[ome-users] OMERO failing to build - java.lang.ClassNotFoundException: org.apache.tools.ant.util.regexp.Jdk14RegexpMatcher

[Bernhard Holländer]

Hi Renato!

AFAIK you don't have to build the python interface yourself. It comes
included in the release archive. The python packages and modules live
in /your_path_to_omero/lib/python. Put that path and the
path_to_Ice-3.3/python into the PYTHONPATH environment variable. This
should be enough to start coding against omero in python.

For example on linux (omero unpacked to /opt/omero-4.0.3 and Ice-3.3
installed in /opt/Ice-3.3) one could call python like this and import
the omero package:

$ PYTHONPATH=/opt/omero-4.0.3/lib/python:/opt/Ice-3.3/python python
>>> import  omero
...

See https://trac.openmicroscopy.org.uk/omero/wiki/OmeroPy for an
example how to get started.

Cheers! Bernhard
