In this comprehensive guide, we will walk you through the process of checking and upgrading your gfortran version on Ubuntu. The GNU Fortran compiler, or gfortran, is a part of the GNU Compiler Collection (GCC). It is crucial to keep your gfortran updated to ensure compatibility and functionality with the latest Fortran language standards.
To check your gfortran version on Ubuntu, open your terminal and type "gfortran –version". To upgrade gfortran, first update your package list with "sudo apt-get update" and then install the latest version with "sudo apt-get install gfortran". Verify the installation by checking the version again.
Checking Your gfortran Version
Before you proceed with upgrading gfortran, it’s essential to check the current version installed on your Ubuntu system. You can do this by using the command line. Here’s how:
- Open your terminal. You can do this by pressing
Ctrl + Alt + Tor by searching for ‘Terminal’ in your system’s application launcher.
- In the terminal, type the following command and press
This command will display the version of gfortran installed on your system. The
--version parameter is used to request the version information of the installed gfortran. The output might look something like this:
GNU Fortran (Ubuntu/Linaro 4.6.1-9ubuntu3) 4.6.1
If your gfortran version is outdated, you might want to upgrade it to the latest version. Here is a step-by-step guide on how to do this:
Step 1: Update the Package List
Firstly, it’s good practice to update your package list before installing any new software. This ensures that you are downloading the latest version available in the repositories. To do this, use the following command:
sudo apt-get update
sudo command allows you to run commands with superuser privileges, while
apt-get update fetches the package lists from the repositories and updates them.
Step 2: Install the Latest gfortran
After updating your package list, you can install the latest version of gfortran using the following command:
sudo apt-get install gfortran
apt-get install command is used to install new software. In this case, it installs the latest version of gfortran available in the repositories.
Step 3: Verify the Installation
Once the installation is complete, you should verify that the latest version of gfortran has been installed correctly. You can do this by checking the version of gfortran again, as explained in the first section of this article.
Keeping your gfortran compiler updated is crucial for maintaining compatibility with the latest Fortran standards. This guide has shown you how to check your current gfortran version and how to upgrade it to the latest version available in the Ubuntu repositories.
gfortran is the GNU Fortran compiler, which is a part of the GNU Compiler Collection (GCC). It is used to compile and run Fortran programs on Ubuntu and other Linux systems.
It is important to keep gfortran updated to ensure compatibility and functionality with the latest Fortran language standards. Updates often include bug fixes, performance improvements, and support for new features introduced in newer versions of Fortran.
To check the version of gfortran installed on your Ubuntu system, open the terminal and type the command
