Newsboat requires Rosetta (Intel emulation) on aarch64-darwin

heywoodlh commented 6 months ago

Describe the bug

In order to install the newsboat package from nixpkgs on Darwin, Rosetta must be enabled. If not, a build failure occurs (in this snippet I was trying older branches of nixpkgs -- but the same issue happens with nixpkgs-unstable):

❯ nix shell github:nixos/nixpkgs/release-23.05#newsboat
error: builder for '/nix/store/7kcayxwk8khycxw1agmcyfm9vpsqpw4s-bootstrap-tools.drv' failed with exit code 71;
       last 1 log lines:
       > sandbox-exec: execvp() of '/nix/store/0ihnd9fxych0030mxhg50pz0fivzpmmq-sh' failed: Bad CPU type in executable

...

Steps To Reproduce

Steps to reproduce the behavior:

Attempt to install newsboat from nixpkgs on M1 Mac without Rosetta enabled
Observe failure

Expected behavior

The aarch64-darwin app should be able to be built without Rosetta. Or Rosetta should be turned on as part of the installation perhaps.

Additional context

I'll try to see if I can figure out how to fix the build (after I figure out how to uninstall Rosetta :smile:) and submit a PR

nix shell github:nixos/nixpkgs/release-23.05#newsboat

I doubt that would fix it but note that 23.05 is not supported anymore.

Yes, see my comment here:

I found some other issues talking about this. As you've found out, it seems like the sh binary used in the darwin stdenv on aarch64 is wrong. see this file here: https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/darwin/bootstrap-files/aarch64-apple-darwin.nix

my local test:
