pkgconfig 1.6.0

Interface Python with pkg-config

pkgconfig is a Python module to interface with the pkg-config command-line tool for Python 3.9+.

The pkg-config command-line tool typically comes from a package either called pkg-config (the original implementation) or pkgconf (a more recent, improved reimplementation intended as a drop-in replacement).

The pkgconfig module can be used to

• find all pkg-config packages

  >>> packages = pkgconfig.list_all()

• check if a package exists

  >>> pkgconfig.exists('glib-2.0')
  True

• check if a package meets certain version requirements

  >>> pkgconfig.installed('glib-2.0', '< 2.26')
  False

• return the version

  >>> pkgconfig.modversion('glib-2.0')
  '2.56.3'

• query CFLAGS and LDFLAGS

  >>> pkgconfig.cflags('glib-2.0')
  '-I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include'
  
  >>> pkgconfig.libs('glib-2.0')
  '-lglib-2.0'

• get all variables defined for a package:

  >>> pkgconfig.variables('glib-2.0')
  {u'exec_prefix': u'/usr'}

• parse the output to build extensions with setup.py

  >>> d = pkgconfig.parse('glib-2.0 gtk+-2.0')
  >>> d['libraries']
  [u'gtk+-2.0', u'glib-2.0']

  or

  >>> ext = Extension('foo', ['foo.c'])
  >>> # sets extension attributes as needed
  >>> pkgconfig.configure_extension(ext, 'glib-2.0 gtk+-2.0')

  The pkgconfig.parse function returns a dictionary of lists. The lists returned are accurate representations of the equivalent pkg-config call’s results, both in content and order.

If pkg-config is not on the PATH, an EnvironmentError is raised.
