It builds fine on RHEL 5 64-bit. Any ideas what the issue might be?

Thanks,
Dave

I just tried doing the same build with devtoolset 2 on 32-bit and ran into the same problem. Any ideas?
Thanks,
Dave

I did a little googling and found this: http://stackoverflow.com/questions/130740/link-error-when-compiling-gcc-atomic-operation-in-32-bit-mode

It looks like I need to build the .rpm with a flag that specifies a newer architecture than i386. Is that something I can/should put in the .spec file? Or is it just a flag that I need to pass when calling rpmbuild?

Thanks,
Dave
