Bug 367933 – sys-apps/portage-2.2: odd "library needed" detection logic (WAS:chromium-11.0.696.68 is a dependency for a lot of packages requiring ffmpeg libraries)

• Product: Portage Development
• Status: RESOLVED FIXED

[Description Andrea Franceschini 2011-05-18 16:42:53 UTC]

As already reported at https://forums.gentoo.org/viewtopic-p-6689965.html I'm having this weird behaviour.

[Comment 1 Jeremy Olexa (darkside) (RETIRED) 2011-05-18 16:54:37 UTC]

That output looks surprisingly odd. My first impression is a portage bug.

% qlist ffmpeg|grep libavcodec.so.52
/usr/lib64/libavcodec.so.52.96.0
/usr/lib64/libavcodec.so.52
% qlist chromium|grep libavcodec.so.52
/usr/lib64/chromium-browser/libavcodec.so.52

So, I highly doubt that the packages *really* need /usr/lib64/chromium-browser/libavcodec.so.52 instead of /usr/lib64/libavcodec.so.52

Anyway, I can't reproduce with ~arch portage. :(

[Comment 2 Andrea Franceschini 2011-05-18 17:03:36 UTC]

(In reply to comment #1)

I can confirm that I get quite a similar output:

$ qlist ffmpeg|grep libavcodec.so.52
/usr/lib/libavcodec.so.52
/usr/lib/libavcodec.so.52.117.0

$ qlist chromium|grep libavcodec.so.52
/usr/lib/chromium-browser/libavcodec.so.52

[Comment 3 Jeremy Olexa (darkside) (RETIRED) 2011-05-18 17:07:14 UTC]

What about "ldd" on some binaries that portage claim need chromium? Can you prove or disprove that portage is correct/incorrect?

$ ldd /usr/bin/blender
[...]
        libavformat.so.52 => /usr/lib/libavformat.so.52 (0xb72b6000)
        libavcodec.so.52 => /usr/lib/libavcodec.so.52 (0xb6781000)
[...]

Here's just (possibly part of) the relevant output. I think Portage is incorrect.

[Comment 5 Zac Medico 2011-05-18 18:14:52 UTC]

Please try to reproduce with portage-2.2.0_alpha34, since it has lots of preserve-libs fixes, including bug 286714.

This effectively solved the problem, thanks.
