Recently, Cython has written *. pyx extension, compiled it into a C file, and finally converted it into a so extension for python reference.
Use distutils to compile and createSetup. pyScript
From distutils. core import setup
From distutils. extension import Extension
From Cython. Distutils import build_ext
Setup (
Name = 'cython _ build_test ',
Using class = {'build _ ext ': build_ext },
Ext_modules = ext_modules
)
Parameters of the setup function:
1. name
The egg file under the site-package installation directory:/usr/lib64/python2.6/site-packages/cython_build_test-0.0.0-py2.6.egg-info. If not specified, it will be named with UNKNOW: /usr/lib64/python2.6/site-packages/UNKNOWN-0.0.0-py2.6.egg-info
2. packages tells Distutils to process those packages (including_ Init _. pyFolder)
3,Package_dirsTell Distutils which directories the files are mapped to which source package. For example, package_dir = {'': lib} indicates that all modules in" root package "are in the lib directory 4,Ext_modulesIs a list of Extension instances. The Extension definition also has some parameters, which are defined as follows:
5,Ext_packageDefine the relative path of extension
6. requires defines the dependent modules
7,ProvidesDefine which modules can provide Dependencies
8,ScriptsSpecifies the python source code file, which can be executed from the command line. Specify-install-script during installation
9,Package_dataIt usually contains some data files related to the package implementation or files similar to readme. If no template is provided, it will be added to the MANIFEST file.
10. data_files specify other files (such as configuration files)
For more information about the ext_modules parameters, see:

5. library_dirs

A list composed of database names (not file names or paths)

At this point:
Automatically created in the current directory:
Build directory
Go to the build Directory, which has a directory: temp. linux-x86_64-2.6, the directory contains the import_cython_c_math.o file, the file is the c Code Compiled after the object file containing the 0, 1 command (that is, the c language compiled file)
Import_cython_c_math.so, followed by generating a dynamic link library directly referenced by python, which is a link file
Now you can reference the library file in python.
