python文件编译为so和可执行文件

1 准备setup.py文件

#!/usr/bin/env python
# encoding = utf-8
from distutils.core import setup, Extension
from Cython.Build import cythonize
import os, os.path as osp
import glob

"""
python3.7 -m pip install pycrypto
python3.7 -m pip install Cython

# 编译其他模块为so
python3.7 setup.py

# 编译入口启动脚本为 可执行文件
cython main.py --embed && \
gcc -c main.c -I/usr/include/python3.7m -o main.o && \
gcc main.o -L/usr/lib/python3.7/config-3.7m-aarch64-linux-gnu -lpython3.7m  -o main
rm -r ./*.c && rm -r ./*.o
"""

build_dir = "build_so"
build_tmp_dir = build_dir + "/temp"


skip_files = [
    'main.py'
]


def compile_to_so(pyfile):
    # compile so
    setup(
        name='export_so',
        version='1.0 build 20220818.2212',
        # single file
        ext_modules=cythonize(pyfile, nthreads=2),
        script_args=["build_ext", "-b", build_dir, "-t", build_tmp_dir]
    )
    # remove tmp files
    for f in glob.glob(f'./**/*.c', recursive=True):
        os.remove(f)


def compile_all_files():
    os.makedirs(f'./{build_dir}', exist_ok=True)
    os.makedirs(f'./{build_tmp_dir}', exist_ok=True)
    for f in glob.glob(f'./**/*.py', recursive=True):
        fname = osp.basename(f)
        if '__init__' in fname or 'setup' in fname:
            continue
        elif fname in skip_files:
            continue
        try:
            compile_to_so(f)
        except Exception as e:
            print(e)

    os.removedirs(build_tmp_dir)
    print('done.')


if __name__ == '__main__':
    compile_all_files()
    # compile_to_so('./xx/xx.py')

2  先执行setup.py 生成so文件, 生成的目录结构和原来一样

3 再执行sh命令，把入口py编译为 二进制文件

cython main.py --embed && \
gcc -c main.c -I/usr/include/python3.7m -o main.o && \
gcc main.o -L/usr/lib/python3.7/config-3.7m-aarch64-linux-gnu -lpython3.7m  -o main
rm -r ./*.c && rm -r ./*.o

#如果gcc编译失败，则使用py_compile来编译成 .pyc文件
#如果cython编译二进制执行文件失败，则使用py_compile生成.pyc  
输出位置在： ./__pycache__/xx.cpython-37.pyc
python -m py_compile xx.py
cp __pycache__/xx.cpython-37.pyc ./

启动程序：
python3.7 xx.cpython-37.pyc
