Yes, thank you for the library-dependency background info. I'm a developer
and have some experience in this topic.
What I do not know: how much work does the Fedora community do to ensure
that the libraries for new FedoraCore platforms are backwards compatible
with old ones?
I am building software to target all the Fedora platforms (from FC1 through
FC4...or any new ones that come out), and I'd prefer that I build one
binary for all four (currently) of the FedoraCore platforms for the
i386/i686 base...and not have to setup and run 4 different Fedora build
machines in my "build farm" (from which I'm also building Windows, RHEL,
Debian, and probably FreeBSD flavors of my software as well).
As side note: are i386/i686 essentially the same binary? Or should I be
careful to binary-distribution-config control (and differentiate between)
these 2 flavors (i386 and i686)?
To be clear: I'm not worried about .rpm packages for now. I'm just talking
about the binary-application dependence, and therefore the conversation
probably becomes mostly a library-dependence conversation.
I am building exclusively C++-based code using the g++ toolset that comes
with whatever Fedora machine I build from, and I can update the g++ toolset
as need be.
