Re: trouble getting kissme to work with gcp

Giannis,

First, this email would be better directed to the kissme mailing list:

        address@hidden

I've cc'ed that list.  If you reply to this email, please remove 
address@hidden from the cc: list.

Your best bet for getting Kissme to work is to read the kissme/docs/
BUILDING file carefully, and follow the instructions therein.  I've
also included some hints below.

It is not necessary to give "--with-java=kissme" or "--with-classpath"
when configuring Classpath.  I'd remove them because they >>might<<
cause problems.

We (the kissme developers) haven't put any of the kissme-specific java
code into the Classpath tree.  The Classpath build and install process
doesn't need to know anything about Kissme.

That should be OK.  The kissme configure script should give you an error
if it can't find the installed Classpath jar file and shared libraries.

That makes sense.  Your effective classpath should look like this: 

  .../kissme/classes.zip:.../glibj.jar:..../kissme

i.e. classes.zip file MUST be before glibj.jar in the effective classpath.

It looks like the kissme jvm is not picking up the Classpath shared libraries.  
You probably need to add the directory wher the libs are installed to
the LD_LIBRARY_PATH environment variable.

See the hints above, and read the Kissme BUILDING document. 

Also try using the 'kissme' wrapper script in 'useful_scripts' to run
the 'helloworld' program.  The wrapper prepends the correct stuff to the
effective classpath, and sets LD_LIBRARY_PATH as required.
