I'm running in nix develop, and some example apps (notably interactive/ ones) recently started me error messages about OpenSSL. Is it required to be installed on my system? Do I need to do anything manual? Was there some change to Roc or Nix recently regarding SSL?

I can create an issue if this is complex. Here's the error message:

  Could not find directory of OpenSSL installation, and this `-sys` crate cannot
  proceed without this knowledge. If OpenSSL is installed and this crate had
  trouble finding it,  you can set the `OPENSSL_DIR` environment variable for the
  compilation process.

  Make sure you also have the development packages of openssl installed.
  For example, `libssl-dev` on Ubuntu or `openssl-devel` on Fedora.

  If you're in a situation where you think the directory *should* be found
  automatically, please open a bug at https://github.com/sfackler/rust-openssl
  and include information about your system as well as this message.

Should be possible to add it in nix I would expect. Probably got added as a dependency on a machine that already had it install. Actually a bit surprised you don't have it installed given how common it is.

Relevant issue created! https://github.com/rtfeldman/roc/issues/3632

We really need to create some tests for those interactive examples :p I'll make an issue for that.

Thank you!

do we know which dependency pulls in openssl?

view this post on Zulip Richard Feldman (Jul 25 2022 at 16:56):

I assume reqwest - we just switched to that recently

view this post on Zulip Richard Feldman (Jul 25 2022 at 16:56):

oh, it has a feature that lets you use rustls instead of openssl

view this post on Zulip Folkert de Vries (Jul 25 2022 at 16:57):

right that was going to be my suggestion

view this post on Zulip Richard Feldman (Jul 25 2022 at 16:57):

yeah I'll make a PR

@JanCVanB can you try the rustls branch and see if CLI examples work for you?
