Universal wheel for macOS contains only x86_64 build

[doronz88]

When installing the package on an Apple Silicon, the universal wheel being installed is only for intel.

This can be examined:

file /opt/homebrew/lib/python3.11/site-packages/capstone/lib/libcapstone.dylib
# outputs: /opt/homebrew/lib/python3.11/site-packages/capstone/lib/libcapstone.dylib: Mach-O 64-bit dynamically linked shared library x86_64

As a result, capstone will fail to import on Apple Silicon.

Do you want to use Capstone for AArch64 binaries? If yes, I highly recommend to use the auto-sync branch and cherry-pick the commits from this PR to make it build on ARM Macs.
Regarding the wheel: cc @kabeor Any progress with this?

[doronz88]

I want it to not crash. Not even disassembling.

About MCInstPrinter.c, I guess default is missing from switch-case at line 88.

Since the code comes from #1949, Would you mind to have a look? @Rot127

[kabeor]

Should be fixed in #2160.

However, the homebrew way is not maintaining by us, compiling source code is ok.

[doronz88]

@kabeor I'll wait for the published .whl package to report when this issue is resolved

[orid95]

I'm also encountering the same problem. Is there a release schedule coming soon so I can install the package directly from pypi instead of building it myself?

[guyshe-jfrog]

A possible workaround could be to force it to build the x86_64 dylib, then link them together using lipo. But I can't seem to get the x86_64 dylib built. Even if I run

arch -x86_64 python setup.py bdist_wheel

The resulting dylib is arm64. Same result for the cython build.
This might also be a hint to what is going wrong, something is detecting the arch in a different way.
