Hello All!
One of my packages defines an essential information regarding the API (API version string) during the %build stage. It's possible to extract this information by invoking a binary from the %{buildroot} with certain parameters. I'd love to add this information to the spec-file during to Provides. Something like
Provides: %{name}_api_ver = %(%{buildroot}/bin/app --some params)
Unfortunately it seems that rpmbuild tries to expand all macros at the very initial stage when this binary isn't available yet (not built yet). I've tied playing with %{eval: ...} but without any luck.
Could anyone tell me if it's possible at all? And if possible how could this be achieved?
Also I wonder why even rpmbuild -bs performs macro expansion? I thought it should just pack spec-file and sources/patches together.
