[yocto] Non-deterministic build error in package gcc-source

Tue Aug 7 01:30:17 PDT 2018

We got about 60 stable builds with the archiver configured in source "original" and diff "1" mode as described in my last mail. So for us, this seems to solve the problem.

Anyhow I would still like to report the bug. Are there any other ways than using Bugzilla?

Kind regards,

Erik

Hi Ross,

thanks for your response!

I deactivated the archiver and started about 40 builds. The problem did not occur.

We discussed the different archiver modes. For us, it is probably the best solution to run the archiver with the following configuration:

ARCHIVER_MODE[src] ?= "original"

ARCHIVER_MODE[diff] ?= "1"

To get the original source files and the patches.

I am running some builds right now to evaluate if this configuration runs without problems.

In any case I would like to report a bug concerning the problems when running the archiver in patched mode. I tried to create a Bugzilla account, but it was not possible, because all of my tries were automatically cancelled. I wrote an email to michael at yoctoproject.org and hope to get an account soon.

Kind regards,

Erik

Obvious short answer is do you actually need to use the archiver in
patched mode?  Changing to a different mode, or disabling the archiver
entirely, may solve this.

Long answer is this is most likely a race in the archiver, so filing a
bug with as many details as you can would be good.
