Google gRPC (C++) building under VisualStudio 2013. Link errors

Question

I'm trying to setup gRPC for my project in Visual Studio. Did everything as described here: http://www.infopulse.com/blog/grpc-framework-by-google-tutorial/. (Trying to compile helloworld example -> Git grpc/examples/cpp/helloworld)

The main problem I'm getting, while compiling:

unresolved external symbol "void _cdecl grcp::FillMetadata
... and so on.

Nothing wrong with protobuf (Everything working) OpenSSL, zlib - OK.

My Includes:

• $(SolutionDir)..
• $(SolutionDir)..\include
• $(SolutionDir)..\third_party\protobuf\src
• $(SolutionDir)\packages\grpc.dependencies.zlib.1.2.8.10\build\native\include
• $(SolutionDir)\packages\grpc.dependencies.openssl.1.0.204.1\build\native\include
• $(SolutionDir)\packages\gflags.2.1.2.1\build\native\include
• $(SolutionDir)\packages\gtest.1.7.0.1\build\native\include

Additional dependencies:

• libprotobuf.lib
• grpc.lib
• gpr.lib
• libeay32MDd.lib
• ssleay32MDd.lib

Everything in correct folders.

What am I missing here? Maybe some of you have an already working .sln project with all dependencies list? I know that the problem must be connected to some .lib that I'm missing here.

It looks like you're not linking in the grpc++ code. It's unfortunately not a supported target right now, but we're looking to remedy that very soon. I'd really like to be offering a nuget package for C++ users.

If you want to try for now though, make sure you're compiling the vsprojects/vcxproj/grpc++/grpc++.vcxproj project alongside the rest of your code. Let us know how you go (and please file bugs at github.com/grpc/grpc/issues to help us prioritize things).
