Re: compilation error on Apple M1

[Aleix Conchillo Flaqué]

Hi Damien,

This looks like a linking issue probably related to how things are installed in your system, not with Guile itself. And the issue seems to be with libiconv. Usually that comes with macOS itself and is located in /usr/lib/libiconv.2.dylib.

Building Guile on M1 is definitely possible and works. I would suggest using Homebrew which already has all Guile dependencies figured out. Actually, I just recently added the Apple Silicon chip fix that Colin mentions to Homebrew as well (https://github.com/Homebrew/homebrew-core/pull/118698), because even if you solve the issue you are currently getting you are going to run into the next one (which is that you need to disable JIT which makes Guile very slow unless you apply that fix).

Also, if you use Guile from Homebrew you will benefit from Guile Homebrew which has all these packages ready to be used: https://github.com/aconchillo/homebrew-guile/tree/master/Formula

Some people dislike Homebrew very much and refuse to install it, so I totally understand if that's the case.

Best,

Aleix
