't, either add /usr/local/lib to /etc/ld.so.conf and re-run ldconfig, or do step 1.

checking for pcreposix.h... no
configure: error: *** unable to locate pcreposix.h include file ***

You don't have the PCRE (Posix-compatible regular expressions) library header files installed, if you're in Debian or Ubuntu, do:

# apt-get install libpcre3-dev

$  echo "Eso es un test" | apertium es-ca
Error: Mode es-ca does not exist. Try one of:
README

Looks like you don't have any language pairs installed, did you run make install in the language pair directory?

If you did, email the output of

$ cat /usr/local/bin/apertium | grep -e APERTIUM -e DEFAULT

...obviously replace /usr/local/bin/apertium with the location of the $(prefix)/bin/apertium

and the steps you took to compile apertium to the apertium-stuff mailing list.
