bug#25484: QEMU depends on two different version of libjpeg

[Ludovic Courtès]

While building ‘qemu’ as of 840f38ba37af1d09eb1e896a6350d6ab7f6532d0, we
see:

--8<---------------cut here---------------start------------->8---
ld: warning: libjpeg.so.62, needed by /gnu/store/9a3r8wjnfyxfc912i6inlw8k6pw3rlxy-spice-0.12.8/lib/libspice-server.so, may conflict with libjpeg.so.8
--8<---------------cut here---------------end--------------->8---

Indeed, ‘guix graph -t references qemu’ shows ‘libjpeg’ and
‘libjpeg-turbo’ as indirect dependencies.

Any idea how to fix that?

Thanks,
Ludo’.

“libjpeg-turbo” is used by “spice” but I just built “spice” successfully
with “libjpeg-8” instead of “libjpeg-turbo”.  This seems to be okay.

Attached is a patch.  I successfully built “spice” and “qemu” and
confirmed with “guix graph -t references qemu -b d3js > graph.html” that
libjpeg-turbo has disappeared.

LGTM.  David: are you OK with this change?

Thanks for the quick testing, Ricardo!

Hello Guix,

I think this 3 year old bug is fixed, even though Ricardo's patch wasn't
applied. I can't find any “may conflict with “ in the build log of a 
recent
build of qemu[0] and qemu now depends on 'libjpeg-turbo' instead of
'libjpeg' since 513885b54e5a6abd46cb02b04ebab51b879150c0.

Should we close this issue?

Indeed.  On the 'core-updates' branch, _all_ packages are now using
exclusively libjpeg-turbo.

Yup, done with this message.

Thanks for helping out with bug triage!
