Hello

After a main HD failure, I'll have to reinstall Gentoo from almost zero - I have a full and recent copy of the /etc directory and the file /var/lib/portage/world in a secondary HD (along many personal backups).

Installation basics done, now it is time for an emerge world.

Although the emerge lists is as huge as expected, it doesn't even start, portage says there are cyclic USE flags that I should avoid at the first moment, but may restore afterwards.

But it doesn't say which are those USE flags that block each other.

Is there any way to find those better than brute force?

By the way, I also have a copy of all binary packages (I always use the -b
flag while emerging any package) in that second disk. But that didn't help
so far, even trying to use the -K flag. I thought on un-tar'ing those
binary packages by hand, but portage will be unaware of this, not knowing
the packages are installed.

Any hint will be greatly appreciated!

Thanks

Francisco

Try emerging @system first and see if this succeeds. I recall something similar on a recent fresh (re)installation, but the USE flags causing the circular block were reported in the emerge output, so I was able to unset and reset them at the time.

Hi,

What I would suggest is to try yo emerge @world first with a reduced
list of USE flags, maybe the default, and after success you could
introduce back the wanted USE flags and emerge @world once more.

It could be a bit too much compilation, but if you have already binary packages, it will not be so expensive the second round, IMHO.

Best

Can you paste the few lines showing the first circle? Add -v to the emerge command to show the USE flags in conflict.

I built a new system a few days ago, and I had to break out of a couple of cycles, separately of course. I don't remember just what they were at the moment, but seeing yours should help.

Now you mention it, that's what I did last time, although my loop emerge
ten lines at a time to cut down on the number of dependency
recalculations.

I seem to remember a harfbuzz loop that was a nightmare to fix ...

Can't remember what it collided with, but if you can manage to emerge
that and the other one, that might cure the loop ...

Good day!

First of all, sorry for the late reply. I had to attend to a course a
bit far away from home and it was pretty intense.

Now, back home, I'll try the suggestions, thanks!

Just for the sake of preventing a future failure, besides personal
files (minimum and obvious) the "world" file and the binary packages,
built along with the package installation, what else should I backup
so that I would be able to quickly restore the same full working
Gentoo in a new hardware without having to work from stage3 up? The
portage tree is one of those items, for sure. But what else?

Thank you all and a good sunday.
Francisco
