iODBC does not work under Mac OSX 10.6.4

Question

I've installed iODBC over the package (http://www.iodbc.org/dataspace/iodbc/wiki/iODBC/) and set up all config files as described here: http://blog.opensteam.net/past/2009/1/28/rails_ms_sql_on_mac/

I set up the same thing on a Linux machine and it worked fine. On my Mac OSX 10.6.4, I get this error if i test the connection:

xxx@xxx:/opt/local/include$ iodbctest "dsn=res;uid=user;pwd=pass"
iODBC Demonstration program
This program shows an interactive SQL processor
Driver Manager: 03.52.0709.0909
1: SQLDriverConnect = [iODBC][Driver Manager]dlopen(/opt/local/lib/libtdsodbc.so, 6): Symbol not found: _CreateDataSource
Referenced from: /usr/lib/libiodbcinst.2.dylib
Expected in: flat namespace
(0) SQLSTATE=00000
2: SQLDriverConnect = [iODBC][Driver Manager]Specified driver could not be loaded (0) SQLSTATE=IM003

I have no idea how to debug this :(

Hi

It would be interesting to see what params you have in your odbc.ini and odbcinst.ini files for the DSN and FreeTDS driver being used ?

Looks as if the Apple iODBC Driver Manager is not able to load setup routines required for the driver nor does the FreeTDS driver itself.

The OpenLink iODBC Driver Manager for Mac OS X (which Apples bundled one is based on) is Framework based and does include routines for loading generic setup and login dialogs for those ODBC drivers that do not have built in one. You can download it free (as it is open source) from the following location:
