Hi all,
When i use a parameter to assign the output map name of r.mapcalc in GRASS7
for windows, it gives an error message saying:
Command 'd.rast map=viewshed2@PERMANENT' failed
Details: Unknown display driver <cairo>
routput is a parameter set by options (routput = options['routput'])
grass.mapcalc("routput = viewshed + 1", overwrite = True, quiet = True)
However, when i just assign a name for the map without a parameter the
output writes in the current MAPSET.
Here, viewshed1 is the new map after r.mapcalc operation
grass.mapcalc("viewshed1 = viewshed + 1", overwrite = True, quiet = True)
What is the cause for this?
