How to enable GRASS plugin in QGIS 1.8.0 (Linux Mint 13 - 64 bit)?

Question

Every time I enable GRASS plugin in QGIS (Plugins -> Manage Plugins -> GRASS), I got a message: Exception - G_getenv(): Variable GISDBASE not set.
I googled and found some information here but don't know how to "unset GISRC".
Anyone please show me how to do it?

Answer 1

I solved it. I don't know if every step below is necessary but here's what I've done:

• Open the terminal and run GRASS from it.
• Create new Location and Mapset
• Import some data, save and quit.

Now I can open QGIS and enable GRASS plugin with no problem.
