library0.14.2.19pypypi✓ verified 84d ago

fckitlib is a Python library designed to build Python modules on top of existing Fortran codebases. It provides utilities for seamless argument passing, handling Fortran derived types and allocatable arrays, and logging within Fortran components. It is primarily used in scientific computing, particularly with models developed by ECMWF. The current version is 0.14.2.19, with active development and frequent releases (multiple per year), typically supporting Python 3.7+.

✓ from fckitlib import findlibs_dependencies

✗ from fckit.log import Logger

This quickstart demonstrates initializing `fckitlib`'s pure Python-side logger. It also includes a conceptual example of loading the `fclib` Fortran example module, which requires `fckitlib` to be built with Fortran support and correctly installed, allowing Python to interface with compiled Fortran functions and types.

from fckit.log import Logger # Initialize a pure Python-side logger provided by fckitlib # In a full Fortran-interfaced application, this logger could # be configured to be accessible from the Fortran side as well. logger = Logger("my_fckit_app") logger.info("fckitlib Logger initialized successfully!") logger.warning("This is a Python-side log message.") # Example of attempting to load the fckitlib Fortran example module # This part is conceptual; actual Fortran interaction requires fckitlib # to be built with Fortran support and correctly linked. try: from fckit import fclib print(f"\nfckitlib fclib module loaded. Fortran version: {fclib.version_str()}") # Further interaction with Fortran functions/types from fclib would go here except ImportError: print("\nWarning: fckit.fclib module not found. It might not be built or installed correctly with Fortran support.") except Exception as e: print(f"\nError loading fckit.fclib: {e}")

Debug

Known issues

breakingThe signature of `fckit_c_call_fortran` changed, which is a breaking change for users implementing custom Fortran wrappers or C interfaces.

fix

Review the `CHANGELOG.md` and `fckitlib` C API documentation. Update any custom C interfaces or Fortran wrappers to match the new `fckit_c_call_fortran` signature.

affects: >=0.13.0

breakingThe `fckit.cxx` module was renamed to `fckit.cpp` to better reflect its purpose and avoid confusion.

fix

Update all import statements and references from `fckit.cxx` to `fckit.cpp` in your Python code.

affects: >=0.11.0

breakingThe `string_ptr` type was moved from `fckit.fclib.types` to `fckit.types` for broader applicability.

fix

Change import paths for `string_ptr` from `from fckit.fclib.types import string_ptr` to `from fckit.types import string_ptr`.

affects: >=0.12.0

gotchaInstallation and runtime of `fckitlib` often require a Fortran compiler (e.g., gfortran) and specific environment setup (e.g., `LD_LIBRARY_PATH` on Linux/macOS, `PATH` on Windows) for linked Fortran libraries to be found. Compilation issues are common if the environment is not correctly configured.

fix

Ensure a compatible Fortran compiler is installed and accessible. Consult the `fckitlib` documentation and your operating system's guidelines for setting up shared library paths, especially when building from source or linking to external Fortran libraries.

affects: all
