[ZOO-Discuss] Error when running GRASS processes

[Pierre Roudier]

Gerald, Soeren,

Many thanks for your answers.

I do make sure I'm running the latest svn updates of both ZOO and
wps-grass-bridge (I like the sound of a compiling machine in the
morning and it keeps my coffee cup warm ;).

Unfortunately, the apache log is not really verbose, only sasying that
the v_voronoi module is not found:

ImportError: No module named v_voronoi

I'm not too sure what you call process directory. Here is the content
of my /usr/lib/cgi-bin/
gms  HelloPy.zcfg  main.cfg  pywps.cgi  pywps_start  test_service.py
v_delaunay.zcfg  v_voronoi.zcfg  ZOOGrassModuleStarter.py
zoo_loader.cgi

the gms directory contains the following files:
ErrorHandler.py  GrassModuleStarter.py  GrassSettings.py  __init__.py
ParameterParser.py  ProcessLogging.py  Testing

I guess this is probably where I get it wrong, as the HelloWorld
module, independant from wps-grass-bridge, is working.

Yes, I noticed it - is it supposed to be launched from my server's shell?

Your help, and the efforts you are putting on open-source software,
is greatly appreciated.

Best,

Pierre
