[ome-devel] Scripts / Environment Variables / OpenGL...

[Josh Moore]

Hi Jerome,

The entire environment from the running user is not copied into the subprocess. If you would like to workaround for the moment see:
https://trac.openmicroscopy.org.uk/omero/browser/ome.git/components/tools/OmeroPy/src/omero/processor.py#L127
We can discuss the implementation under:
http://trac.openmicroscopy.org.uk/omero/ticket/4027

Cheers,
~Josh
