__TOC__
ubuntu 20.04 自带 openssl，但无相应的 .h 及 .so .a
 <small>openssl
 OpenSSL> version
 OpenSSL 1.1.1f  31 Mar 2020</small>

可通过安装 libssl-dev 解决
 <small>apt install libssl-dev
 需要高版本的 openssl 报如下错误
 error while loading shared libraries: libcrypto.so.3</small>

 <small># 删除，可选操作
 apt remove openssl libssl-dev
 # 以下目录及文件需手工删除
 /bin/openssl
 /bin/c_rehash
 /lib/ssl
 /usr/lib/ssl</small>

=== 安装 openssl 3 ===
 <small>apt install build-essential checkinstall zlib1g-dev -y
 
 wget https://www.openssl.org/source/openssl-3.0.8.tar.gz
 
 ./config --prefix=/usr/local/openssl --openssldir=/usr/local/openssl shared zlib
 make -j4
 make install_sw
 
 # /etc/ld.so.conf
 # add /usr/local/openssl/lib64
 # ldconfig
 
 # 配置路径
 export PATH=/usr/local/openssl/bin:$PATH
 export LD_LIBRARY_PATH=/usr/local/openssl/lib64:$LD_LIBRARY_PATH
 
 openssl version -a</small>

=== zlib or zlib-dynamic ===
 <small>./config ... shared zlib
 ./config ... shared zlib-dynamic</small>
设置 openssl 编译时使用哪个方式(静态库、动态库)来获取 zlib 依赖。
