尽管启用了 AutoLink (vcpkg)，但 VisualStudio for grpc 中仍然存在链接器错误

Question

我运行按照

中的建议

vcpkg install grpc:x64-windows
vcpkg install protobuf protobuf:x64-windows
vcpkg install protobuf[zlib] protobuf[zlib]:x64-windows
vcpkg integrate install

因此，这些软件包现在已安装在我的计算机上：

这是我的代码：

#include <grpcpp/grpcpp.h>

using grpc::ServerBuilder;

int main(int argc, char** argv) {
    ServerBuilder builder;
    return 0;
}

我没有在属性中配置任何路径（例如附加依赖项），因为我正在使用 vcpkg（我想这就是使用 vcpkg 的意义所在）。这是 vcpkg:

由于 27 个未解决的外部问题，我的项目无法在 Visul Studio 2019 中构建...

我在调试和 x64 配置中构建。

我错过了什么？我以为 vcpkg 会让生活更轻松？

Answer 1

It seems to be a problem of the grpc package.

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，问题就消失了。

也可以这样修复（我截图自Unresolved external symbol LNK2019）：

尽管启用了 AutoLink (vcpkg)，但 VisualStudio for grpc 中仍然存在链接器错误
