Fortran

Last modified: 06 November 2021

CLion supports Fortran via the plugin compatible with all IntelliJ-based IDEs. This plugin includes smart editor, navigation actions, code analysis and debugger for FORTRAN 77/90/95/2003/2008 source code. Application support is provided via CMake.

tip

The Fortran plugin is currently under development, and your feedback is welcome in the projects's GitHub tracker.

tip

You can find a sample Fortran project build with CMake in this wiki.

Start a Fortran project in CLion

  1. Install the Fortran plugin either directly from the Plugin Repository page or from CLion: go to Settings / Preferences | Plugins, switch to Marketplace and type Fortran in the search field, then click Install in the plugin description dialog.

  2. Create a new Fortran executable project (File | New Project) or open an existing CMake-based Fortran project.

  3. Make sure to instruct CMake on where to find the Fortran compiler. You can do so by setting the FC environment variable or set CMAKE_Fortran_COMPILER in CMakeLists.txt (provide the full path to the compiler executable or only the compiler name in case the PATH variable is set accordingly).

tip

GNU Fortran compiler is included in the GCC installation, or you can use other Fortran compilers of your choice.

Working with Fortran code

In addition to parsing and highlighting your Fortran code, the plugin provides other code insight features, for example:

  • Code editing: Add Line Comment Ctrl+/, Code folding, Brace matching, and Formatting (currently available only for free source form files)

    Code styles for Fortran

  • Navigation actions: Go to Definition, Structure view, and Find Usages

    Find Usages for Fortran

  • Code analysis: a set of useful code inspections to catch potential errors
