Hi,

Can you please tell me can I use gcc 3.4 to compile a binary on a 64
bits machine? or I need to use gcc 4.1? I am running Red Hat
Enterprise Linux 4 and it comes with a gcc 3.4. Can I just use that to
compile a 64 bits binaries?

Thank you.

Yes, gcc-3.4, on x86-64, builds 64-bit programs. The x86-64 installation of either version of gcc requires the option -m32 (and the corresponding additional installed components) to build 32-bit binaries.
