mingw64的当前版本是否与SDL库不兼容？以前没有任何编译器错误

Question

我认为最近对mingw64的更新打破了与SDL库的兼容性，但我不确定。

是否有任何已知的解决方法？是否容易恢复到已知的工作版本？我不经常编译它，而且对它很不熟悉。

这里的编译器错误：

好了，它看起来像两个文件中的typedef签名是完全一样的，所以只要你注释掉的代码：

typedef struct 
{ 
    WORD wButtons; 
    BYTE bLeftTrigger; 
    BYTE bRightTrigger; 
    SHORT sThumbLX; 
    SHORT sThumbLY; 
    SHORT sThumbRX; 
    SHORT sThumbRY; 
    DWORD dwPaddingReserved; 
} XINPUT_GAMEPAD_EX; 

typedef struct 
{ 
    DWORD dwPacketNumber; 
    XINPUT_GAMEPAD_EX Gamepad; 
} XINPUT_STATE_EX; 

在无论是“xinput.h”还是“SDL_dxjoystick_c.h”，它都将允许代码进行编译。

这显然只是一种临时措施，我认为SDL库代码可能需要更新以保持与最新mingw代码的兼容性。
