Dear Moritz and all Thank you for useful advices !
Method [2] succeeded. However, the resolution should be small, and it devise it a little more. Method [3] failed in the installation. I have improved two files --Module.make, Grass.make-- referring to a past log. However, the installation failed with the following message; /usr/bin/install -c /usr/lib/grass64 /bin/d.barb /usr/lib/grass64/bin/ Best Yasuo shimada ---------- > Use icon= for defining a symbol (see [1] for examples). > > But you might be better off using a raster approach and d.rast.arrow. > See example at [2]. > > Or check out Hamish' d.barb AddOn module [3]. > > Moritz > > [1] http://grass.osgeo.org/wiki/IconSymbols > [2] http://grass.osgeo.org/wiki/Meteorology > [3] http://grass.osgeo.org/wiki/GRASS_AddOns#d.barb I tried [2] and [3].
