What it is and what it does
FCKit is a Fortran toolkit designed to simplify interoperability between Fortran and C/C++ codebases. It includes a unit testing framework (fctest) that uses C preprocessor macros to streamline test writing, bundling tests into Fortran modules and auto-generating a main program via Python and CMake. The package also wraps useful algorithms from ecKit and provides Fortran modules for MPI and logging in mixed-language applications.
The package is distributed as pre-built wheels for multiple Python versions and platforms (macOS and Linux), but its primary use is within CMake-driven Fortran build systems rather than as a standalone Python library. Installation involves medium friction due to compiled dependencies and platform-specific wheels. It is actively maintained and carries no known security vulnerabilities.
Use it for
- Writing unit tests for Fortran code using preprocessor macros and CMake integration without manual boilerplate.
- Building mixed Fortran/C++ applications that need MPI communication and logging infrastructure.
- Wrapping ecKit algorithms in Fortran for numerical or scientific computing workflows.
- Offline deployment of Fortran projects by pre-downloading platform-specific wheels for air-gapped systems.
