numpy.distutils.misc_util.get_info(pkgname, dirs=None) [source]

Return an info dict for a given C library.

The info dict contains the necessary options to use the C library.

Parameters

pkgnamestr

Name of the package (should match the name of the .ini file, without the extension, e.g. foo for the file foo.ini).

dirssequence, optional

If given, should be a sequence of additional directories where to look for npy-pkg-config files. Those directories are searched prior to the NumPy directory.

Returns

infodict

The dictionary with build information.

Raises

PkgNotFound

If the package is not found.

Examples

To get the necessary information for the npymath library from NumPy:

>>> npymath_info = np.distutils.misc_util.get_info('npymath')
>>> npymath_info                                    
{'define_macros': [], 'libraries': ['npymath'], 'library_dirs':
['.../numpy/core/lib'], 'include_dirs': ['.../numpy/core/include']}

This info dict can then be used as input to a Configuration instance:

config.add_extension('foo', sources=['foo.c'], extra_info=npymath_info)

numpy.distutils.misc_util.get_pkg_info(pkgname, dirs=None) [source]

Return library info for the given package.

Parameters

pkgnamestr

Name of the package (should match the name of the .ini file, without the extension, e.g. foo for the file foo.ini).

dirssequence, optional

If given, should be a sequence of additional directories where to look for npy-pkg-config files. Those directories are searched prior to the NumPy directory.

Returns

pkginfoclass instance

The LibraryInfo instance containing the build information.

Raises

PkgNotFound

If the package is not found.

numpy.distutils.misc_util.get_num_build_jobs() [source]

Get number of parallel build jobs set by the –parallel command line argument of setup.py If the command did not receive a setting the environment variable NPY_NUM_BUILD_JOBS is checked. If that is unset, return the number of processors on the system, with a maximum of 8 (to prevent overloading the system if there a lot of CPUs).

Returns

outint

number of parallel jobs that can be run
