【python】如何将python程序封装为cpython的库

python程序在发布时，往往会打包为cpython的库，并且根据应用服务器的不同架构（x86/aarch64），以及python的不同版本，封装的输出类型也是非常多。本文介绍不同架构指定python下的代码打包方式：

首先，了解应用服务器的结构，linux在终端输入

uname -m

确定是x86还是aarch64

以编译目标为aarch64+python3.8为例

from Cython.Build import cythonize
from Cython.Distutils import build_ext
from distutils.core import setupclass BuildExtWithNewSuffix(build_ext):def get_ext_filename(self, ext_name):filename = super().get_ext_filename(ext_name)return filename.replace(self.oldSuffix, self.newSuffix)def main(compileType, deviceType):if compileType == 'aarch64':BuildExtWithNewSuffix.newSuffix = 'cpython-38-aarch64-linux-gnu'# os.environ['CC'] = '/opt/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc'# os.environ['LDSHARED'] = '/opt/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc -shared'print("aarch64 compile ")setup(ext_modules=cythonize(module_list, nthreads=20,compiler_directives={'language_level': "3"}, build_dir=build_code),script_args=["build_ext", "-j10", "-b", build_target, "-t", build_tmp_dir],include_dirs=['/opt/cross_compile/rk/include/python3.8'],cmdclass={'build_ext': BuildExtWithNewSuffix})if __name__ == "__main__":compileType = 'aarch64'if (len(sys.argv) > 1):compileType = sys.argv[1]deviceType = 'atlas'if (len(sys.argv) > 2):deviceType = sys.argv[2]sys.exit(main(compileType, deviceType))
