[GRASSLIST:1097] Re: Looking for a guru...

[Bill Dickinson Jr]

Thanks for all the replies. ;-)  It sounds to me like I should have 
been on this list months ago when I first started running into 
problems instead of trying to - stubbornly - figure it out myself. ;-)

I had not realized that GRASS does not need a database, so obviously 
my next step is to get GRASS running by itself and then potentially 
add the MySQL database support later on. Everything I had read gave 
the impression that you needed to have some form of database for 
GRASS to run properly, the recommended one being Postgresql. That's a 
little nugget of information that should be propogated better. ;-)

Thanks again. I will try GRASS by itself and see what happens.
