macos编译openssl

openssl是加解密经常用到的的一个开源库，很多项目中有用到，比如账号登录，数据库加密，libcurl访问https等，一般我们用到的是在window平台，而且很多都可以在网上找到现成的库，在macos系统用到的比较少，可能是开发少的原因。本篇介绍在macos中编译openssl.

macos系统版本10.15.6

1.到官网下载openssl源码

/source/old/1.1.1/index.html

这里下载的是openssl-1.1.1d 的版本

解压

chenyj-imac:openssl-1.1.1d chenyj$  tar -zxf openssl-1.1.1d.tar.gz 

切换到openssl-1.1.1d目录

编译配置

chenyj-imac:openssl-1.1.1d chenyj$ ./config -fPIC no-shared --prefix=/usr/local

Operating system: x86_64-apple-darwinDarwin Kernel Version 19.6.0: Thu Jun 18 20:49:00 PDT 2020; root:xnu-6153.141.1~1/RELEASE_X86_64
