Re: [GRASS-user] Grass7 GUI does not start

[ddarlac]

thanks, 
that helped a lot - wxgui is located in '/opt/grass/gui/wxpython'
running python wxgui.py is giving me
'segmentation fault'
running with sudo (although I have user ownership) I get the following:

Unable to import pyGRASS: grass_gis.7.0.3 not found.
Some functionality will be not accessible
NumPy not found.

This module requires the NumPy module, which could not be
imported.  It probably is not installed (it's not part of the
standard Python distribution). See the Numeric Python site
(http://numpy.scipy.org) for information on downloading source or
binaries.

I have numpy installed, maybe it cannot find it; but in anyway I do not
think this is the main problem
any help?

You can try to run the Python code directly. Somewhere in your installation
should be "gui/wxpython/wxgui.py". From GRASS command line run something
like:

python /usr/lib/grass70/gui/wxpython/wxgui.py

or you can try just:

python $GISBASE/gui/wxpython/wxgui.py

which is basically what g.gui does in the background.

You appear to be misunderstanding what "interactive" means in this
context. It doesn't necessarily imply a GUI.

The only situation where a script should be using d.mon is if it
really is a "script", in the sense of a canned sequence of commands
which is meant to be "replayed" as part of an interactive workflow.

Anything which tries to behave like a typical program should manage
the relevant environment variables directly.
