Installing gcc-7.2 via apt

by

how do I install gcc-7.2 via apt on zesty? Anything I found is either installing 7.0.1 or for installing gcc on Ubuntu 16.10

Answer

The Ubuntu maintainers have some alpha-quality/unsupported gcc 7.2 packages that might work. Use at your own risk

$ gcc-7 -v
...
gcc version 7.2.0 (Ubuntu 7.2.0-1ubuntu1~16.04)
$

Install it (should work on Trusty to Zesty)

sudo env DEBIAN_FRONTEND=noninteractive                                    \
     bash -c 'apt-get install -y python-software-properties lsb-release && \
            echo -e "Package: gcc-7\\nPin: release n=$(lsb_release -sc)\\nPin-Priority: 990" > /etc/apt/preferences.d/gcc-7 \
            apt-add-repository -yu ppa:ubuntu-toolchain-r/test &&              \
            apt-get install -y gcc-7'
