Bug 306011 – revdep-rebuild --library libz.so.1 : issue wouldn't persist.

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Toralf Förster 2010-02-20 10:31:30 UTC]

Today I run "revdep-rebuild --library libjpeg.so.7" which runs fine, reemerged 34 packages and after that I run revdep-rebuild again and as expected no package to reemerge.
Therefore I'm wondering why this isn't true for libz.so.1 as mentioned within the forum thread.


Reproducible: Always

Uhm revdep-rebuild obviously won't and can't fix any -bin stuff. emerge chromium (not -bin) if you have problems.

I do not have installed chromium - and I don't plan to do it.

I read the forum thread (see URL) and I think this is probably an issue of revdep-rebuild which could be solved, isn't it ?

Because when you do 'emerge --library libjpeg.so.7' everything will be compiled against libjpeg.so.8 but when you do 'emerge --library libz.so.1' everything will be recompile against libz.so.1 again.

It's not a bug, it's a feature.

Ok - then bugzilla isn't the right place to ask - however I'm wondering about this :
If I ran "revdep-rebuild --library libjpeg.so.7" 2 times in a row - then the 2nd time the result set was empty (as expected).
Why isn't this the case for "revdep-rebuild --library libz.so" ?

I just explained it in Comment #3. The zlib's soname didn't change like jpeg's did. revdep-rebuild --library <something> will recompile everything that's using the given filename, even if there's nothing broken
