Re: Request:How to install gcc in ubuntu18.04 int the way of offline?

What is MCU? Microcontroller unit? What's the relationship to apt-get?

The problem is just as the error message says. You can't build gcc without
an existing C compiler. Perhaps your real problem is getting "apt-get
install" to work, and not building gcc from scratch without an existing
compiler.
