Compilation error on Mac M1

[thbar]

I'm going to start using evision a bit for different experiments. Today I cloned the repo and ran mix test, but I'm facing an error. Reporting it here in case it helps other, but I will likely look into it.

EDIT: my OS is MacOS 13.2.1 (22D68) (Ventura).

$ mix test

Trying with export EVISION_PREFER_PRECOMPILED=false as mentioned in the README, currently compiling...

[thbar]

Tests passed this way. I'll keep the issue opened.

Hi @thbar, this is the intended behaviour, i.e., users should install evision from hex.pm instead of compiling it from Git source. And as documented in the README.md, set EVISION_PREFER_PRECOMPILED env var to false should do it, as what you've found above.

EVISION_FETCH_PRECOMPILED=true mix evision.fetch --all is used for developers to fetch all precompiled binaries on GitHub, compute their sha256sums and publish a new version on hex.pm. It's not the intended command for users to use.

Hi @cocoa-xu! I was happy to pull from git in order to have a closer look at how it works. Thanks for the clarifications!
