Build fails with certain gcc versions (such as gcc-11):

I can't reproduce with GCC 11.1
I just updated the offending file with BLAKE2's latest version. Can you please check if it's fixed?

madMAx43v3r · 2021-06-10T12:04:10Z

unfortunately https://github.com/Chia-Network/bls-signatures.git is not compatible with relic master..

dfaranha · 2021-06-10T12:05:44Z

I sent a PR fixing that already, waiting to be merged: Chia-Network/bls-signatures#207

dfaranha · 2021-06-10T20:43:00Z

That was merged, so now we can try again. :)

hoffmang9 · 2021-06-10T20:45:14Z

Things that got delayed by launch and financing and pooling FTW...

dfaranha · 2021-06-10T20:50:15Z

Not a big deal, thanks for merging!

I haven't seen the issue being reported since the fix & merge. If you cannot reproduce it either, then let's consider it fixed.
