How to install latest gcc on Linux Mint 18 (18.3)
These commands are based on a askubuntu answer http://askubuntu.com/a/581497 and https://askubuntu.com/questions/26498/choose-gcc-and-g-version
To install gcc-7 (gcc-7.2.0), I had to do more stuff as shown below.
USE THOSE COMMANDS AT YOUR OWN RISK. I SHALL NOT BE RESPONSIBLE FOR ANYTHING.
ABSOLUTELY NO WARRANTY.
If you are still reading let's carry on with the code.
sudo apt-get update && \
sudo apt-get install build-essential software-properties-common -y && \
sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y && \
sudo apt-get update && \
sudo apt-get install gcc-snapshot -y && \
sudo apt-get update && \
sudo apt-get install gcc-7 g++-7 gcc-6 g++-6 gcc-multilib -y && \
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 70 --slave /usr/bin/g++ g++ /usr/bin/g++-7 && \
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-6 60 --slave /usr/bin/g++ g++ /usr/bin/g++-6 && \
sudo apt-get install gcc-5 g++-5 -y && \
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 50 --slave /usr/bin/g++ g++ /usr/bin/g++-5;
When completed, you must change to the gcc you want to work with by default. Type in your terminal:
sudo update-alternatives --config gcc
To verify if it worked. Just type in your terminal
gcc -v
If everything went fine you should see gcc 7.2.0 by the time I am writing this gist
Happy coding!
