Question

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。

有任何已知的解决方法吗？是否容易恢复到已知的工作版本？我不经常编译这个并且对它很不熟悉。

这是编译器错误：

好的，看起来两个文件中的typedef签名完全相同，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才能保持与最新mingw代码的兼容性。

当前版本的mingw64是否与SDL库不兼容？编译器错误，之前没有任何错误
