Question

我正在尝试在Windows框上构建nanomsg下一代（https://github.com/nanomsg/nng）。我正在使用VS2017。 CMAKE就像一种魅力。

我收到链接错误。我已验证nng.lib文件位于：

D：\ Source \ LinkWareMessageBus \ nng \ lib

Dumbin.exe表示符号都已放置到位（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。但是我收到以下链接错误：

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VS2017没有正确配置以找到.lib（除了将路径添加到链接器/附加库之外）我应该怎么办？

nng.lib symbols

更新

我不再说这很简单。但是我确实走得更远，也许您可以帮助克服终点线。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和其他必需的库一起放入。

好。我现在不再遇到有关nng_xxxx符号的错误。而是现在它正在抱怨nng.lib正在寻找的符号。

参见下文：

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