Before you begin your installation, verify that unixODBC is not already installed on your machine. If it is, uninstall the existing version of unixODBC.
Installing and configuring FreeTDS
Download FreeTDS from the FreeTDS Web page, and unzip the source code. Sybase recommends that you use the latest version of FreeTDS, which is fully compatible with ODBC 3.0.
Change to the FreeTDS source code directory; for example, /usr/tmp, and run:
./configure --prefix=$DJC_HOME/freetds \ --with-tdsver=5.0\ --with-unixodbc=$DJC_HOME/odbc
Compile the source code:
make make install
The compilation process adds the library libtdsodbc.so to $DJC_HOME/freetds/lib.
