The check for this needs to be careful. When some requirements are
missing a build can still succeed, but be missing intended features. So
you can't just test whether a build succeeds or fails to determine if a
build requirement is really needed.
Yep. I remember back when we did the s390x stuff for F12 that was one of
the things we looked at specifically: Hacking things together to get at
least building was a good start, but if you didn't install several other
packages the build would still succeed but with autoconf automatically
disabling several features.
Thats why i really like the way we've moved over the past 10 years or so
to explicitly only have a pretty small buildsys environment and almost
everything else needs to be explicitly required for building from the
respective packages.
Famous last words: Can't be that hard to write a script that compares 2
builds that they provide the have the same provides and requires and
filelists. :)
Thanks & regards, Phil
