In regard to: RE: single RPM for all distros?, Heyman, Jerrold said (at...:
Yes, the original request was for a binary RPM.
Specifically, we are leveraging libfuse
SLES packages as libfuse2, RHEL packages as fuse-libs, Mageia as lib64fuse2, ...
A single way to write the 'Requires:' directive would be my holy grail.
If those 3 distributions don't provide the same SONAME for the
library/libraries you're linking against, then short of using a shim
and loading the libraries under different names, there is no one Requires
that's going to make your application work.
If they *do* provide the necessary library or libraries, with each
distribution having the same SONAME for the corresponding library,
then it's likely pointless to even specify Requires. You may want
to specify BuildRequires so the right packages (per distro) are pulled
in at build time, but in this case you wouldn't need Requires.
Do this: on each distribution and version you care about supporting, run
rpm -q --provides <whatever the distro calls the fuse package here>
e.g. on RHEL it would be
rpm -q --provides fuse-libs
Then respond with the output, broken out by distro & version, so we can
see what's provided by each of the distro/version combos you care about.
That will make it clear whether what you're trying to do is even possible.

if find-requires provides the correct libs, you might use 'Autoreq:

See http://www.rpm.org/max-rpm-snapshot/s1-rpm-depend-auto-depend.html
On rhel, find-requires path is at
/usr/lib/rpm/find-requires
Otherwise, you can write conditional anything, e.g.,
%if 0%{?fedora} >= 18 || 0%{?rhel} >= 7 %ifarch %{arm}
Requires: glibc >= 2.16
%endif
%endif
Those provide for a single SRPM that compiles on multiple distros.
That is good, and standard practice, but I think the OP was asking if there was a way for a single *binary* RPM to
install on multiple distros. Of course there is, but what I've seen from proprietary vendors has been rather ugly -
usually a combination of static linking and lengthy %pre/%post scripts that make me afraid to install the package.
