mingw64的當前版本是否與SDL庫不兼容？以前沒有任何編譯器錯誤

Question

我認爲最近對mingw64的更新打破了與SDL庫的兼容性，但我不確定。

是否有任何已知的解決方法？是否容易恢復到已知的工作版本？我不經常編譯它，而且對它很不熟悉。

這裏的編譯器錯誤：

好了，它看起來像兩個文件中的typedef簽名是完全一樣的，所以只要你註釋掉的代碼：

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; 

在無論是「xinput.h」還是「SDL_dxjoystick_c.h」，它都將允許代碼進行編譯。

這顯然只是一種臨時措施，我認爲SDL庫代碼可能需要更新以保持與最新mingw代碼的兼容性。
