Were you able to use macro detection to achieve this? I've done something similar by overriding the macros, e.g. via some "%global" statements. That's how I made packages.

I started out doing that, then I got more curious where %rhel was defined and why it wasn’t defined in Amazon Linux. This led me to /etc/rpm/macros.disttag, which on Amazon Linux has this:

# dist macros

     

%amzn               1

%dist          .amzn1

%amzn1             1

Based on that I was able to add if statements to, for instance, include the python27-devel package (on RHEL it’s just python-devel, so RHEL logic wasn’t directly applicable). Where I didn’t know the “right” answer, I just defaulted to adding conditionals to have amzn behave identically to RHEL 6 (no systemd, no Python 3, etc.)

With that I got a package build going of all the postgresql packages (libpq, contrib, etc. all included). If this is “standard” enough we [could] probably [… add these conditionals …] to the specfiles and add a buildfarm instance that just runs Amazon Linux in Docker and dumps the rpms to a shared volume for export.
