| export PYTHONHOME=/usr/bin/python
export PYTHONPATH=/usr/bin/:/usr/lib/python27.zip:/usr/lib/python2.7:/usr/lib/python2.7/plat-linux2:/usr/lib/python2.7/lib-tk:/usr/lib/python2.7/lib-old:/usr/lib/python2.7/lib-dynload:/usr/lib/python2.7/site-packages

其中 PYTHONPATH 的内容可由以下py代码得出

| import sys
print sys.path
|
一、快速转so
setup.py

| from distutils.core import setup
from Cython.Build import cythonize
# 将需要转换的py文件放入module_list
module_list = ['main.py']
setup(ext_modules=cythonize(module_list, language_level=2),
script_args=['build_ext', '--inplace'])
|
二、py带main转可执行文件
2.1、将py转c
- py文件需要带”# cython : language_level=2”或”# cython : language_level=3”

| cython --embed main.py
//等效
cython --embed -o main.c main.py
|
2.2、将c转可执行文件
2.2.1、x86-64平台
1
| x86_64-linux-gnu-gcc -O3 main.c -I /usr/include/python3.6m/ -lpython3.6m -o main
|
2.2.2、arm交叉编译平台
1
| arm-linux-gnueabihf-gcc -O3 main.c -I /opt/Crosscompile/buildComplete/python-2.7.16/include/python2.7/ -L /opt/Crosscompile/buildComplete/python-2.7.16/lib -lpython2.7 -o main-arm
|
三、py转so
3.1、将py转c
- py文件需要带”# cython : language_level=2”或”# cython : language_level=3”
1

| cython func.py
//等效
cython -o func.c func.py

3.2、将c转o
