NanoMsg 与 VS2017 的链接错误

Question

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

我收到链接错误。我已验证 nng.lib 文件位于：

D:\Source\LinkWareMessageBus\nng\lib

Dumbin.exe 表示符号全部到位（并且没有编译或链接错误）

链接器/常规/附加库目录为：D:\Source\LinkWareMessageBus\nng\lib

.h 文件可以正常读取。但我收到以下链接错误：

Severity    Code    Description Project File    Line    Suppression State

这些是我的 VS2017 设置（x64 .lib 和 x64 项目）。

我还在 nng.lib 文件中附加了符号的转储。

我怀疑是没有正确配置 VS2017 来查找 .lib（除了添加链接器/附加库的路径）我该怎么办？

nng.lib symbols

---

更新

我不再说这很简单。但我确实走得更远，也许你可以帮助越过终点线。即使我告诉 VS2017 在哪里可以找到 nng.lib（路径和名称）。我也尝试将它与 kernel32.lib user32.lib 和其他强制库一起放入。

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

您要查找的符号（基于更新）是 ws2_32.lib 中的 Winsock 函数。
