即使安装了libssl，Qt也找不到libssl。

想要解决这个问题好几个小时。我的Qt程序依赖于https连接，但in不能在Arch上启动它( Debian和Ubuntu可以很好地工作)。
I向LD_LIBRARY_PATH LD_LIBRARY_PATH=home/michal/Qt/5.10.0/gcc_64/lib:/home/michal/Qt/5.10.0/gcc_64/lib:/usr/lib添加/usr/lib
程序输出

}输出为

在我将Ubuntu16.x升级到18.04之后，我遇到了同样的问题。原因似乎是新Ubuntu上的默认libssl版本为1.1.0，而Qt的预构建二进制文件到目前为止预期为1.0.0 (有关此问题的更多细节，请参见https://bugreports.qt.io/browse/QTBUG-68156 )。
我的解决办法如下。
- 切换到Qt可执行文件的目录。
- 创建一个指向libssl版本1.0.0的符号链接 -s /usr/lib/x86_64-linux-gnu/libssl.so.1.0.0 libssl.so
- 确保您的LD_LIBRARY_PATH包含1中的目录。
现在，启动您的Qt可执行文件将选择正确的libssl版本。

我需要重新安装Ubuntu，并安装OpenSSL1.0.x版本，而不是1.1.x版本。此外，如果需要，您可以在构建项目之前运行export LD_LIBRARY_PATH=/path/openssl/lib。

我在Ubuntu16.04的QT5.10.1上也有同样的问题。我刚刚在我的机器上编译了Qt并安装了它，这个解决了ssl问题，甚至开始使用opnessl 1.1.0。我已经配置了Qt无-openssl链接标志。考虑到编译可能会花费大量的时间，2-4小时。
