Re: [yocto] Reproducible builds not working with musl?
You have to find them yourself with gut bisect I would say. Too many things have changed. Alex On Mon 21. Nov 2022 at 17.07, Kenth Eriksson wrote: > I see.

I see. Any particular fixes you can point me to that may be relevant also for musl? -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Testing reproducibility properly is a heavy exercise (you need to build everything from scratch, then compare), and so we do it only for glibc. There have been recent fixes and tests to check that host paths do not leak into target files, but dunfell probably has neither the fix nor the test. This is correct; it's hard for upstream to test every possible combination for reproducibility. We do try to get some decent coverage, but ultimately if you really care about reproducible builds, you should setup a reproducible build test for your exact combination. We've tried to make this pretty easy, see https://youtu.be/zXEdqGS62Wc?t=1021 Alex -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
