Any chance you are on an older version of the hc tool. The latest pulls templates from our repos (or any repo actually) and these definitely have the correct version of hdk_proc_macros with underscores.

I'm switching to working on my desktop.

I can check on the laptop, but as I don't plan to use it, unless others report the same issue, it seems redundant now.

Running nix-shell https://holochain.love (or nh via an alias) I got a build error.

copying path '/nix/store/mwazh1aylx9c4dfrd73a1m4y7rrbv6xr-zlib-0.6.2.1' from 'https://cache.nixos.org'...
error: cloning builder process: Operation not permitted
error: unable to start build process

On my desktop I still had nix-env (Nix) 2.2.2, so I upgraded.

I also had this line in my ~/.zshrc which I commented out:

# export NIX_PATH="nixpkgs=https://github.com/NixOS/nixpkgs/archive/release-19.03.tar.gz"

Running nh again gave:

cannot build derivation '/nix/store/7x70dgh5yj743lcdyahl9ywmf1518rqd-rust-1.38.0-nightly-2019-07-13-69656fa4c.drv': 1 dependencies couldn't be built

I tried this again on the desktop:

Closing as hc package now works on my laptop, although I get an error with hc run. #1926
