Hy Leo,
I tried what you told me about the ld.so and ldconfig, but it doesn't work nether...
I have still the same error!

I'm assuming that you mean the *module* is an extension library (i.e. a
.so file that is imported by your python code) and the *library* is
another .so that is needed by that module. In this case, the module must
be in the PYTHONPATH just as I mentioned, but the library must be in
your machine dynamic linker path. Take a look at the ld.so man page
("man ld.so") and, if your machine runs Linux, at the file
/etc/ld.so.conf and the ldconfig man page ("man ldconfig"). You may need
to configure the LD_LIBRARY_PATH environment variable.
Cheers, Leo

What's wrong with twiddling PYTHONPATH? My instance home has a 'Packages' directory, where I have stuff like _ldapmodule.so (for ZLDAP), imaging.so, and the PIL and ldap packages. My start script looks like this: #!/bin/sh PYTHON_VER=2.1.3 ZOPE_VER=2.5.1 INSTANCE_HOME=/zope PYTHONPATH=$INSTANCE_HOME/Packages export INSTANCE_HOME PYTHONPATH STUPID_LOG_FILE=$INSTANCE_HOME/var/log/zlog_`date +%Y%m%d`.log STUPID_LOG_SEVERITY=-200 export STUPID_LOG_FILE STUPID_LOG_SEVERITY echo `date` starting >> $INSTANCE_HOME/var/log/start_`date +%Y%m%d`.log exec $INSTANCE_HOME/Python-$PYTHON_VER/bin/python2.1 \ $INSTANCE_HOME/Zope-$ZOPE_VER/z2.py \ -F $INSTANCE_HOME/var/FastCGI.soc -m 8099 -p - "$@" \ >> $INSTANCE_HOME/var/log/start_`date +%Y%m%d`.log 2>&1 All in all, it works pretty well. No need to sweat messing with PYTHONPATH. All instance homes should do this, and have a Packages directory :-) ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

The usual place is /lib/python2.1/site-packages Putting it in the Extesions directory, so that it can be imported by external methods, doesn't seem to work, even if you put Extensions in the PYTHONPATH, at least in my experience. -- Ideas don't stay in some minds very long because they don't like solitary confinement. ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
