jpl not installed on Ubuntu

[db]

Hello,

I have installed (by using Synaptic) Swi-Prolog 5.6.55 64 bits
on a PC quad core running under Ubuntu 8.1.
I have discovered that jpl is not in the provided package.

I see no clear solution in the web
(all proposed solutions failed).
Could you tell what are the files I need to install,
how I can get them, and how to install them ?

Thanks you very much in advance.

On Windows you could (hypothetically, since all Windows builds include
JPL) supply the essential native, Java and Prolog libraries

pl/bin/jpl.dll
pl/lib/jpl.jar
pl/library/jpl.pl

and extra material in

pl/doc/packages/examples/jpl
pl/doc/packages/jpl

then remake the library index (so that jpl.pl can be autoloaded) but
for Linux I think the official advice is: either use the RPM package
from http://www.swi-prolog.org/download/stable or build and install
from sources (at same URL).

(If you can get hold of a jpl.dll-equivalent shared object library for
your version of Linux, you could copy the (platform-independent)
jpl.jar and jpl.pl from another installation.)

First thanks for your message.

I have found the files,
for Linux jpl.dll is replaced by libjpl.so .
Under Linux (Ubuntu in my case) I don't know
where I must place these files.

I mus confess that I don't know how 'remake the library index'.
Could anyone explain me ?

I have tried but I failed to install it.
There are bugs or errors when we install to Ubuntu.

Thanks again.

As above, where pl is the new directory into which SWI-Prolog was
installed. If you don't know where it is, check your environment
variables for SWI_HOME_DIR or similar, or search for a SWIPL file e.g.
find -name syspred.pl (I don't use Linux so these are just hints).

See the Reference Manual or just run

1 ?- make.

at your SWI-Prolog prompt.
