scilab java

[e-letter]

Readers,

Below are command terminal errors trying to install scilab 5 and run
in opensuse:

scilab
/usr/bin/scilab-bin: error while loading shared libraries:
libhdf5.so.6: cannot open shared object file: No such file or
directory
[root] # rpm -i libhdf5-0-1.8.2-2.2.i586.rpm
warning: libhdf5-0-1.8.2-2.2.i586.rpm: Header V3 DSA/SHA1 Signature,
key ID bd432934: NOKEY
[normaluser] # scilab
Warning: Could not find Java package '/usr/lib/java//jhdf5.jar'.
Some problems during the loading of the Java libraries occured.
This could lead to inconsistent behaviours.
Please check SCI/etc/classpath.xml.
Error parsing gtk-icon-sizes string: ''

If scilab 5 requires java, why is it not compiled as a jar file? It is
too difficult to configure. Programmers should consider that other
java software would be installed before scilab.
