unresolved external symbol _WinMain@16

Question

I tried compiling the following code (From Ogre3d Beginner's Guide By Felix Kerger book)

#include "Ogre\ExampleApplication.h"    

class Example1 : public ExampleApplication
{
public:
void createScene()
{Ogre::Entity* ent =
mSceneMgr->createEntity("MyEntity","Sinbad.mesh");
mSceneMgr->getRootSceneNode()->attachObject(ent);
}
};



int main (void)
{
Example1 app;
app.go();
return 0;
}

So the compiled Process didn't work. I am currently using Visual Studio 2010 and OgreSDK_vc10_v1-7-3.

The errors are

1>InitializeBuildStatus:
1>  Touching "obj\Debug\OgreApp3.unsuccessfulbuild".

Replace the signature of your main function to the following:

INT WINAPI WinMain( HINSTANCE hInst, HINSTANCE, LPSTR strCmdLine, INT )

right bottom on your project

->property linker->subsystem

change your subsystem with "CONSOLE(/SUBSYSTEM:CONSOLE)"

Your compiler thinks the program is a windows application but your source code is for a command line application.
