/etc/odbcinst.ini used by 64 and 32 bits applications

I have the following /etc/odbcinst.ini file [root@]# cat /etc/odbcinst.ini [FreeTDS] Description=FreeTDS odbc driver #Driver=/usr/lib/libtdsodbc.so.0 Driver=/usr/lib64/libtdsodbc.so.0 UsageCount=1 I have applications compiled for 64 and 32 bits. [root@]# ldd prog_32 | grep odbc libodbc.so.2 => /lib/libodbc.so.2 (0xf7563000) [root@]# ldd prog_64 | grep odbc libodbc.so.2 => /lib64/libodbc.so.2 (0x00007f6087202000) As you probably noticed I have 2 entries in odbcinst.ini file for Driver, one for 32 bits and the other for 64. The problem is that if I run program compiled for 64 bits while the Driver is 32 bits or the other way around my program fails at run time with the error OTL error message = [unixODBC][Driver Manager]Can't open lib '/usr/lib/libtdsodbc.so.0' : file not found So I go and replace the Driver entry in the odbcinst.ini until next time it will happen to me which is quite frequent. Is there a way to use 64 bit drive for 64 bits applications and 32 bits driver for 32 bits application without needing to comment out the entry in the configuration file?
