[GRASS-user] trouble with addons - was: dilation & erosion (mathematical morphology)

[Robert Nuske]

Hi Paulo,

thanks for the hint!


Now I have some trouble to install the addon:

As a standard user I am not allowed to create a directory under /usr/lib.
A second try as root failed because HTML2MAN within "Grass.make" tries to call 
$(GISBASE)/tools/g.html2man.py. But the python script is called g.html2man.
After linking g.html2man.py to g.html2man the built of the addon fails because 
of a missing python module (ImportError: No module named html).


This was on ubuntu 14.04 with grass70 from the ppa:grass-devel. 
Version 7.0.0+1svn64464~ubuntu14.04.1 installed today.



Are addons supposed to be installed by standard users?


thanks 
  robert
