使用SDL库时的链接器错误:_main已在main.obj中定义 [英] Linker Error when using the SDL Library: _main already defined in main.obj

问题描述

所以我已经知道为什么会发生此错误，在SDL_main.h文件中创建了一个"main"宏，这将导致您实际的main函数出现问题.

So I already know why this error happens, inside the SDL_main.h file a 'main' macro is being created, which will cause problems with your actual main function.

只是所有明显的解决方法似乎都没有帮助我.我已经尝试过:

It's just that none of the obvious workarounds seem to be helping me. I have tried:

1. 使用(int argc，char * argv [])定义我的主要功能.

1. Defining my main function with (int argc, char* argv[]).

使用C链接对其进行了尝试，如SDL_main.h中的注释所示:

Tried it with C linkage like the comments in SDL_main.h suggest:

*  The application's main() function must be called with C linkage,
*  and should be declared like this:
*  \code
*  #ifdef __cplusplus
*  extern "C"
*  #endif
*  int main(int argc, char *argv[])
*  {
*  }
*  \endcode

尝试不确定主线.

Tried undefining main.

我还可以尝试使用其他技巧来使主功能再次正常工作吗?

Are there any other tricks I can try in order to get the main function working normally again?

推荐答案

也可以在main.cpp文件顶部尝试此操作:

Try also this at the top of your main.cpp file:

#define SDL_MAIN_HANDLED

这应该导致SDL跳过所有的main废话.

That is supposed to cause SDL to skip all of its main nonsense.

请注意，在包含SDL之前，需要先进行以下操作:

Note that it needs to happen before you include SDL:

#define SDL_MAIN_HANDLED
#include "SDL2/SDL.h"
