I think you will have better luck posting directly to the ODBC newsgroup:
news://forums.sybase.com:119/sybase.public.connectivity.odbc
But to get you started off, with 12.5.1 there are two sets of drivers provided:
1) Drivers manufactured by DataDirect
* Located in c:\sybase\ODBC
2) Drivers manufactured by Sybase
* Located in c:\sybase\DataAccess
It is recommended that you use the drivers manufactured by Sybase because
in version 15.0 we will only provide those drivers and it will make migrating
to 15 that much easier.
The ODBC Drivers need various stored procedures installed to help describe
meta-data. Look in the following directory for a script called
"install_odbc_sprocs.bat" and run it against your target server to install
the required stored procedures:
USAGE :install_odbc_sprocs myaseserver login1 pass1
Directory of C:\sybase\DataAccess\ODBC\sp
