We are having problems using NixOps from Mac OS X due to the different arch:
x86_64-darwin (vs.) x86_64-linux
We have a built-host setup according to this manual(s):
Nix installation
https://nixos.org/nix/download.htmlbuild-host setup (VirtualBox guest)
https://functional-orbitz.blogspot.de/2013/05/setting-up-nixops-on-mac-os-x-with.html(see step 5. Setup Distributed Builds)
ssh nix-build-serverworks and we set these environment variables on the mac:
NIX_BUILD_HOOK NIX_CURRENT_LOAD NIX_REMOTE_SYSTEMSwith the values from the manual.
Question. On Linux i would use: strace -f -e execve nixops ... to see what programs are called or at least to see what arguments they are called with. How to find out what command returned the unexpected end-of-file error?
Error. We see that nixops wants to use the buildhost and outputs:
nixops deploy -d test -I nixpkgs=/Users/josh/.nix-defexpr/channels/nixos/ --show-trace
building all machine configurations...
using predefined remote systems file: /Users/josh/sample_clj/remote-systems.conf
these derivations will be built:
