Link error on ubuntu

I notice below error when attempting compilation from the master branch. I am not sure if the master branch is broken (unlikely) or if I missed to install any build dependency

 make V=1
I ccache not found. Consider installing it for faster compilation.

you gcc version 9.4.0 maybe too old, please upgrade it
