【问题描述】：

我认为最近对 mingw64 的更新破坏了与 SDL 库的兼容性，但我不确定。

是否有任何已知的解决方法？恢复到已知的工作版本是否容易？我不经常编译这个，对它很陌生。

这是编译器错误：

【解决方案1】：

好的，看起来两个文件中的typedef签名完全一样，所以只要你注释掉这段代码：

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“xinput.h”或“SDL_dxjoystick_c.h”中，它将允许代码编译。

这显然只是一个临时措施，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。
