Hi
Is there a way to determine the arch of the rpm being created by rpmbuild, other than looking at the output for the following lines:
Wrote: /home/build/redhat/SRPMS/pkg-1.1-0.src.rpm Wrote: /home/build/redhat/RPMS/ia64/pkg-1.1-0.ia64.rpm
You mean inside specfile? %{_arch} contains it, eg in above case 'ia64'.

I am more interested into the supported arch that the rpmbuild on a specified platform. The rpmbuild --showrc does show the build arch but is there a more programatic way to get the suppoerted build arc?
If possible, would it be possible to detect the arch of the rpm being created?
I'm not quite sure what you mean here... You can't reliably know what a given rpmbuild command is doing outside the build process itself, meaning the specfile where the target architecture is in %{_arch} macro.
'rpm --eval "%{_arch}"' gives you the default architecture of the system and you can ask a specfile for it's BuildArchitecture with
'rpm -q --specfile --qf "%{arch}\n" foo.spec' but that doesn't tell you how an rpmbuild command was started, eg with --target i686,athlon.
If that doesn't answer your question then explaining what you're actually trying to do might help producing a more useful answer.

Hi
Thanks for your help. I was looking for a way to get the arch of the rpm before it was being built. rpm -q --specfile --qf "%{arch}\n" specfile will work in my situtation because it is part of my build system that controls how the rpm is being built.
Thanks, Liming
