Error "undefined symbol: PL_new_atom" using jpl on Ubuntu 9.04

[Samuel Lampa-3]

Hello,

I'm trying to use a system built upon Swi-prolog (blipkit) through jpl
for integration into a Java project.

OS: Ubuntu 9.04.
SWI-Prolog version: 5.7.15 (Checked out from Git and compiled from
source, including all packages)

Blipkit works fine on my system when starting blip from the commandline
(Blipkit is basically a SWI-Prolog shell that loads extra prolog modules
at startup). But when I try to load the same modules from Java, via jpl,
I constantly get this error:

/usr/lib/jvm/java-1.5.0-sun-1.5.0.19/bin/java: symbol lookup error:
/usr/local/lib/pl-5.7.15/lib/i686-linux/sgml2pl.so: undefined symbol:
PL_new_atom

I think I've located the defenition of PL_new_atom, to the file
src/pl-fli.c:282 but nothing seems wrong with that.

Furthermore, the JPL Java test "Test" in the examples folder works well.
"make check" results in a whole lot of errors though (but I read
somewhere that the tests for this one checks very specific paths to the
java bin et.c. which I suppose could easily differ between systems).

So, trying to figure out a possible reason.

In the packages/jpl/ISSUES file there is some information which makes me
thinking if it can be relevant here, but of which I don't fully
understand the consequences:

packages/jpl/ISSUES says:
>                                                            <snip>  ...If

> Prolog symbols are resolved against the application.

Could this mean that when prolog is started from Java, it does not have
access to the same shared libraries et.c. (for example the definitions
for PL_new_atom), or am I wrong?

Any other hints, or anybody else having experience from working with the
jpl on Ubuntu?
Any hints are welcome!

[Andrew Koster]

You need to add the LD_PRELOAD environment variable. In it, specify  
the location of the swipl libraries. There's a more detailed post in  
the mailing list which is where I found how to do it.

Thanks Andrew!

Your answer contained the solution. I had encountered the LD_PRELOAD
trick before but had additional problems, but your answer encouraged me
to continue researching this path and now I got it working when starting
Java from commandline! I still have to learn how to do the below things
in Eclipse also though, so any tips regarding that are highly welcome.

=== Solving my additional problems using LD_PRELOAD ===

|(Documenting this here, in case it helps anybody else with similar
problems.)

I wanted to call java with a custom script/command line call rather than
using the run.sh (and subsequent calls to env.sh) scripts in the
examples packaged with jpl, in order to know exactly what is needed to
do in Eclipse later. This gave me some additional trouble.||
|
I had the problem that when using LD_PRELOAD to load libjpl.so,
libjava.so and libjvm.so suddenly wasn't found, but this was solved by
first running:

  export
LD_LIBRARY_PATH=|"/usr/lib/jvm/java-1.5.0-sun-1.5.0.19/jre/lib/i386/client/:/usr/lib/jvm/java-1.5.0-sun-1.5.0.19/jre/lib/i386/"

I also had to run (The second path is just the path to the jpl Test
classes):

  export
CLASSPATH="||/usr/local/lib/pl-5.7.15/lib/jpl.jar:/home/samuel/install/swi-prolog/pl57/packages/jpl/examples/java/Test"
||
So now I can fire up the Test class (which I modified so it loads all
the blipkit modules) with the following command:
||
  LD_PRELOAD=/usr/local/lib/pl-5.7.15/lib/i686-linux/libjpl.so java
-Djava.library.path=/usr/local/lib/pl-5.7.15/lib/i686-linux/ Test

I have documented the changes to Test.java, in my project blog:

 
http://saml.rilspace.com/content/finally-got-blipkit-started-from-java-via-jpl


Again, many thanks!

Regards
Samuel

[Samuel Lampa-3]

Hello,

I succeeded now to start blip from inside eclipse as well, by simply
starting eclipse with preceded with LD_PRELOAD (+ first loading the
paths to where libjava.so and libjvm.so are located), like so:

export
LD_LIBRARY_PATH="/usr/lib/jvm/java-1.5.0-sun-1.5.0.19/jre/lib/i386/client/:/usr/lib/jvm/java-1.5.0-sun-1.5.0.19/jre/lib/i386"
LD_PRELOAD=/usr/local/lib/pl-5.7.15/lib/i686-linux/libjpl.so
/home/samuel/program/eclipse/eclipse &

Kind Regards
Samuel
