Cpp file containing WinMain not being compiled

I've a file called AquaMain.cpp

#include "AquaGame.h"

using namespace Aqua;

#ifdef _WIN32

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
{
     AquaGame::get()->init();

     return AquaGame::get()->run();
}

#endif

This file is inside a static lib.

When I try to compile a project that uses this static lib the build fails with this error

1>MSVCRTD.lib(crtexew.obj) : error LNK2019: unresolved external symbol WinMain@16 referenced in function __tmainCRTStartup

The file AquaMain.cpp is not being compiled I don't know why...

If I move the WinMain function to the executable project the function is compiled and everything works, but I would like WinMain to be in the static lib.

Any ideas?

Even though AquaMain.cpp had the extension .cpp Visual Studio 2012 has using it as a header because AquaMain.cpp Property Pages had the "Item Type" field set to C/C++ header.

Changing the field to C/C++ compiler fixed the error.

you need to declare your WinMain as extern "C"

extern "C" int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
{
     AquaGame::get()->init();

     return AquaGame::get()->run();
}
