Clearly you're not compiling Boost.Python. There is no such source file as ContainerOperation.cpp in that library.

Is there a way to integerate lambda into boost python.

OperatingSystemLib.mak works .. i just can't put lambda inside implementation file for boost.python.

I suggest that you're missing an #include somewhere, but it has little or nothing to do with Boost.Python.

Probably you need

#include "boost/lambda.hpp"

but I'm only guessing.
