Steps to reproduce the behavior

python3.8 -m pip install cchardet OR pip3 install cchardet

The same on:

• Python 3.10.1
• Lubuntu 20.04

UPDATE:

SOLVED

In my case, I solved the error by running:

apt-get install python3.10-dev

This is a different error than I ran into but since it failed initially on the same source code file, you may need to check some requirements. My error was due to cc1plus missing. I needed to install g++ since although gcc is installed by default, g++ is not (at least on ubuntu 20.04 for aarch64). This fixed my problem and cchardet now installs correctly. The source of your error may be similar.

Can confirm, you need to have gcc and g++ to install, as well as python3.X-dev
