You can use update-alternatives to select the C/C++ compiler version.
First, you set up each version.
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 7
--slave /usr/bin/g++ g++ /usr/bin/g++-7
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-8 8
--slave /usr/bin/g++ g++ /usr/bin/g++-8
Then you select which one is the system default.
sudo update-alternatives --config gcc

Hail,
What is the recommended method to set the gcc compiler used by
PyBOMBS in building with gnuradio.lwr (gitbranch: maint-3.9)?
I am trying to trace back problems but first should use 8.2.1 (installed
as /usr/bin/gcc-8) as opposed to the system gcc which is 7.5.0. I
assume that CMAKE_CXX_COMPILER_VERSION must be defined somewhere.
