portage wants to re-emerge same packages everytime [SOLVED]

[Lebkoungcity]

Hello,

for some time now, some packages are being re-emerged over and over again on one of my systems. First I didn't mind because I thought this might be some kind of issue that will sort itself out when some specific package gets updated. But now it becomes an annoyance.

I use a chroot to build the packages for this system for it's an old ThinkPad with a Pentium-M and 2GB RAM but it's all the same on the ThinkPad and inside of the chroot. And the built binaries are never considered by portage, it wants to compile theses packages everytime anew. And: There is no error or other kind of failure.

My main question is: What is the root cause for this? How could I have found out what causes these rebuilds?

Here you see the ending of such an emerge and my usual habit of etc-update and emerge -a --depclean followed by another try if portage wants to re-emerge the packages it emerged successfully just a minute ago:

 * As a safety measure, depclean will not remove any packages

 * consequence of this, it often becomes necessary to run 
 * `emerge --update --newuse --deep @world` prior to depclean.

There are 3 backtracks. It's completely possible there are multiple ways around the issue and portage picking up different route on every sync, influenced by the changes in versions and so on.

What happens when you add --backtrack=0 to the command?

On a second note:

What is that? You have a 64 bit cpu but accepting x86 keyworded packages?

It's a chroot to build binaries for a x86-machine:

I use a chroot to build the packages for this system for it's an old ThinkPad with a Pentium-M and 2GB RAM but it's all the same on the ThinkPad and inside of the chroot.

Probably same as http://forums.gentoo.org/viewtopic-t-1177060.html ?
(and https://bugs.gentoo.org/969654 )

I don't see them either just because there aren't any. No failures, nothing. So I suspect this is the same thing but I don't know. Therefore I'm asking for help here. And: How should I find out which package causes this re-emerge-loop?

[logrusx]

If it didn't break with backtrack=0 then your issue is resolved for the time being. Did you let those packages rebuild before posting that output? If so, post it again when other rebuilds appear, before rebuilding them.

Best Regards,
Georgi

[Lebkoungcity]

Thanks for you input. But I can't consider this as resolved because:
a) I have no idea what caused this re-emerge-loop and have no idea on how to resolve this thoroughly and not just a symptom. I'm one of those weird kind of people who want to understand the causes.

My main question is: What is the root cause for this? How could I have found out what causes these rebuilds?

b) Because this chroot is used to build binaries for a somewhat underpowered system (measured by today's requirements) and in this special case the built binaries of these packages in question aren't considered by portage, I would need to compile boost and nodejs on this x86-system meaning quite some hours of compile time. Which is something I would rather avoid.

And the built binaries are never considered by portage, it wants to compile theses packages everytime anew.

edit:
Forgot one answer:

Did you let those packages rebuild before posting that output?

No, I didn't.

[logrusx]

Dies the original command still want to rebuild then?

Yes, it does:

Sam thinks it's the same bug referenced above. Could you please try with portage-9999?

Best Regards,

[Lebkoungcity]

OK, that's it!

I emerged sys-apps/portage-9999 and then executed the known emerge -tauvDNUk world --keep-going --with-bdeps=y but a problem with x11-themes/qtcurve became visible. After removing x11-themes/qtcurve I was able to give emerge -tauvDNUk world --keep-going --with-bdeps=y another try and it showed a clean output.
