MarvinSketch 6.1 (64-bit) Won't Launch Java Class Loader?

Installed on 64-bit Kubuntu 13.04.  Tried to launch shell script for MarvinSketch64, but nothing happened; tried to launch msketch from /bin directory and got the following:

Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/david/.i4j_jres/1.6.0_41/lib/i386/xawt/libmawt.so: libXtst.so.6: cannot open shared object file: No such file or directory

Could not find the main class: chemaxon.marvin.Sketch.  Program will exit.

Any suggestions?

Thanks!

Hello David,

Thank you for reporting this. We will check this soon and get back to you.

Hello David,

Please run this command in a Konsole window:

sudo apt-get install ia32-libs-multiarch

This is a metapackage to install several 32bit compatible libraries, which need to run the helper JRE.
I think it will resolve your running problem.

Unfortunately I cannot reproduce this problem on a clean Kubuntu 13.04 64bit install and a marvinbeans-6.1.0-linux_with_jre64.sh file.

Thank you for your patience

I'm having the same problem as mentioned above. Ive noticed that the shortcuts work invoking dash:

/bin/sh "/home/myname/ChemAxon/etc...

but my invoking from the command line returns:

aiden@aiden-S301LA:/bin⟫ cxcalc

Exception in thread "main" java.lang.NoClassDefFoundError: chemaxon/marvin/Calculator

Dear Aiden,

  Can you try this command, and send us the output, if this fails?

/home/aiden/ChemAxon/JChem/bin/cxcalc

Can you send us the output of this command also?

echo $PATH

Thank you for your help

Arpad KISS

First command works

echo $PATH

/home/aiden/.i4j_jres/1.6.0_45/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

Thanks much!

Dear Aiden,

  Thank you for you answer.
From your command output it looks like the Jchem directories called bin and lib are out of sync. If you want to use
JChem commands anywhere, better choice is to insert the bin into the PATH environment variable.
For example you can insert this row into the end of your .bashrc file:

export PATH=$PATH:$HOME/ChemAxon/JChem/bin/

From the next login into your system you can use the JChem commands.

If you want to use Oracle Java 6 on your system, using original Oracle JRE/JDK is better instead of using JRE shipped with JChem.
You can install Oracle JDK/JRE with these commands:

sudo apt-add-repository ppa:webupd8team/java
sudo apt-get install oracle-java6-installer oracle-java6-set-default
