How to install Gfortran 9, 10 or 11 on Ubuntu 20.04 LTS
October 7, 2021
For Version 10
sudo apt install gfortran-10
For Gfortran Version 11 and other latest one in development:
However, currently while writing the article Gfortran version 11 was not available in the default repository of Ubuntu 20.04. Hence, if you want that then can add a PPA.
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt install gfortran-11
On Windows I use gfortran 12 from equation.com. How do you install gfortran 12 on Ubuntu?
