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 as standard user: ----------------------------------------------------------- GRASS 7.0.0 (wgs84):~ > g.extension extension=r.grow.shrink svnurl=http://svn.osgeo.org/grass/grass-addons/grass7 --verbose Fetching <r.grow.shrink> from GRASS-Addons SVN repository (be patient)...
