Re: [Help-glpk] JNI

[Yuri]

Hi Welson,

Two things that are a must in general
for any JNI to be installed:

* .jar file should get to directory where
  all other .jar filrs are
  (usually $JAVE_HOME/jre/lib/ext)
* native lib (.so) file should get where
  JVM is looking for them
  (usually $JAVA_HOME/jre/lib/i386)

I believe if you make sure both these files
compiled by you are there it should work.

Yes JNI works on Linux.

Regards,
Yuri
