Sadly a known issue Homebrew producing non-standalone static libraries. One can really ask oneself what the point is of static libraries when the libraries retain dependencies on dynamic libraries.

[lerno]

For now, using Homebrew to get c3c, grab LLVM from homebrew just to get the dependencies or building it yourself are the available solutions. I am very sorry about this.

[lerno]

What we need is a CI similar to https://github.com/c3lang/win-llvm but for MacOS which creates builds for Aarch64 and x64. Then we could use those to build C3 instead.

yeah im experiencing this on M3 too.. missing a lot dylib

I has this problem too.

The temporary fix is make a symlink '/opt/homebrew/opt/llvm@17/lib/libunwind.1.dylib' refer to the original 'libunwind.1.dylib' in unwind folder (I have libunwind.1.dylib but inside unwind folder in lib)

Why not bundle a version of libunwind? It's not a huge library...

[lerno]

This is what building a custom version of LLVM could do.

Temp Fix

c3c it's looking for libunwind from LLVM 17 and some Homebrew stuff.

➜  otool -L c3c | grep libunwind
	/opt/homebrew/opt/llvm@17/lib/libunwind.1.dylib (compatibility version 1.0.0, current version 1.0.0)

a quick fix is run:

brew install llvm@17

I got the compiler working on LLVM 19.1.6 by just grab the codebase and build it on my machine. Building from source prevents a lot of annoying dylib problems. (I did encountered some problem while building though, that's because now llvm and lld become two different packages in homebrew so I adjusted some settings to make it find the lld libraries)

brew install llvm@17 also just worked for me.

This is in progress but will probably not be fixed quite yet.

I had newer versions of llvm and lld installed (Looks like they were split since 19) but was able to clone and build c3c from source with cmake -DCMAKE_PREFIX_PATH="$(brew --prefix llvm)" -DC3_LLD_DIR="$(brew --prefix lld)/lib" ..

Only -DC3_LLD_DIR="$(brew --prefix lld)/lib" is enough if llvm is properly installed by homebrew
