c++ - error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartup, but this time it's NOT a Windows/Console problem!

Question

So, the infamous error is back. The project is complaining that it can't find the main() method (that's what the error means, right).

However I do have a main, and my project is a Console project, as it should be. It worked before, so I know it's not that.

Also, the project has too many classes and files for me to post them all, so I will post any classes you need by request.

It's a C++, OpenGL and SDL game on Visual Studio 2010. It's not a problem of any of the libraries, as it was working fine before it suddenly and inexplicably showed this linker error.

EDIT: The main() method:

int main(int argc, char **argv)
{
 glutInit(&argc, argv);
 glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH | GLUT_ALPHA);
 glutCreateWindow("Game");

 glEnable(GL_DEPTH_TEST);
 glEnable(GL_NORMALIZE);
 glEnable(GL_COLOR_MATERIAL);
 glEnable(GL_BLEND);
 glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);

 g = Game();
 glutInitWindowSize(g.getScreenWidth(), g.getScreenHeight());
 //glutPositionWindow(1280, 50);

 // Callbacks
 glutDisplayFunc(handleRedraw);
 glutReshapeFunc(handleResize);
 glutMouseFunc(handleMouseClicks);
 glutPassiveMotionFunc(handleMouseOvers);
 glutKeyboardFunc(handleKeyboardEvents);
 glutTimerFunc(50, moveItemToInventory, 0);

 glutMainLoop();

 return 0;
}

SDL_main.h is included automatically from SDL.h, so you always get the nasty #define.

Just write:

#include <SDL.h>
#undef main

And it should work fine
