Bug 601326 – www-client/firefox-50 should not depend on x11-libs/gtk+:2

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description fkater 2016-12-01 08:39:45 UTC]

Situation: I've compiled firefox-50 on arm64 against gtk+:3. I don't even have
gtk+:2 on my system. Firefox works fine.

Problem: When resolving world package dependencies in depth, portage wants me
to install gtk+:2 for firefox.

Workaround for me (I am using paludis/cave):

* Open the two files /var/db/pkg/www-client/firefox-50.0.1/DEPEND and RDEPEND

* Change ">=x11-libs/gtk+-2.18:2" into ">=x11-libs/gtk+-2.18"

Remarks: I don't fully understand the firefox ebuild. But IMHO the firefox
installation somehow marks itself still dependent on gtk+:2.

    mozconfig-v6.49.eclass: Make dependency on gtk+:2 optional (bug #601326).

Thanks for the fast reply.

I just tried firefox-50.0.2 but got this. Not sure if this is related to
the above fix or something else, though.

So all Poly-C's patch did was remove the RDEPEND on gtk+:2 which allows you to install it if the build system didn't actually need it.  The problem is, I am still fairly certain that there are components within the firefox codebase that do still need gtk+:2.  This may change in firefox-53 and above, but for now, I believe that it is indeed still a requirement even when cairo-gtk3 is the toolkit requested.

I'm going to revert this commit until such time as gtk3-only builds can be ensured.

What's the status on this? Why are current firefox ebuilds not depending on gtk+:2?  The dependencies should reflect what's actually required, not what you wish was required =)

Dependencies have been added back.

So firefox etc will continue to depend on gtk+:2 until such time as flash support is dropped; although npapi plugins in general are banned, the functionality is still there to support flash and so the dep is still required.

If you feel I have closed your bug and it is still a current issue, please reopen and update it completely. We will not work bugs that have no ebuild in tree any longer or can not be reproduced with a current system.
