Introduction

This wiki explains how to download and install 64-bit and 32-bit gfortran.

We recommend that you code using the latest 64-bit gfortran. 32-bit gfortran is only intermittently updated and may be discontinued in the future. However, 32-bit gfortran remains available at IGPP to run legacy code.
