I’m trying to use the glog logging library (LINK).
In VS2012 (I’m on Windows 8 Professional 64-bit (Japanese)), I create an empty solution with a single main.cpp file like the one in the documentation (LINK).
Also I import the glog project inside the solution (either the dll one or the static library one) and set the project dependency.
To avoid some errors I have to comment out line 97 from port.h:

/* In windows-land, hash<> is called hash_compare<> (from xhash.h) */
#define hash  hash_compare

While glog compiles, the main application gives me unresolved external symbol erros (with both dll and static version).

1>main.obj : error LNK2019: 未解決の外部シンボル "void __cdecl google::InitGoogleLogging(char const *)" (?InitGoogleLogging@google@@YAXPBD@Z) が関数 _main で参照されました。

1>main.obj : error LNK2019: 未解決の外部シンボル "public: __thiscall google::LogMessage::~LogMessage(void)" (??1LogMessage@google@@QAE@XZ) が関数 _main で参照されました。

I’m compiling as Win32.
If I check the debug folder it actually contains the dll+lib or static lib file.
I also tried linking to the library manually without using the visual studio dependency system, but it’s the same.

    I’ve built glog for MSVS2012 from trunk (little patch mentioned in header already presented here, as i know), so it works for me.
    Looks like your dependency description of glog library is missing.

    Can you add windows-specific

    #pragma comment(lib, "path_to_glog_from_project_dir.lib")

    to one of your project files, for example, directly into main.cpp and test it.
