Red Hat Bugzilla – Bug 67007
libpng has file libpng.so.3, but doesn't "Provide:" it
Last modified: 2013-04-02 00:16:18 EDT
Description of Problem: Installing a newer version of libpng(12), while having older packages which requires libpng.so.3, rpm refuses to install it (without --nodeps). This is despite the fact that the new libpng12 RPM has a file libpng.so.3 which is a symlink to the newly named libpng12.so.0. Version-Release number of selected component (if applicable): libpng-1.2.2-5 How Reproducible: Always when not doing a full RawHide update, but just of libpng Steps to Reproduce: 1. iInstall older packages relying on libpng.so.3 2. Try to install libpng-1.2.2-5 Actual Results: Fails due to dependencies (requirement of libpng.so.3 Expected Results: Successfully install without warning or error. Additional Information: It's a simple problem: libpng.so.3 is provided as backward compatibility to the "old" naming scheme, which has been replaced by libpng12.so.0. The provided symlink is not recognized by "find-provides" (which checks sonames only, obviously). All you need is a line "Provides: libpng.so.3" as long as this symlink is being delivered. I had (would've had) to rebuild quite a few packages (of my own) to fix this dependency, despite the delivered backward compat symlink.
Oh, this is a bit of a dupe of bug #64646, by the way.

Nice try, marking as duplicate but solving only the wrong part of the dupe. ;-) "libpng.so.3" is still not provided by the package, despite its symlink being delivered. Though I know that "libpng12.so.0" is the new naming scheme used by most distributions, this still breaks legacy packages requiring "libpng.so.3". I'd like to reopen this bug, but can't (haven't got my old account's password handy right now, and can't have one mailed there either. ;->) (In the dupe, only the old gcc2.96 naming scheme was fixed, AFAICT.) Thanks for listening, Moritz
Whoops. Didn't read it carefully enough. Sorry about that.
Alright. Now it's fixed in rawhide. (-;
