Fails to install on Python 3.11 because cchardet can't build

[aquatix]

On installing warcit in a python 3.11 venv, I get a compilation error:

      creating build/temp.linux-x86_64-cpython-311/src/ext/uchardet/src/LangModels
      x86_64-linux-gnu-gcc -Wsign-compare -DNDEBUG -g -fwrapv -O2 -Wall -g -fstack-protector-strong -Wformat -Werror=format-security -g -fwrapv -O2 -fPIC -Isrc/ext/uchardet/src -I/home/mbscholt/.virtualenvs/divault-pyramid/include -I/usr/include/python3.11 -c src/cchardet/_cchardet.cpp -o build/temp.linux-x86_64-cpython-311/src/cchardet/_cchardet.o

This is a known issue with cChardet: https://github.com/PyYoshi/cChardet/issues/81 and has not been fixed since last year. It's unlikely that it will be fixed soon.

There are options to for example move to a fork at https://github.com/faust-streaming/cChardet but also updating to a recent Cython helps (tested): pip install --upgrade Cython. Maybe add the latter as a dependency for Python 3.11 and up?

The same issue occurs with Python 3.10.x. However, on Python 3.9 you can simply run python setup.py install to set everything up just fine.

You can use a venv/conda to set up a 3.9 environment easily.

Python 3.9 is not an option for us, as warcit has to work inside a bigger project that targets Python 3.10+
