qt.network.ssl: Incompatible version of OpenSSL
主要是 openssl 版本不兼容系统自带的1.1.1d 的问题 下载地址

/source/old/1.1.1/index.htmlhttps://www.openssl.org/source/old/1.1.1/   tar zxvf openssl-1.1.1k.tar.gz 
   cd openssl-1.1.1k/
   ls
   ./config enable-shared
   make depend
   make
  make test
当make test  的时候会有一个错误

openssl Can't locate Test/Harness.pm in @INC

以下是解决方案 创建一个.sh文件 sudo 运行 会安装相关的应用

openssl@1.1: Can't locate Test/Harness.pm in @INC on CentOS 8 · Issue #20079 · Homebrew/linuxbrew-core · GitHub

#!/bin/sh
 
set -ex
 
yum -y --nogpgcheck install which
yum -y groupinstall 'Development Tools'
yum -y install curl \
               file \
               git \
               perl-CPAN \
               perl-Module-Load-Conditional \
               perl-core \
               gnupg2
yum clean all

完后在make test 就不会报错了，（但还是有No external tests in this configuration）这些不用管

直接

sudo make install

 把下面的 .so 文件拷贝到 qt对应的 gcc_64/lib 目录下

然后在编译运行
