Is there any way to have a spec file build an rpm for two separate
architectures with just the `rpmbuild -bb` command?

As an example, if I had a helloworld program written in C, and wanted it
to build on x86_64 on i386, how would I do that?

I figure in the build section I would have to build it twice with these
two commands:

  x86_64: gcc helloworld.c -o bin64/helloworld
  i386:   gcc -m32 helloworld.c -o bin32/helloworld

What I'm imagining is the build would take place, then the final lines
would look like:

Wrote: /home/build/rpm/RPMS/x86_64/helloworld-1.0-1.x86_64.rpm
Wrote: /home/build/rpm/RPMS/i386/helloworld-1.0-1.i386.rpm
Wrote: /home/build/rpm/RPMS/noarch/helloworld-docs-1.0-1.noarch.rpm

Any ideas on how to make this happen?



Add --target arch1,arch2,arch3,arch4

Note that these are sequential builds, not multiple arches in one build.

The design goal in rpm is
One value of arch is static throughout a build.


So, to repeat one of my questions from elsewhere on this branch: Does that mean there is no way to ask for more than one output architecture via spec file tags or macros instead of command line options? I wouldn't want those to give multiple archs in one build, either, but rather request multiple builds from within, of you know what I mean.
