Formula 'chicken' (scheme) doesn't link properly on Apple M1

[jcguy]

Steps to reproduce: brew install chicken && csi -ne '(import (chicken tcp))'
Expected output: successful install followed by nothing (a successful import)
Actual output: successful install followed by: this error

I am able to fix this problem by symlinking /opt/homebrew/lib/libchicken.dylib (which is itself a symlink to /opt/homebrew/Cellar/chicken/5.3.0/lib/libchicken.dylib) to /usr/local/lib/libchicken.dylib. I was also able to fix this problem by setting the following envvar:

>> DYLD_LIBRARY_PATH=/opt/homebrew/lib/ csi -ne '(import (chicken tcp))'

However, I am not familiar enough with the Homebrew formula or the Chicken build system to figure out how to fix this in a better way. Has anyone else experienced this issue?

You need to ensure /opt/homebrew/lib is in your include path. On Intel Homebrew installs in a path that's in the include path by default but on ARM that's up to the user.

[jcguy]

Is this documented anywhere? Would it be possible for Homebrew to set up the include path on install?

[SMillerDev]

https://developer.apple.com/library/archive/documentation/DeveloperTools/Conceptual/DynamicLibraries/100-Articles/DynamicLibraryUsageGuidelines.html documents how to use dynamic libraries. And I'm sure whatever tool you're using has documentation for it too.

Since there's no one way to set up libraries Homebrew can't do this for you.

I've opened Homebrew/homebrew-core#101481 to fix this.

Should be fixed now. Just do brew update && brew upgrade chicken.

Thank you! I thought it might have to do with rpath, but wasn't able to figure it out myself.
