[GRASS-user] Running grass in virtualbox with shared folders

GRASS GRASS user
1

Hi all

I'm running grass7 in virtual box (tried both ubuntu mate and mint linux)
and trying to open a location/mapset located on a mounted shared folder.
Write permissions appear to work in the file browser, but I get an error
(pasted below) trying to start the grass gui. Any thoughts on how to fix?

THX

Launching <wxpython> GUI in the background, please wait...

Linux guest or host? What is the other OS? Or both Linux?

I've run GRASS in a linux guest on an OS X host. I had to use "sudo" when
accessing the OS X host.

  -k.

Linux VM, OSX Host. Shared folder work within the regular file system
operations, but not for running Grass locations.

Do you mean that you had to start grass with "sudo grass"?

Ah yes - that works! Thanks! Wonder why I can't access as my regular user?

On Linux one has to be member of the group "vboxusers", perhaps also on Mac?
