## Building On Ubuntu 16.04 and older systems
Some older compilers may not be able to compile modern code, such as gcc 5.4 which comes with Ubuntu 16.04 by default. Here is how to install gcc 7 on Ubuntu 16.04:
sudo add-apt-repository ppa:ubuntu-toolchain-r/test && \
apt update && \
apt-get install -y gcc-7 g++-7 && \
update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-7 60 && \
update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 60
## Run a HUSH Node
