Link VS2017 的 NanoMsg 错误

Question

我正在尝试在 windows 盒子上构建下一代 nanomsg (https://github.com/nanomsg/nng)。我正在使用 VS2017。 CMAKE 就像一个魅力。

我收到 link 错误。我已验证 nng.lib 文件位于：

D:\Source\LinkWareMessageBus\nng\lib

Dumbin.exe 表示符号都已就位（并且没有编译或 link 错误）

Linker/General/Additional 库目录是：D:\Source\LinkWareMessageBus\nng\lib

.h 文件读取正常。但我收到以下 link 错误：

Severity    Code    Description Project File    Line    Suppression State

这些是我的 VS2017 设置（x64 .lib 和 x64 项目）。

我还附上 nng.lib 文件中符号的 dumpbin。

我怀疑 VS2017 没有正确配置以找到 .lib（除了将路径添加到 linker/additional 库）我应该怎么做？

nng.lib symbols

更新

我不再说这个简单了。但我确实走得更远，也许你能帮助我越过终点线。即使我告诉 VS2017 在哪里可以找到 nng.lib（路径和名称）。我还尝试将它与 kernel32.lib user32.lib 和其他强制性库一起放入。

好的。我现在不再收到有关 nng_xxxx 符号的错误。相反，它现在抱怨 nng.lib 正在寻找的符号。

您要查找的符号（基于更新）是在 ws2_32.lib 中找到的 Winsock 函数。
