Build fails on macOS using nix

[nhooyr]

• nvim --version: using latest master
• Operating system/version: macOS 10.12.2
• Terminal name/version: iTerm 3.0.13
• $TERM: xterm-256color
• nix version: nix-env (Nix) 1.11.5
• nixkpgs version: "17.03pre-git"

Actual behaviour

I cloned the repository and then:

❯ make CMAKE_BUILD_TYPE=debug                                                                                                                                                                              i

make: *** [build/.ran-cmake] Error 1

I am using nix on darwin (i have a feeling this is relevant).

Expected behaviour

No error, successful build.

Have you built successfully in this environment before? Is there anything in CMakeOutput.log or CMakeError.log that looks relevant? If you make distclean && make CMAKE_BUILD_TYPE=Debug (note the captial D), does it work?

[nhooyr]

No, I have not, that's why I felt mentioning nix is relevant.

CMakeOutput.log: https://gist.github.com/73bdf8fc03f79e525d302e991bfe62a4
CMakeError.log: https://gist.github.com/6b4c9b7de1147e25c4ffc5299517b45f

Nope, same error as before. I can post the full output if that would help.

[nhooyr]

Yup, installed brew and now it all works fine. Weird.

[nhooyr]

According to the Nix IRC, this is expected and there isn't much that can be done. According to them, I should be using Nix to build neovim and specify all dependencies explicitly.

[nhooyr]

It's a simple fix. For anyone in the future!

Run

cd path/to/neovim
nix-shell '<nixpkgs>' -A neovim
patchPhase
cmakeConfigurePhase
buildPhase
installPhase

And then enjoy :)

@nhooyr I'm trying to replace Homebrew with Nix and what confuses me is that to execute Neovim after it is build I need to switch the Nix environment with nix-shell. Is there a way to avoid that?

[guyzmo]

@tssm you'll need to learn about nix' profiles so you can deploy neovim either in your current profile, or a given profile you'll switch to.

Thanks @guyzmo!
