[unixODBC-support] basic config questions

[Rick Schumeyer]

I'm trying to (eventually) connect a ruby-on-rails program to SQL
Server.  I'm running CentOS 5.2.  I installed unixODBC and FreeTDS
from source in the default location (/usr/local).

The FreeTDS part seems to be working.  The command "tsql -S eeyoredb
-U xxx -P xxx" is successful.

But I cannot get the unixODBC part to work.  I always get
"Data source name not found, and no default driver specified"

I have tried many things suggested by several google searches, but no success.

Can I create the odbc.ini and odbcinst.ini files in /usr/local/etc
using a text editor?  Or do I need to use the odbcinst program?  (I'm
not really sure what that does)

The current state of my odbc.ini and odbcinst.ini files are below.

Then I try isql:

[rick at buster ~]$ isql -v sqlserver
[IM002][unixODBC][Driver Manager]Data source name not found, and no
default driver specified
[ISQL]ERROR: Could not SQLConnect

I'm really lost.

I checked, and the shared library files are really in /usr/local/lib.
