我也碰到的相同的原因...

            #pragma comment(lib, "Dbghelp.lib")
#pragma comment(lib, "libboost_filesystem-vc100-mt-s-1_49.lib")
加上以上两行,  只剩下 2个错误了. 如下
1>mongoclient.lib(log.obj) : error LNK2001: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::system_category(void)" (?system_category@system@boost@@YAAEBVerror_category@12@XZ)

1>C:\Users\zhufei\Desktop\MongodbFirst\x64\Release\MongodbFirst.exe : fatal error LNK1120: 2 unresolved externals
加上 #pragma comment(lib, "libboost_system-vc100-mt-s-1_49.lib") 并不能解决
补充:
C:\mongodb-src-r2.2.3\build\win32\64\release\client_build  
我链接的的确是以上目录下的 x64 release lib (scons --release --64 mongoclient.lib)
        

            
在工程中手动加上 error_code.cpp 就能解决上面的2个问题, 在mongodb源码解决方案中的simple_client_demo工程,它自己加上了  error_code.cpp 得到启发,解决了以上问题.
自己编译lib的问题是如此之多,  这里还不算版本冲突等问题, 所以建议大家用下面连接的方式
http://docs.mongodb.org/ecosystem/tutorial/download-and-compile-cpp-driver/
If you have a compatibility problem with the library, include mongo_client_lib.cpp in your project instead. For example:
在工程中加上 momngodb源码中的mongo_client_lib.cpp 就相当于加上了lib .
总值 开源的东西是给专家用的, 对我们只想熟悉 看看mongodb, 不想深入的人真叫一个恶心.
        

            mongodb有依赖库，boost里面的filesystem等···
