Python 3.10 support?

[dmartin]

Hi, would it be possible to add wheels or build support for Python 3.10? I ran into this problem when trying to build from source:

I am running into the same issue when installing on Python 3.10
Could someone pick up this issue and work on a fix?

py310 wheels would fix this: #35

If performance is not an issue, you can use pymmh3.
https://github.com/wc-duck/pymmh3
pip install pymmh3

It doesn't require compiling any of C++ code and is fully compatible with Python 3.10.
Drawback is that performance is worse (it matters only for bigger data blocks) and it doesn't support "signed" argument (it's always signed).

You can use them both at the same time.
Example:

try:
	import mmh3
except ImportError:
	import pymmh3 as mmh3

print(int.to_bytes(mmh3.hash("string test"), 4, byteorder="little", signed=True))

Excuse me for the delay. Version 3.1.0, which provides Python 3.10 and 3.11 wheels, is now released. Please try the new version.
