Comment (by rmottola):

 forcing gcc7 yields:


 {{{

   flags to enable it.

 so yes, we need a newer c++ compiler. AFAIK, the minimum version would be
 gcc8, one of the compiler I proposed to have in the list. At the end I
 don't know if this needs all up to gcc14 to get gcc8, I lost a bit in the
 discussion @kencu. Latest I have now is 7.


 {{{
 gcc8 is known to fail. Try to install anyway? [y/N]
