I compiled protobuf with nmake in my win7 machine, using VS 12.0 tool chain and nmake check show the result pass all the tests. I compiled with -Dprotobuf_BUILD_SHARED_LIBS=ON. Everything seems fine, while, when I use libprotobuf.lib and libprotobuf.dll in my own project (configured with Release Win32 platform), it just prompt linking errors, I have added #define PROTOBUF_USE_DLLS in code. I have really been working on this issue for long time, still have no clues. Any message is really appreciate, thanks!
