[Holochain developer tools installation] Build fails on MacOS Big Sur

[jost-s]

When running nix-shell in the folder developer-exercises, the build fails with an error when compiling holochain itself.

That error is recorded here in the holonix repo https://github.com/holochain/holonix/issues/211. It's resolved in the current build, so nix-shell https://nightly.holochain.love as described in the official docs works fine.

I suppose it's a matter of updating default.nix or mentioning in "Requirements -> Setup" that for MacOS 11 another version is needed.

Okey so that is interesting... In theory we are in the latest holonix version. Are you trying to enter the nix-shell with the latest version of the repo?

Any ideas @steveej?

Yes, I have pulled most recent sources. The latest commit is from 29th of June.

The exact error I'm getting is

Sorry, I realize now that this is duplicate and in the wrong repo.
