Usually, you will need to provide a bit more information about your system (OS, version, ...) in order to get help.

[2shaar2059]

Sure, does this help?

OS: Ubuntu 20.04.4 LTS x86_64 Kernel: 5.4.0-113-generic CPU: Intel i7-6500U (4) @ 3.100GHz GPU: NVIDIA GeForce GTX 950M GPU: Intel Skylake GT2 [HD Graphics 520]

python3 --version: Python 3.10.4

gcc --version: gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0

[christian-rauch]

Thanks. I am using the same system without issues. But my python version is:

$ python3 --version
Python 3.8.10

According to https://packages.ubuntu.com/focal/python3, the newest python3 package should be version 3.8.2-0ubuntu2.

Are you using python3 from another source? My bet is that you have different versions of runtimes (python3) and development packages (python3-dev) installed. Both versions should match.

Did you try with the standard packages (version 3.8.2-0ubuntu2) in Ubuntu?

Edit: If you do a reverse search for file libpython3.10d.a it will tell you that this file does not belong to a package in focal, but only in the newer jammy.

[2shaar2059]

I see, thanks.

[christian-rauch]

Did reverting back to version 3.8.2 solve your issue?
