错误 LNK2019:函数 ___tmainCRTStartup 中引用了未解析的外部符号 _main，但这一次不是 Windows/控制台问题！ [英] error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartup, but this time it's NOT a Windows/Console problem!

问题描述

所以，臭名昭著的错误又回来了.该项目抱怨它找不到 main() 方法(这就是错误的含义，对).

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).

但是我确实有一个主项目，而且我的项目应该是一个控制台项目.它以前有效，所以我知道不是那样.

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.

此外，该项目的类和文件太多，我无法将它们全部发布，因此我会根据您的要求发布任何您需要的类.

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.

这是 Visual Studio 2010 上的 C++、OpenGL 和 SDL 游戏.这不是任何库的问题，因为它在突然莫名其妙地显示此链接器错误之前运行良好.

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.

main() 方法:

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;
}

推荐答案

SDL_main.h 自动包含在 SDL.h 中，因此您总是会遇到讨厌的 #define.

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

随便写:

#include <SDL.h>
#undef main

它应该可以正常工作
