The function pyximport.install() can take several arguments to Variable called foo as a string, and then callĬythonize(., aliases=.ĭepfile – produce depfiles for the sources if True. You can then do # distutils: include_dirs = MY_HEADERS,įind the value of MY_HEADERS in the setup.py, put it in a python static_libs/include/īut this path isn’t always fixed and you want to find it when running As an example, say youĭirective # distutils: include_dirs =.

To use, you can use aliases and pass a dictionary mapping those aliases butĬan only know at compile time (when running the setup.py) which values Nthreads – The number of concurrent builds for parallel compilationĪliases – If you want to use compiler directives like # distutils. Module names explicitly by passing them into the exclude option.

(as long as it can be converted to JSON). This metadata is only usedįor debugging purposes, so you can put whatever you want in there (extension, metadata), where extension is the createdĮxtension and metadata is metadata which will be writtenĪs JSON at the top of the generated C files. The function create_extension must return a 2-tuple Template is the Extension object given as input to CythonĪnd kwds is a dict with all keywords which should be used This function takes 2 arguments template and kwds, where
The sources, dependencies and # distutils directives but before the To create the final Extension object after Cython has processed To do this, you can provide a custom function create_extension Sometimes this is not enough and you need finer customization of the h and library files when linking to external libraries. Some useful options to know aboutĪre include_dirs, libraries, and library_dirs which specify where The Extension class takes many options, and a fuller explanation canīe found in the setuptools documentation. pxd source file using a special comment block at the start of the file:įrom setuptools import Extension, setup from Cython.Build import cythonize sourcefiles = extensions = setup ( ext_modules = cythonize ( extensions ) ) Pkg-config to determine them) you can also provide them directly in your If your options are static (for example you do not need to call a tool like To prevent this, include zip_safe=False in the arguments to setup(). When you try to use them from a dependent package. Note also that if you use setuptools instead of distutils, the defaultĪction when running python setup.py install is to create a zippedĮgg file which will not work with cimport for pxd files Note that when using setuptools, you should import it before Cython, otherwise,īoth might disagree about the class to use here. Extension ( "*", , include_dirs =, libraries =, library_dirs = ), ] setup ( name = "My hello app", ext_modules = cythonize ( extensions ), ) System, for example, it might look similar to this:įrom setuptools import Extension, setup from Cython.Build import cythonize extensions =, include_dirs =, libraries =, library_dirs = ), # Everything but primes.pyx is included here. Writing extension modules should have some details for your system. c files will varyĭepending on your operating system and compiler.
