[GRASS-dev] Re: raster modules still using sites library
I figured out what the 'problem' is with r.walk. If you use a null map for the friction map (because a friction map is required even if you don't want to use it), it creates raster support files but no map (i.e., no cell/fcell map). This is a minor bug as it should either give an error or create something (null map, ignore the friction map, but something). But it is an easy workaround and is not critical. Still, people should be aware of this. Michael __ C.

Hi Colin, It looks like this works fine with my system even though it is not working with another one. I suspect some local problem in that case. Michael C.
