Minpack Python bindings

Python bindings for Minpack.

Building the extension module

To perform a build some version of minpack has to be available on your system and preferably findable by pkg-config. Try to find a minpack installation you build against first with

pkg-config --modversion minpack

Adjust the PKG_CONFIG_PATH environment variable to include the correct directories to find the installation if necessary.

Using pip

This project support installation with pip as an easy way to build the Python API.

  • C compiler to build the C-API and compile the extension module (the compiler name should be exported in the CC environment variable)
  • Python 3.6 or newer
  • The following Python packages are required additionally

Make sure to have your C compiler set to the CC environment variable

export CC=gcc

Install the project with pip

pip install .

If you already have a minpack installation, e.g. from conda-forge, you can build the Python extension module directly without cloning this repository

pip install "https://github.com/fortran-lang/minpack/archive/refs/heads/main.zip#egg=minpack&subdirectory=python"

Using meson

This directory contains a separate meson build file to allow the out-of-tree build of the CFFI extension module. The out-of-tree build requires

  • C compiler to build the C-API and compile the extension module
  • meson version 0.53 or newer
  • a build-system backend, i.e. ninja version 1.7 or newer
  • Python 3.6 or newer with the CFFI package installed

Setup a build with

meson setup _build -Dpython_version=$(which python3)

The Python version can be used to select a different Python version, it defaults to 'python3'. Python 2 is not supported with this project, the Python version key is meant to select between several local Python 3 versions.

Compile the project with

meson compile -C _build

The extension module is now available in _build/minpack/_libminpack.*.so. You can install as usual with

meson configure _build --prefix=/path/to/install
meson install -C _build
