Running embedded claude executable fails on NixOS

[IwailerI]

Issue specific to NixOS. Verified with both user systemd service and a manually started system package.
Using latest (v1.42.1 currently)

All queries result in the following error:

e11d56c8-022f-4f84-a169-54deab771463 sdk_termination reason=process_exit exit=127 model=sonnet resume=false deferred=false stderr="Could not start dynamically linked executable: /nix/store/pxvw9hzrbh6x309nbxz0j37d39az4n1s-meridian-1.42.1/lib/meridian/node_modules/@anthropic-ai/claude-code/bin/claude.exe\nNixOS cannot run dynamically linked executables intended for generic\nlinux environments out of the box. For more information, see:\nhttps://nix.dev/permalink/stub-ld"

Unescaped stderr:

Any help greatly appreciated.

This is a NixOS issue, not a Meridian/Claude bug.

The bundled claude.exe is actually a Linux binary, but it’s dynamically linked and expects a normal Linux filesystem + dynamic loader setup. On NixOS this isn’t available by default, which is why you get the stub-ld error.

Fix is to enable nix-ld:

sudo nano /etc/nixos/configuration.nix

Add:

programs.nix-ld.enable = true;

Then apply:

sudo nixos-rebuild switch

Restart Meridian after that — it should run fine.
