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
--with-openssl-rpath=[DIR|auto|no]
Set runtime library directory (rpath) for OpenSSL
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

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