我正在尝试使用boost ASIO进行SSL工作。我在Windows上使用MingW 6.3。
当我尝试将它们链接到项目时，我使用MingW构建了OpenSSL 1.1,1.0和0.8我总是得到不同的错误（取决于缺少的内容）。 现在我正在努力使OpenSSL 1.1.0g工作，但我有这些错误，即使我手动给CMAKE的libs路径：
如果我使用OpenSSL 1.1.0g构建我的项目，这就是错误：

我使用的是错误的OpenSSL版本吗？我不应该使用OpenSSL吗？我错了吗？
编辑： 添加了-ldl和-lpthread，但没有帮助。
答案 0 :(得分：0)
我遇到了这个问题，因为我不小心使用了opensl的x86（32位）版本 （来自https://www.nuget.org/packages/openssl-vc141/，但未说明计算机） 并使用x64 boost asio将其链接到我的x64项目中。
VS2017已编译，并且仅在链接期间抱怨缺少两个符号：
LNK2001 unresolved external symbol CONF_modules_unload
LNK2001 unresolved external symbol ERR_reason_error_string
Dumpbin显示了这些符号的存在，但随后我看到该符号（和整个库）是针对x86编译的... facepalm ;很奇怪，链接程序不会抱怨不同的机器...
我切换到此版本，并且所有编译/链接均正确：
