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
