我有一个C ++项目，该项目可以编译并链接到静态curl库（7.46.0）。 我正在升级curl以支持openssl 1.1.1a。使用以下命令使用静态openssl构建curl 7.64.0。
nmake /f Makefile.vc mode=static MACHINE=x64 WITH_SSL=static ENABLE_SSPI=no ENABLE_WINSSL=no SSL_PATH=C:\openssl\1.1.1a\Win5.2_64\release
构建完成，并生成libcurl_a.lib。
现在，我继续构建链接到静态curl库的C ++应用程序。
我在这里遇到多个链接错误。

fatal error LNK1120: 198 unresolved externals
我要链接到Ws2_32.Lib Crypt32.Lib Wldap32.Lib
或者我的理解是错误的？有人可以帮我理解这里的问题吗？

静态库实际上只是对象文件的存档。更具体地说，它不是像可执行文件或DLL那样链接。
这意味着，如果您在应用程序中使用了静态库，则还必须链接其依赖项。

请注意，使用 CURL OpenSSL 构建和链接需要“技巧”（不幸的是）。
我强烈建议您使用 CURL 源的 \projects\Windows 中的即用型 VC 项目。
然而，这里有一个问题。尽管项目被配置为输出 LIB，但它们不是静态的 - 它们是动态的。您需要在 VC 项目中将其更新为静态（/MT 或 /MTd）。
之后，如果您想与 LIBCURL 静态链接，您需要以下内容：
截至目前（7.76.1 - 2021 年 4 月 14 日），这将在最新的 CURL 上 100% 有效，并且您将能够静态链接到您的项目中。
享受。
