The contents of the compilation error and how to resolve it.

The compilation is not working.I used a different computer, but when I set the same settings, the compilation stopped working.I read the error, but I didn't understand it well, so I asked a question.
Environment

OS:ubuntu 18.04
IDE:Vscode
The same is true of the environment that we are verifying.

I'm a beginner at expressense, so I don't think I understand anything, but I'd appreciate it if you could give me guidance.

Based on the content of the link error, I suspect that you are building a low-double ELF application using the system() function without the System Command enabled.

Enable the following System Command (CONFIG_SYSTEM_SYSTEM) in the menuconfig before building.

->Application Configuration
 ->System Libraries and NSH Add-Ons
  [*] System Command

I'm sorry if I missed your expectations.
