我一直在尝试将 POCO 库升级到 1.9.0，这需要我升级 SSL，这更改了一些库名称。我正在使用来自 Shining Light
的 SSL (OpenSSL-Win64-110g)我能够重新编译新的 poco-1.9.0 库，包括在 vs2015 中重新编译 Crypto 和 Net_SSL_Open_SSL 指向新的 SSL (110g) 版本。
在我的项目中，我引用了新编译的 POCO 库并引用了新的 SSL 库路径。
新的 SSL 似乎已分别用 libcrypto64MT.dll 和 libssl64MT.dll 替换了 ssleay32MT.lib 和 libeay32MT.lib，因此我也更改了项目中的这些引用。
当我编译时，我收到 36 个与 Net、NetSSL 和加密库相关的 LNK2001“无法解析的外部符号”错误。 （如下所列）。
我想知道 SSL 110g 库对于 POCO 1.9 来说太新了，或者需要使用 VS2015 进行编译。但不确定。关于要检查的事情有什么想法吗？

好吧，我明白了。加密错误是因为我在 POCO 项目链接器中所做的设置没有保存；我注意到在运行编译器时，链接器的输出不包括新的 SSL 库（libcrypto.lib、libssl.lib）等。我还链接到 Crypto 和 Net_SSL 中的静态库。
关于 PocoNET 错误，我必须在链接器 add'l lib 依赖项中包含 ws2_32.lib 和 iphlpapi.lib 。我过去不必这样做。
我希望这对处于类似情况的人有所帮助。
