Re: setting gcc compiler in pybombs

[Ron Economos]

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
