Fortran

Last modified: 11 January 2023

CLion supports Fortran via the Fortran plugin. The plugin provides language support and debugger for FORTRAN 77/90/95/2003/2008. Application support is provided by CMake.

tip

The Fortran plugin is currently under development. You can share your feedback or submit a request in the projects's GitHub tracker.

tip

Find a sample Fortran project build with CMake in this wiki.

Start a Fortran project in CLion

  1. Install the Fortran compiler. You can use GNU Fortran compiler included in the GCC installation or another Fortran compilers of your choice.

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

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

note

To instruct CMake on where to find the Fortran compiler, set the FC or CMAKE_Fortran_COMPILER environment variable in your CMakeLists.txt (provide the full path to the compiler executable or only the compiler name in case the PATH variable is set accordingly). See CMake documentation for details.

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
