Failed to install on macOS 12.4 with M1 chip

[sorae42]

Same issue with #13 but the error seems to be coming from a module and not clang itself.

Using Python 3.10 and PIP 22.0.4.

× python setup.py egg_info did not run successfully.

Hi @skyventuree

What version of cffi are you using ?? If it's <1.15.0 then try installing this version. I believe it's the first providing wheels for arm64.

[sorae42]

cffi is 1.15.0.

[cheofusi]

What is the output of file /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/_cffi_backend.cpython-310-darwin.so ??

[sorae42]

/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/_cffi_backend.cpython-310-darwin.so: Mach-O 64-bit bundle arm64

[cheofusi]

I find the have 'arm64', need 'x86_64' error on an ARM chip weird, probably because I'm not too familiar with M1 Macs. Are you doing x86 emulation in your shell ?? Say with arch -x86_64 /bin/bash ?? What is the output of uname -m ??

[sorae42]

I tried install just-playback on both native and x86 emulation and it yields the same error.

The result of uname -m vary whether if I have Rosetta 2 enabled or not.

[sorae42]

I found the solution:

What I did is that I tried re-installing cffi on Terminal with Rosetta 2 enabled and now the cffi should be in x86_64 as expected.

Now I just remove the 2 parameters in the build ffi file and it successfully installed.
