我错过了什么?我认为 vcpkg 会让生活更轻松吗?
解决方案
在 Windows 上为 VisualC++ 链接 gRPC 的已接受答案的第二部分 完全解决了我的问题.
我将 #pragma comment(lib, "Ws2_32.lib") 添加到我的 cpp 文件中，问题就解决了.
它也可以像这样修复(我从 Unresolved external符号 LNK2019):

I build in the Debug and x64 configuration.
What am I missing? I thought vcpkg shall make life easier?
解决方案
It seems to be a problem of the grpc package.
2nd part of the accepted answer of Linking gRPC on Windows for VisualC++ exactly fixed my problem.
I added #pragma comment(lib, "Ws2_32.lib") to my cpp-file and the problem was gone.
It also can be fixed like so (I've taken the screenshot from Unresolved external symbol LNK2019):
这篇关于尽管启用了 AutoLink (vcpkg)，但 VisualStudio for grpc 中的链接器仍然错误的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
