No, it's not. The issue seems to be that add-apt-repository adds 
a source for the current Ubuntu version which is groovy which 
doesn't provide a Release file. Some such. It works when I take 
the ppa from Ubuntu bionic.

Anyways, I managed to install gcc-9 and g++-9 from the ubuntu 
toolchain ppa in the Docker container [1] and it builds 
successfully.
I instructed Cirrus CI to clone the repository like so
> git clone --branch=master-ci --depth=1 
> https://github.com/W-joe/gcc /tmp/cirrus-ci-build
and it reaches the configure stage in the buildci [2] script, 
however it fails.

It says that it's not using the GNU C++ compiler, why is that ?
Also, shouldn't g++-9 support C++11 ?

I suspect that maybe the compiler wasn't properly installed in 
the container ?

This is the log:
