How do I find a dependency's dependency?

audiodef

Advice would be greatly appreciated. I don't know much about scons or how to fix scons issues.

Just for reference, but doesn't mention anything to help.

I think I need to track down what is requiring the ~arch version of scons and deal with that.

I'm actually trying to troubleshoot my Gentoo Studio stage4 catalyst build.

It occurred to me to look at the available versions of ~arch scons and start by masking the highest one. If that helps, great, but I'm not happy that a package somewhere is demaning ~arch scons. It shouldn't be needed for this build.

EDIT: WTF? Something is asking for scons-3.0.1-r100, so masking is not helping.

You have qdepends -Q that could answer that, the weakness is that it will only answer if the relation already exists (only if scons is install, and someone do depends on it)

With a few logic, you might also find it who:
scons is ~
if you consider that gentoo devs strictly make stable package using stable dep, this mean that only an ~ package would ask a ~scons.
so because you are running stable, culprit you seek must be an ~ package

If something in this list is demanding the latest ~arch version of scons, how do I find out without taking two weeks off to manually dig through it?

The weird thing is, this is not an issue on any of my actual, used IRL Gentoo Studio machines when I update them. And if it's installed in the tarball, it's installed on my existing machines. (Well, except for scons-3, of course. Scons-2 is being used on existing machines, nothing wants to ~arch that.)

Hm, yeah, I could put that list in the world file on a test VM and do that. Thanks for the idea.

What I don't understand is, why libffado is marked as stable on your system?
On my amd64 stable I have

eix libffado

Hi,

did you find a solution to this problem?
I have exactly the same issue.

If you use python 3.6, libffado will depend on =dev-util/scons-3.0.1-r100 ~amd64

I found a workaround for now:
create a file: /etc/portage/package.use/libffado

I'll try that first. Thanks, krinn and khay.

sebB, it's not stable on my system. It still has to go in accept_keywords. Yes, it needs scons but it does not need ~arch scons, which is buggy.

Ok, so the problem is python3.
dev-util/scons-3.0.1-r100 introduce python3 target.

If python3 is enabled, for libffado, it pull scons unstable

try this in your package.use

Thanks, sebB. Hu mentioned something along these lines. I'm going to try your suggestion.

This worked, and prevented scons-3 from being called in. I added python 3_4 and 3_5 to this line to make it work.

It seems I inadvertently created two posts on the same topic without realizing it. Moderators, feel free to merge. I don't care which one is merged into which.

The other topic: https://forums.gentoo.org/viewtopic-t-1082914-highlight-.html

This is exactly how I solved it, upon advice from sebB in another thread.
