   Command not found

I think I have an idea what the problem might be. You're running NixOS, right? The fake toolchain assumes the existence of /bin/bash and /bin/true, neither of which exist for you. (It appears you do have /bin/sh symlinked to bash, but I can't make that assumption without breaking things for Debian, etc.)

So there's basically two things that need to be done:

  • modify the scripts to be dash-compatible so they can use /bin/sh
  • replace the link to /bin/true with a shell script. That'll probably result in a slight performance hit, but I guess it can't be helped

Can you checkout the nixos_support branch and see if it works now?

You're running NixOS, right?

That's right. Sorry I don't mean to cause you trouble since I'm running a non-standard distro. Hopefully there is a way to do things so that it works in a standard way for all distros and other POSIX-compliant systems.

This change got me past the previous error. Now I'm getting something different - cmake is not finding any dependencies. For comparison, I also include what it looks like when I run cmake normally without YCM-Generator.

Sorry about the delay in replying - I'm in the middle of my exams atm so free time is scarce.

Sorry I don't mean to cause you trouble since I'm running a non-standard distro. Hopefully there is a way to do things so that it works in a standard way for all distros and other POSIX-compliant systems.

It's cool, all the changes so far have made the code more portable rather than just adding special cases, so I don't mind.

Can you see if using -e enables it to find the dependencies? And if not, can you post the value of $PATH in your shell?

Nice, that worked. Apologies for not noticing and trying the -e option. Hmm but it seems like that might be a good thing to preserve the environment variables by default, no?

By the way, in case you're curious, here's the config I ended up using:

https://github.com/andrewrk/genesis/blob/5f49cd9a8c2b61b9859a22102bc3f732add9461a/.ycm_extra_conf.py

It's not the output of YCM-Generator, although the YCM-Generator template was a good starting point that I used. I ended up going with a hybrid of using cmake's generated compile_commands.json and for some reason on NixOS I needed to give YCM the path to stdlib.h and friends. So I did that by executing echo | cc -xc -E -v - and echo | cc -xc++ -E -v - where cc is the C compiler in the CC env variable, and parsing the output of those commands to find out where the include paths are.

IIRC, the reason -e isn't the default was to improve reproducibility and simplify debugging. If a set environment variable changes the behaviour, it makes debugging this kind of error much harder, compared to telling everyone to just try using -e.

BTW, you might want to figure out which variable is the relevant one, since that'll probably cause problems for you at some stage due to Nix being so different.
