我在 Rust 中遇到链接问题。 我是 Rust 新手，正在使用 pcap 板条箱构建一个库项目。 在 Linux 和 Mac OS 上一切正常，但当我在 Windows 上尝试时，我遇到链接错误。
我在cargo.toml中添加了pcap板条箱作为依赖项。 然后，我按照 crates.io pcap 页面 (https://crates.io/crates/pcap) 中所述安装了 Winpcap（还安装了开发人员包）。然后在页面上显示：
Add the /Lib or /Lib/x64 folder to your LIB environment variable.
我收到此错误（我删除了错误中间的部分路径以专注于主要内容，但如果它们有用，请告诉我）：
error: linking with `link.exe` failed: exit code: 1181

= note: "C:\\Program Files\\Microsoft
VisualStudio\\2022\\Community\\VC\\Tools\\MSVC\\14.........
....................
= note: LINK : fatal error LNK1181: cannot open input file
'wpcap.lib'
我通过将 wpcap.lib 基本链接错误添加到名为 LIB 的新环境变量（如文档所述）来解决它。
然后，尝试进行货物构建时，我收到一条错误消息
PS C:\dev\testing> cargo build

好像找到了wpcap.lib，但是没有找到那3个libpcap函数。 我被困住了。感谢您的关注和回复:)
更新。我解决了卸载 winpcap 和 rustup 的问题。 重新安装了 rustup、winpcap 和 winpcap 开发者包 sdk。 将 winpcap sdk 的 x64 文件夹路径添加到新的 LIB 环境变量中。 现在一切正常了。我不知道我之前遇到这个错误的原因，但知道它有效。
