[priv-kweihmann]

Package version (if known): 3.0.1

Describe the bug

Compilation on x86-64 (and potentially all other platforms) fails

Steps to Reproduce

Try to compile the c extension with python 3.11.0 release, up to py 3.10.6 everything at least compiled

Expected behavior

c extension compiles

Screenshots (if applicable)

Likely an issue with the code generation from cython - there are several issues in the cython upstream bug tracker that claim to have fixed this - so I guess a refresh of the c code should do it using the latest cython master

[pombredanne]

@priv-kweihmann Thanks, the likely solution is to regen the C code indeed!

[pombredanne]

Keeping this open until we have a stable fix upstream
Likely with cython/cython#4827 or cython/cython#4681

I hit a similar compilation error for this library with Python 3.10 installed (while trying to install scancode, @pombredanne). I am doing so on an Mac M1 arm chip:

I released macOS fat binary "universal" wheels in the last few days. These are not for Linux ARM though they should work on macOS M1 natively.

Could you test if these pre-built binaries work on your machine with a pip install?
