c++中的链接器错误

我对c++很陌生，我正在用一本书来学习计算机图形学。我使用的是Visaul Studio 2013和Windows 8。当我尝试重新构建解决方案时，我得到以下错误:

1   error LNK2001:unresolved external symbol "_wWinMain@16".    C:applicationgl_applicationgl_applicationMSVCRT.lib(wcrtexew.obj)   gl_application
2   error LNK1120: unresolved external symbol   C:applicationgl_applicationReleasegl_application.exe    1   1   gl_application

我从书中找到了下面的代码，所有的建议都没有帮助。

application.cpp

       #include <glut.h>
        #include "screen_interface.h"
        #include "global_definitions.h"
        #include "palette.h"

        void main_loop( void )
        {
           for( long x=0 ; x<256 ; x++ )
             for( long y=0 ; y<480 ; y++ )
                screen[ y * 640 + x ] = palette[ x ];
            glDrawPixels( x_res, y_res, GL_BGRA_EXT, GL_UNSIGNED_BYTE, screen );
            glFlush();
        }
        void initialise_world( void )
        {
          initialise_platform();
           display_func = 1;
        }
         void display( void )
        {
  switch( display_func )
  {
    case 0  : initialise_world();
              break;
    case 1  : main_loop();
              break;
    default : display_message();
  }
}
int main( int argc, char **argv )
{
  glutInit( &argc, argv );
  glutInitDisplayMode( GLUT_SINGLE | GLUT_RGBA );
  glutInitWindowSize( x_res, y_res );
  glutCreateWindow( "3D-Grafik Programmierung" );

  glMatrixMode( GL_PROJECTION );

帮助将是伟大的，因为我试图解决这个天了。我已经尝试将入口点设置为wWinMainCRTStartup，但没有帮助。
