Error installing on Apple Silicon

[Default] OSError: dlopen(/Users/andrewl/Library/Application Support/Binary Ninja/python311/site-packages/capstone/lib/libcapstone.dylib, 0x0006): tried: '/Users/andrewl/Library/Application Support/Binary Ninja/python311/site-packages/capstone/lib/libcapstone.dylib' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64')), '/System/Volumes/Preboot/Cryptexes/OS/Users/andrewl/Library/Application Support/Binary Ninja/python311/site-packages/capstone/lib/libcapstone.dylib' (no such file), '/Users/andrewl/Library/Application Support/Binary Ninja/python311/site-packages/capstone/lib/libcapstone.dylib' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64'))

The wheel or whatever ends up with a dylib only for x86_64 instead of arm64.

When you delete plugins, the dependencies aren't deleted. So you can verify by removing keypatch, navigating to ~/Library/Application Support/Binary Ninja/python311/site-packages, deleting capstone and capstone-5.0.1.dist-info, then command palette for "Install python3 module...", enter capstone. The directories will reappear and:

$ file ./capstone/lib/libcapstone.dylib
./capstone/lib/libcapstone.dylib: Mach-O 64-bit dynamically linked shared library x86_64

Another test is to look how Binja actually installs stuff, how it invokes PIP:

[Default] Running pip ['/opt/homebrew/Cellar/python@3.11/3.11.6_1/Frameworks/Python.framework/Versions/3.11/bin/python3.11', '-m', 'pip', '--isolated', '--disable-pip-version-check', 'install', '--upgrade', '--upgrade-strategy', 'only-if-needed', '--target', '/Users/andrewl/Library/Application Support/Binary Ninja/python311/site-packages', 'capstone']

We can then replicate this call outside of Binja and verify:

$ pip --isolated --disable-pip-version-check install --upgrade --upgrade-strategy only-if-needed --target /tmp/test capstone
$ file /tmp/test/capstone/lib/libcapstone.dylib
/tmp/test/capstone/lib/libcapstone.dylib: Mach-O 64-bit dynamically linked shared library x86_64

Capstone seems aware of this issue: Universal wheel for macOS contains only x86_64 build #2154.

Workaround: Install capstone with brew and then copy its arm64 .dylib into your pip installation.

$ brew install capstone
$ file /opt/homebrew/Cellar/capstone/5.0.1/lib/libcapstone.5.dylib
/opt/homebrew/Cellar/capstone/5.0.1/lib/libcapstone.5.dylib: Mach-O 64-bit dynamically linked shared library arm64

Use brew ls -v capstone if you're having difficulty seeing where it installed the dylib.

$ cd ~/Library/Application\ Support/Binary\ Ninja/python311/site-packages
$ cp /opt/homebrew/Cellar/capstone/5.0.1/lib/libcapstone.5.dylib ./capstone/lib/libcapstone.dylib

And restart Binja and log should show:

...
[Core] Loaded native plugin debuggercore
[Plugin Repository: community] Loaded python3 plugin 'lwerdna_keypatch_binja'
[Core] Loaded native plugin pythonplugin
...

Another way to get the correct arm64 dylib is with:

$ pip install --target /tmp/test "git+https://github.com/capstone-engine/capstone#subdirectory=bindings/python/"
