I tested and the errors coming from bitcoind cleared up on darwin.

But for some reason, the resulting lightningd binary does not have a --bitcoin-datadir CLI option on a darwin build:

lightningd: --bitcoin-datadir=/tmp/cashu-rs-mint/bitcoin: unknown option

This does not happen on linux.

edit: this seems to be an issue with the clightning derivation on darwin.
reported here NixOS/nixpkgs#305060

Thanks for this. I am not currently testing on darwin but I should. I'm happy to merge the changes as they're working for me on nixos but haven't run them on darwin. Looking at @plebhash's comment it looks like it fixes one issue but creates another so still doesn't work on darwin?

Yes it is an issue reported upstream to NixOS/nixpkgs. We should wait for updates there.

This is ready to merge now, ping @thesimplekid.

was there any progress on the clightning derivation for darwin?
I don't see any updates from the issues I created.

• lightnind is missing CLI options on darwin ElementsProject/lightning#7241

Ok I saw wrong issues, thanks for linking the right ones :)
