Compiler check fails while configuring cereal

[ianacaburian]

Looked into previous (closed) issues and tried running nix-shell --pure as you suggested to others.

Unfortunately, being on macos, there are now errors with trying to create a build dir within the zug repo that already contains a BUILD file.

Running nix-shell --pure --show-trace produces the following log:

these 7 derivations will be built:

The dependencies in this repo haven't been updated in quite some time. Probably this can be fixed by upgrading nixpkgs, lager, immer and zug. This may also require slightly adapting the code as there are small API changes in Lager since it was last updated I reckon.
