fail to build ns3 on Windows 10 WSL Ubuntu20.04 refusing to run as root

[tonyLau]

I am trying to configure the ns3 as the guide told, even if I add --enable-sudo, error still occurs. What have I do wrong? Do I need to switch user (it's hard to do so on WSL)? If no, is there any other ways besides installing Ubuntu on VM box?

The not-run-as-root is a failsafe measure, I guess it's more important for Linux and Mac users than for Windows, but I'm not a Windows expert.

In any case, the answer is... yes, you need to run it as normal user (not root). As far as I know, it shouldn't be hard to change the default user.

Do not use sudo su. 

When you setup WSL, you need to specify an user name and password. 

You should use them.

If you are using docker inside wsl, you shouldn't be seeing this.
