使用VS2008 Boost ASIO和OpenSSL链接未解决的错误

我从BoostPro下载了Boost版本1.51。安装程序似乎有点不稳定，但我想我设法下载了大部分1.51文件。对于丢失的文件，我找到了另一个link，并设法下载其余的文件。我还下载了OpenSSL版本的64位64版本。我正在尝试从此example client code构建代码。链接器生成51个未解决的外部错误。这是前20个，似乎至少有些类似于其他人抱怨的错误：

我在这里已经阅读了有关将Boost与OpenSSL相关联的问题的其他问题，并尝试了建议的步骤来解决问题。这包括：

  1. 将路径C：\ OpenSSL-Win64 \ include添加到其他包含目录。
  2. 将C：\ OpenSSL-Win64 \ lib \ VC \ static添加到其他库目录。也尝试过指定C：\ OpenSSL-Win64 \ lib \ VC \路径，结果相同。
  3. 将libeay32MDd.lib和ssleay32MDd.lib添加到链接器附加依赖项的附加依赖项。

    4. 即使执行了上述操作，我仍然会收到这些链接错误。我也尝试使用__stdcall而不是默认的__cdecl来构建我的项目 - 这会在调用信号时产生编译错误，这会产生__cdecl;所以我不认为就是这样。我已经尝试了我能想到的一切。有没有人有任何想法我做错了什么或我可以尝试什么来解决这个问题？

答案 0 :(得分：1)

我终于通过构建Boost ASIO和OpenSSL库的32位版本来构建解决方案。我现在怀疑这是Windows 64位版本的Boost :: ASIO中的一个错误，并提交了bug report。

为了摆脱未解决的链接错误，还需要下载32位版本的VS2008 redistributables以及32位版本的OpenSSL，并针对32位版本的Boost构建。
