1 前言

一个问题，一篇文章，一出故事。
由于笔者需要编译uw-imap而去编译低版本的openssl，于是整理此章节。
如果你需要参阅如何编译安装openssl，请参阅如下章节，

如何编译安装openSSL？

2 最佳实践

2.1 解压安装包

tar -xf openssl-1.1.1k.tar.gz

2.2 预编译安装包

cd openssl-1.1.1k/
./config --prefix=/usr/local/openssl-1.1.1k --openssldir=/usr/local/openssl-1.1.1k shared zlib-dynamic

如果你遇到如下错误提示，

Operating system: x86_64-whatever-linux2
Can't locate FindBin.pm in @INC (you may need to install the FindBin module) (@INC contains: /usr/local/lib64/perl5/5.32 /usr/local/share/perl5/5.32 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5) at ./Configure line 15.

This system (linux-x86_64) is not supported. See file INSTALL for details.

你可能需要使用如下命令解决依赖关系，

dnf install perl perl-ExtUtils-MakeMaker

2.3 编译安装包

make
make install
