Compatibility with arm on MacOS

[rigille]

Currently the official version of ChezScheme doesn't support MacOS with arm architecture, but Racket's fork does. Unfortunately Racket's fork isn't compatible with chez-exe. For instance my bootpath has no kernel.o

/usr/local/lib/csv9.5.5.4/tarm64osx$ ls
libkernel.a  libz.a   petite.boot  scheme-script.boot scheme.h
liblz4.a  main.o   revision  scheme.boot

I would like to solve those incompatibilities, but I currently don't know how to go about it. Any ideas?

Hey, this is a bit of a weird one. It looks like the racket folks have decided to change the build process and no longer bundle the 3rd party static libraries needed by chez scheme into kernel.o, and instead produce libkernel.a, which is only the stuff compiled from the chez scheme c source files. I can play with the build process, but I don't have an arm mac, so I can't test that specifically. I can build the racket/cs fork on my computer and test against that, which might get it working for you.

That would be great, I think just testing with the fork is likely to work. If I can help somehow let me know 🙂

./configure has an option --kernelobj which builds kernel.o instead of libkernel.a. You can then link with the libraries that are not included: g++ -I /usr/local/lib/csv9.5.5.5/tarm64osx /usr/local/lib/csv9.5.5.5/tarm64osx/kernel.o -liconv -lcurses main.cpp.

Something I haven't figured out is that (display) seems to be having some weird behavior.

Using --kernelobj is working for me :D What kind of weird behavior did you observe from (display)?

Great! Glad it was helpful :)

I think it's just a result of embedding chez scheme, but I was having issues with (display) not working until it was called a few times.
