Object file size increases in windows! why?

[Gobi Sakthivel]

My sample.h is

#include <string>
namespace xxx
{
      class abc
      {
           std::string m_name;

           public:
              void initialize();
      };
};

My Sample.cpp is

#include <sample.h>
using namespace xxx;

void abc::initialize()
{
    m_name = "Siva";
}

My Question is when i compile this code in Linux platform Using g++ compiler My sample.o's Size is 1Kb.. But when the same code is compiled in Windows platform using VC++ Compiler , My sample.o's size is 42Kb..Can some of the experts can help me on this, to reduce the size in windows... Is there any proble with '#include <string>' in Windows platform.

What were your VC++ project settings? Release build? Optimize on or off? CLR support yes or no? Unicode yes or no? C or C++?
Favor size over speed?

etc...

Release Mode , Maximum optimization O2, No CLR Support, No Unicode , and It is C++ code.

Flags used while compiling /c /W0 /O2 /GX /GR /DVER_7 /D "NDEBUG" /D "_WIN32_"

You should be using the /Os switch to favor small code. /O2 maximixes speed which can cause Visual C++ to create inline functions out of functins that don't have the inline qualiier. That will cause bloat.
