第一种办法:
- 执行命令:cython test.py
- 结果:会在同一目录下面生成test.c文件
- 执行命令: gcc -c -fPIC -I /usr/include/python2.7 test.c
- 结果: 在同一目录下面生成test.o文件
- 执行命令: gcc -shared test.o -c test.so
- 结果: 在同一目录下面生成test.so文件
最后,生成的test.so文件就是需要的文件
第二种办法:
[setup.py]
from distutils.core import setup
from Cython.Build import cythonize
setup(
name = "test",
ext_modules = cythonize("test.py")
)
- 执行命令: python setup.py build_ext --inplace
第二种办法是对单独文件进行编译,下面介绍一种批量的办法:
#-*- coding:utf-8 -*-_
import os
import re
from distutils.core import Extension, setup
from Cython.Build import cythonize
from Cython.Compiler import Options
# __file__ 含有魔术变量的应当排除,Cython虽有个编译参数,但只能设置静态。
exclude_so = ['__init__.py', 'run.py']
sources = 'backend'
extensions = []
remove_files = []
for source,dirnames,files in os.walk(sources):
for dirpath, foldernames, filenames in os.walk(source):
if 'test' in dirpath:
break;
for filename in filter(lambda x: re.match(r'.*[.]py$', x), filenames):
file_path = os.path.join(dirpath, filename)
if filename not in exclude_so:
extensions.append(
Extension(file_path[:-3].replace('/', '.'), [file_path], extra_compile_args = ["-Os", "-g0"],
extra_link_args = ["-Wl,--strip-all"]))
remove_files.append(file_path[:-3]+'.py')
remove_files.append(file_path[:-3]+'.pyc')
Options.docstrings = False
compiler_directives = {'optimize.unpack_method_calls': False, 'always_allow_keywords': True}
setup(
# cythonize的exclude全路径匹配,不灵活,不如在上一步排除。
ext_modules = cythonize(extensions, exclude = None, nthreads = 20, quiet = True, build_dir = './build',
language_level = 2, compiler_directives = compiler_directives))
# 删除py和pyc文件
for remove_file in remove_files:
if os.path.exists(remove_file):
os.remove(remove_file)
- 执行命令: python setup.py build_ext --inplace
- 结果:最后生成.so文件,删除中间结果。
重点提一下,在编译flask代码时,遇到问题,报错:参数不够(大体意思是这样,错误未截图),在compiler_directives中添加: {always_allow_keywords:True}
