【中文标题】Boost 1_65_1 不能用 OpenSSL 1.1.0g “未定义的参考”编译，但用“nm”找到【英文标题】：Boost 1_65_1 doesn't compile with OpenSSL 1.1.0g "undefined reference" but find with "nm" 【发布时间】：2018-04-18 17:14:10 【问题描述】：

我正在尝试使 SSL 与 boost ASIO 一起工作。我在 Windows 上并使用 MingW 6.3。

我使用 MingW 构建了 OpenSSL 1.1、1.0 和 0.8，当我尝试将它们链接到项目时，我总是遇到不同的错误（取决于缺少什么）。现在我正在尝试使 OpenSSL 1.1.0g 工作，但即使我使用 CMAKE 手动提供库的路径，我也会遇到这些错误：

如果我使用 OpenSSL 1.1.0g 构建我的项目，这就是错误：

我编译的 OpenSSL 库的 nm：

0000000000004de0 T ERR_reason_error_string

我是否使用了错误的 OpenSSL 版本？我不应该使用 OpenSSL 吗？我是不是建错了？

编辑：添加了 -ldl 和 -lpthread 但这没有帮助。

【问题讨论】：

你不能使用boost库的binary distribution吗？ @user23573 我使用的是 MingW，因此使用的是 *.a 而不是 *.lib。我没有找到任何带有 zlib、openssl 等的 mingw 预编译提升。一切正常，但是当我包含 OpenSSL 时，我遇到了问题。显示你的链接命令。 @n.m.我使用 CMAKE 并使用 find_library 手动导入它（因为我构建了它），我用我的 CMAKE 进行了更新啊，CMAKE的美。让您完全摆脱对图书馆的各种担忧，是吗？ 【参考方案1】：

我遇到了这个问题，因为我不小心使用了 x86（32 位）版本的 openssl （来自https://www.nuget.org/packages/openssl-vc141/ 没有说明机器）并将其与 x64 boost asio 链接到我的 x64 项目中。

VS2017 已编译，仅在链接时抱怨缺少两个符号：

LNK2001 unresolved external symbol CONF_modules_unload  
LNK2001 unresolved external symbol ERR_reason_error_string

Dumpbin 显示这些符号存在，但后来我看到该符号（以及整个库）是为 x86 编译的... facepalm;奇怪的是链接器不会抱怨不同的机器......

我切换到这个版本并且所有编译/链接都正确：

https://www.nuget.org/packages/openssl-vc140-vc141-x86_64/
