Allegro4/C++ giving error - c++

Question

I'm using the following code (Allegro 4, C++), and getting the following error:
#include <allegro.h>
//defines
#define MODE GFX_SAFE
#define WIDTH 640
#define HEIGHT 480
int main (void)
{
int ret;
int counter;
//initialize allegro
allegro_init();
install_keyboard();
install_timer();
srand(time(NULL));
//set up screen
//set video mode
ret = set_gfx_mode(MODE, WIDTH, HEIGHT, 0, 0);
if (ret != 0)
allegro_message(allegro_error);
allegro_exit();
return 0;
}
Error:
1>MSVCRTD.lib(crtexe.obj) : error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartup
All the previous answers regarding that error tell me to switch to "Console" from "Windows"; but I already have "Console" in Properties->Linker->System->Subsystem.
If you don't have an answer, I'd be happy with something I could do to help narrow down the problem: I've used Allegro with C, but I want to use C++ to take advantage of OOP, and so I still have a lot of work to do.
Update:
#include <iostream>
#include <allegro.h>
using namespace std;
int main ()
{
cout << "Hello World";
return 0;
}
doesn't work, but
#include <iostream>
using namespace std;
int main ()
{
cout << "Hello World";
return 0;
}
does.
Now what? Answer: Start with Empty project.
Update2: restarted with an empty project, same code. First block (alleg.lib in linker, but allegro.h not included) works, second code (allegro.h included) doesn't. However, the bug is different:
1>LINK : fatal error LNK1561: entry point must be defined
What now?
Edit^2:Ignore all the following: I forgot to go back to including Allegro. It works now. Thanks everyone for the answers.
Edit: Adding:
END_OF_MAIN()
or
int END_OF_MAIN()
give the error "fatal error C1004: unexpected end-of-file found"

Answer 1

You are getting the error because you are attempting to integrate allegro into a project that is non-empty.
You must create the project as an EMPTY PROJECT type:
New... > Project... > Visual C++ > Empty Project
--EDIT FOR SECOND ERROR--
You must append END_OF_MAIN() after the closing brace of int main():
int main() {
//...
}
END_OF_MAIN()
