Hi there, I tried to follow the example in README and got following error:

ImportError: dlopen(/Users/xxx/for-rustimport/playground/lib.cpython-39-darwin.so, 0x0002): tried: '/Users/xxx/for-rustimport/playground/lib.cpython-39-darwin.so' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')), '/System/Volumes/Preboot/Cryptexes/OS/Users/xxx/for-rustimport/playground/lib.cpython-39-darwin.so' (no such file), '/Users/xxx/for-rustimport/playground/lib.cpython-39-darwin.so' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64'))

Does rustimport support m1 pro chip? Thanks.

My env:
Macbook Pro 14, macOS 13.4.1
python 3.11
venv

Hm, this should work and afaik people have successfully used rustimport on M1 already.

Sadly, I know little about macOS and also don't own a mac so I can't reproduce this myself. However, from searching around I see that this might have to do with your llvm installation. Could you try following these steps - https://stackoverflow.com/a/71925201?

And if that doesn't help, could you try setting these environment variables before running your script?

export ARCHFLAGS="-arch x86_64 -arch arm64"
export PYO3_CROSS_LIB_DIR=/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.11/lib
export RUSTIMPORT_FORCE_REBUILD=true

With ARCHFLAGS and RUSTIMPORT_FORCE_REBUILD, it works.

Thanks for the reply.
