Difficulty using Protobuf 3.2 in C++ - c++

Question

I'm trying to use Protobuf in C++, but having trouble getting it to do anything meaningful. I'm using Visual Studio 2015.
I built the protobuf library. I'm using the latest version from github.
I have created a .proto file as such:
syntax = "proto3";
package Networking;
message Robot{
message KinematicLinkProto {
string name = 1;
float x_pos = 2;
float y_pos = 3;
float z_pos = 4;
float roll = 5;
float pitch = 6;
float yaw = 7;
float x_scale = 8;
float y_scale = 9;
float z_scale = 10;
}
repeated KinematicLinkProto links = 1;
}
I compile this, and try to add it to a project:
#include "Robot.pb.h"
int main(int argc, char **argv)
{
Networking::Robot robot_message;
return 0;
}
My linker links libprotobuf.lib. I am building it as /MD and libprotobuf is built as /MD.
For some reason, this simple program has the following two linker errors:
Error LNK2019 unresolved external symbol "private: static bool google::protobuf::io::CodedOutputStream::default_serialization_deterministic_" (?default_serialization_deterministic_#CodedOutputStream#io#protobuf#google##0_NA) referenced in function "public: virtual unsigned char * __cdecl Networking::Robot::SerializeWithCachedSizesToArray(unsigned char *)const " (?SerializeWithCachedSizesToArray#Robot#Networking##UEBAPEAEPEAE#Z)
Error LNK2019 unresolved external symbol "class google::protobuf::internal::ExplicitlyConstructed<class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > > google::protobuf::internal::fixed_address_empty_string" (?fixed_address_empty_string#internal#protobuf#google##3V?$ExplicitlyConstructed#V?$basic_string#DU?$char_traits#D#std##V?$allocator#D#2##std###123#A) referenced in function "protected: void __cdecl google::protobuf::internal::RepeatedPtrFieldBase::Clear<class google::protobuf::RepeatedPtrField<class Networking::Robot_KinematicLinkProto>::TypeHandler>(void)" (??$Clear#VTypeHandler#?$RepeatedPtrField#VRobot_KinematicLinkProto#Networking###protobuf#google###RepeatedPtrFieldBase#internal#protobuf#google##IEAAXXZ)
I'm very confused - this is a very simple program. What could I possibly be doing wrong?
EDIT: A colleague compiled proto 3001000. This version does seem to work. I'm curious as to what about 3002000 breaks everything.

If you are using DLL, use
#define PROTOBUF_USE_DLLS
