I was able to build it here.
Can you show me a slightly earlier log of this log?

buildlog.txt
This is a complete log

@Raivon

Run this command and let me know the result

You probably don't have multilib installed in your host environment.
Run this command to install multilib.

sudo apt-get install gcc-multilib g++-multilib

sudo apt-get install gcc-multilib g++-multilib

I have installed libraries beforehand
g++-multilib is already the newest version (4:8.3.0-1). gcc-multilib is already the newest version (4:8.3.0-1).

Maybe the problem is in the Windows WSL ? But other modules build without errors.

[Raivon]

I confirm. The problem is in the Windows WSL subsystem.
After upgrade Windows 10 to build 2004 or later you must upgrade installed WSL images to WSL2 or reinstall it.
Thank you!
