Re: [fedora-java] Dealing with LD_LIBRARY_PATH for a package using JNI

I'm currently working on enabling the "jpl" Java

Prolog (package is called "pl" in Fedora). This provides a
bidirectional interface between Prolog and Java -- you can call Prolog
from Java or (what I'm doing in my current project) call Java from
Prolog.
I'm attempting to follow the Java packaging guidelines for JNI-using
projects and putting jpl.jar and libjpl.so into $LIBDIR/pl-jpl and
patching files so that the libraries get loaded, and that's going
well.
One thing I'm not sure how to deal with: libjpl.so is linked against
libjava.so and libjvm.so. On my machine, that means I need to set
LD_LIBRARY_PATH to
/usr/lib/jvm/java/jre/lib/i386:/usr/lib/jvm/java/jre/lib/i386/client
before I run Prolog, and the same is probably the case if I wanted to
use the Java-to-Prolog direction.
The command-line program 'java' already sets its LD_LIBRARY_PATH, so
it shouldn't be necessary when calling from Java.
