I have been working for the better part of a year on moving Fedora
off
of libpng's obsolete 1.2.x release series and onto the current 1.5.x
series. We are practically there now, and I had hoped to drop libpng
1.2 from the distribution before the F18 branch. However, I find that
redhat-lsb-desktop still has a dependency on 1.2, and it's not even
because that package contains any PNG-using code; rather, there's a
manually inserted version-specific dependency in the specfile:
%ifarch %{ix86}
Requires: libpng12.so.0
%endif
%ifarch x86_64
Requires: libpng12.so.0()(64bit)
%endif
This is unlike that specfile's treatment of any other library
it requires. I have been told, at
https://bugzilla.redhat.com/show_bug.cgi?id=835777#c8
that the LSB standard requires libpng 1.2, but without any supporting
evidence. I looked at the underlying ISO documents and don't see any
requirement for libpng at all, let alone 1.2 in particular. I am
doubtful that every other Linux distro is maintaining this long-obsolete
libpng version, too.
I would like to know how to proceed here. "You should keep libpng 1.2
around indefinitely, on the basis of no evidence" is not an answer
I intend to accept.
in the 'desktop' section of LSB 4.1. I'm looking at it more closely now.
