Mac Desktop version; error with make

[Hermanverschooten]

Environment

• Elixir & Erlang/OTP versions (elixir --version): Elixir 1.34.4, OTP 25
• Operating system: MacOS Monterey 12.4
• How have you started Livebook (mix phx.server, livebook CLI, Docker, etc): App
• Livebook version (use git rev-parse HEAD if running with mix): 0.6.3

Current behavior

Evaluating the livebook found at vix gibhub, I get this error:

I thought I missed libvips (a prerequisite), but it is installed.

Expected behavior

I expected it to install/build :vix

When I use the same Livebook using livebook server, it does not have the same issue.

What do which make and which gcc return for you? How have you installed them? Do you do something special to add them to your path?

[Hermanverschooten]

Air-van-Herman➜  ~  which gcc
/usr/bin/gcc
Air-van-Herman➜  ~  which make
/usr/bin/make

There is a gcc in my brew list, so I probably installed it that way.

[Hermanverschooten]

Air-van-Herman➜  ~  which pkg-config
/opt/homebrew/bin/pkg-config

Will this be the cause? I mean /usr/bin is probably in the PATH by default, but the homebrew path is not, that is set in .zshrc.

[josevalim]

Yeah, that’s it. I guess we will need a new setting for additional paths?

[wojtekmach]

Yup. The app runs in a very limited environment:

# MyApp.app/Contents/MacOS/MyApp
#!/bin/sh
osascript -e "tell app \"System Events\" to display dialog \"$(env)\""

[wojtekmach]

So yeah, we basically need to manipulate $PATH somehow but worth noting that such notebook is not reproducible, in order to run it we need to run in a specific and implicit build environment. So it's a no-no for sharing but obviously it is an important scenario for just exploring things. For that I think it'd be best to manually adjust $PATH by calling System.put_env("PATH", ...) before Mix.install call. Would that work?

We're also hoping to see packages not needing build environment thanks to projects like:

• https://github.com/philss/rustler_precompiled
• https://github.com/cocoa-xu/fennec_precompile

[Hermanverschooten]

That would probable also solve the issue @wojtekmach closed for nmake on windows #1248 .

[Hermanverschooten]

@wojtekmach I added

path = System.get_env("PATH")
System.put_env("PATH", path <> ":/opt/homebrew/bin")

That got me further but now it complains it cannot find "erl_nif.h".

[wojtekmach]

Ok lack of erl_nif is a bug, will look into it.

[wojtekmach]

The missing erl_nif.h fix is out in updated release artifacts, thanks again for the report! https://github.com/livebook-dev/livebook/releases/tag/v0.6.3

[Hermanverschooten]

@wojtekmach Just to confirm that it now does work, thanks!
