Hello,
I have a requirement to generate a dll which can run on both 32 bit
and 64 bit Windows OS.
Is there any option/way in gcc to do this?
Thanks,
Rama.

Just build your dll with a 32-bit build of gcc, and it will run on 64-bit
Windows OS (unless the app that tries to load that dll on the 64-bit OS was
built as a 64-bit app.)
That is, 32-bit apps/dlls will run on both 32-bit and 64-bit Windows OS.
Cheers,
Rob

Can't you just use a 32-bit DLL? Then both 32-bit and 64-bit apps can
access it. If the same file has to work on two platforms, you have to
code for the lowest common denominator.

If by "64-bit apps" you mean apps that were built using a 64-bit compiler,
then they cannot access a 32-bit dll (unless I'm mistaken ... which has been
known to happen).
But if by "64-bit apps" you mean apps built by a 32-bit compiler but running
on a 64-bit Windows OS, then we're in agreement.
Cheers,
Rob
