[GRASS-user] r.roughness needs bc

[Manuel Seeger]

Hello all,


I'm trying to use r.roughness on windows vista, built from the osgeo4w.

Unfortunately we get the following message:


./r.roughness map=Rough3 grid=0.03 rough=Rough3.roughness.3
/which: bc: unknown command
r.roughness: bc required, please install it first/

/
/

/What is bc?/

/Where can I get this?/

/
/

/best regards!/

/
/

/Manuel/
