For some virt packages we need to combine 2 or 3 of:
ExclusiveArch: %{kernel_arches}
ExclusiveArch: %{qemu_sysemu_host_arches} # [1]
ExclusiveArch: %{ocaml_native_compiler}
to mean only compile on the intersection of these arches. If you have
multiple ExclusiveArch lines then RPM seems to do the union of arches
which is the opposite of what anyone would want.
Dan Berrange came up with a clever way to do it though ...
%ifnarch %{kernel_arches}
ExcludeArch: %{_arch}
%endif
%ifnarch %{qemu_sysemu_host_arches}
ExcludeArch: %{_arch}
%endif
But this makes my head hurt. Is there a better way or could RPM
provide explicit union and intersection operators?
Rich.
