seems to work fine The error says that a warning was treated as an error. Therefore your problem is a warning message! Check them and fix these.
In case you don't know how to find them: Open the Error List (View > Error List) and click on Warning.

this one helps. remove DRIVER_INITIALIZE DriverEntry; Line Unreference registerObject using UNREFERENCED_PARAMETER register filter using FltRegisterFilter See the definition on msdn Use RtlInitUnicodeString DbgPrint("Driver Entry !!!!!");
The Process should be followed May be this is giving you error because of UNREFERENCED_PARAMETER has not been used.

hope this fix your issue I know that many questions have been asked with the similar title. I have a class like this: , I finally resolved the issue by disabling locally the warnings.

code :

#pragma warning (push)

#include <boost/thread.hpp>
#pragma warning(pop)

#pragma warning (push)
#pragma warning(disable: 4251)
    static boost::thread_specific_ptr< MemoryMgmt::MemoryManager> memory_manager_currentHA;
#pragma warning(pop)

I wish did fix the issue. The Visual Studio solution contains 13 C++ projects, and all of these probably have the "Treat warnings as errors" setting activated. Try disabling this options for all projects and compiling again.

This might help you In gcc-4.6 and above, you can use -Wno-error=cpp. In at least the clang released with Lion and later, you can use -Wno-error=#warnings. But since your build servers use an ancient gcc, you're probably out of luck there.
In general, pass -fdiagnostics-show-option to have warnings show output like:
