thanks for the reply.The application code was compiled on 64 bit machine
with -m64 flag.And the DM was mysql connector driver which was 64 bit binary
and odbc driver was compiled on the 64 bit machine.Apart from this i have
one more query.
Is their any option(compilation flag which can be set) for compiling odbc
driver with 32 bit compilation on 64 bit machine.
