PS: Please keep in mind that I know I am not a dev, I just a noob EndeavourOS (ArchLinux) user who just wants to use this shell so clear instructions on how to get logs or more/better error messages would be appreciated. Because of that I might have included something other than the error messages in the code. Sorry for that if I did.

xeoslaenor commented 9 months ago

Hello, I get the same error here and could not try nsh so

xeoslaenor commented 9 months ago

It seems that nix 0.26.4 is the last to have these functions inside I have 0.27.1 version of nix on my system

Probably this change : https://github.com/nix-rust/nix/pull/2091/commits All features are now disabled by default and should be explicitly enabled

SteveLauC commented 6 months ago

Hi @xeoslaenor @amethylghostling, Nix maintainer here, Nix has introduced feature gates in a specific version in the past, so to use these functions, one has to turn on the corresponding feature, e.g., for fork(), the feature is process.

nsh does not handle this, so you have to fork it and enable the feature yourself.
