Visual Studio 2010 C++ /w Google Protocol Buffers. Cannot find 60 externals. Cannot compile

Question

I followed the instructions to the best of my ability. downloaded GPBuffers 5.0rc1 put the src/google folder into my project directory. Added the path to Settings > C/C++ > "Additional Include Directories".

But I think I need to place a -lprotobuf compiler option somewhere. I tried adding this to the C/C++ and Linker in the Settings > xxx > Additional Command Line Parameters.

But no luck.

It seems the libprotobuf.lib, libprotobuf-lite.lib and libprotoc.lib are missing. Perhaps it did not build correctly..

I have my serverThread.cpp which looks like:

#include "serverThread.h"
#include "sendStruct.h"

#include <fstream>
#include <string>
#include "messages.pb.h"

The log is reproduced below.

It seems its missing a reference to some library. As most of the dependencies are there.

Answer 1

Needed to compile Protobuf correctly. There is a vsprojects folder. Just build ONLY the libprotobuf and add the libprotobuf.lib as reference to the project by going to:

Properties > Linker > Input : Additional Dependencies > Edit...

If you copied it to your project folder/google put in google/libprotobuf.lib

Everything should compile smoothly now.

Answer 2

If you are building protobufs as a DLL then you will also need to define PROTOBUF_USE_DLLS in your client application to get it to pull in the DLL import __declspec stuff properly.

See https://code.google.com/p/protobuf/issues/detail?id=308#c9 for details.
