[GRASS-user] dbase driver in grass7

[Levente Juhász]

I was wondering about re-compiling GRASS7. I don't know if it is possible
to compile it with the dbf connection as default. I think that would solve
my problem. What do you think? Does it make any sense?
If so, can you point to a direction where I can start doing this?

Cheers,
Levente
