[gentoo-dev] rfc: jpeg upgrade news item

Samuli Suominen · External Since: Jun 02, 2009 Posts: 22

I've been asked to write a news item for jpeg upgrade by few developers.
Personally I don't see it's required, it's a default library upgrade,
but here's my attempt:

Title: Upgrade from media-libs/jpeg 6b to 7
Author: Samuli Suominen <ssuominen DeleteThis @gentoo.org>

Posted: 2009-09-22
Revision: 1
News-Item-Format: 1.0
Display-If-Installed: media-libs/jpeg

Since media-libs/jpeg-7 the .so version changed from libjpeg.so.62
to libjpeg.so.7. This will break temporarily a lot of packages,
including environments like Gnome, Xfce4 or KDE. You will need to run
revdep-rebuild from gentoolkit package.

Installing media-libs/jpeg-compat isn't the correct solution because
the package is meant to be used only with binary only applications like
games-strategy/savage2-bin where recompiling isn't an option.

You can temporarily install media-libs/jpeg-compat to get libjpeg.so.62
back so you'll be able to run applications again but it will most likely
cause you random crashing issues. [1].

For more information see [2] and [3].

I don't think that there should be a version restriction. People may
have upgraded but not have followed the advice in the news item.

If they had upgraded, they also probably have it fixed already.

So for everybody it's obvious how to fix it? If you argue like this,
then you don't need the news item at all. Wink
