Surfex help

I have got surfex and it works outside Singular but does not work inside singular. The singular functions in surfex.lib that use surfex don't work, for example plotRot(), plotRotatedList(), etc. However, the functions in the library surf.lib DO work fine. When I run something in surfex.lib I get no error messages. It just gives me another command prompt and does nothing else.
Any suggestions to help get surfex.lib working would be appreciated.

Another Question,
There is a version of Singular available for Windows called Singular-3-0-4-Full.exe that comes with surf,surfex and more all precompiled and ready to use in singular.
Is there something similar available for linux?

To your first question:
surfex is a shell script which collects all needed data
and then calls java with the right arguments.
Singular uses (in addition to the original surfe/x)
the first argument as working directory, i.e.
you should make sure that you call the script surfex which comes
which Singular. To test with, try within Singular
system("sh","which surfex");
or
system("sh",type -p surfex");

Second question: binary package for Linux:
There is no single complet package (too many distributions out there),
but you may try:
-ftp://www.mathematik.uni-kl.de/pub/Math/Singular/UNIX/surf-1.0.2-ix86-Linux.tar.gz
(binary package for surf, to be installed like the other packages
for Singular described at
http://www.singular.uni-kl.de/UNIX/generic_install.html
)
- surfex needs surf and java, everything else is already included in
Singular (more precisely, in Singular-3-0-4-share.tar.gz)
