python3.10在centos7上构建

概述

在centos7上安装py3.10,用到openssl库

env

  • centos7.8
  • Python-3.10.7.tgz

link

01 下载Python3.10.7

02 requirement

yum install -y gcc gcc-c++ make autoconf

yum insall -y zlib-devel bzip2-devel ncurses-devel sqlite-devel readline-devel  libffi-devel

require openssl-1.1.1+,需要自编译

03 install openssl

./config -fPIC --prefix=/usr/local/openssl
make -s -j4
make -s install -j4

注释:
--prefix:指定安装目录
-fPIC:编译openssl的静态库

04 building-py

tar zxf Python-3.10.7.tgz   && cd Python-3.10.7


//view configure help
./configure --help

  --with-system-ffi       build _ctypes module using an installed ffi library,
                          see Doc/library/ctypes.rst (default is
                          system-dependent)
...
  --with-openssl=DIR      root of the OpenSSL directory

                          libraries, no (default): don't set rpath, auto:
                          auto-detect rpath from --with-openssl and

//编译过程提示错误,因此需要安装openssl-1.1.1+
Failed to build these modules:
_hashlib              _ssl                                     

Could not build the ssl module!
Python requires a OpenSSL 1.1.1 or newer

//编译构建
./configure -q --prefix=/usr/local/python3.10.7 --with-openssl=/usr/local/openssl --with-openssl-rpath=auto

make -s -j4  && make -s -j4 install

py3.10.7/bin/xxx   //部分whl安装后可执行文件会在这里存在

01 install libffi-devel
02 enable openssl and version
03 again buiding py3.10
