It said there's something wrong with the header file, mmsystem.h, i can't use PlaySound()

#include <iostream>
#include <stdlib.h>
#include <mmsystem.h>
#include <string>
#include <windows.h>
#pragma comment (lib, "winmm.lib")

using namespace std;

int main() {
    PlaySound(TEXT("Happy Birthday To You.wav"), NULL, SND_SYNC);
    system("pause");
    return 0;
}

C:\Program Files (x86)\CodeBlocks\MinGW\include\mmsystem.h|905|error: 'DWORD' does not name a type|

C:\Program Files (x86)\CodeBlocks\MinGW\include\mmsystem.h|906|error: 'UINT' does not name a type|

C:\Program Files (x86)\CodeBlocks\MinGW\include\mmsystem.h|907|error: typedef 'UINT' is initialized (use decltype instead)|

It just came up tons of the errors in the header file like these, I linked to -lwinmm and checked the library, it still pops up.

PS I am using code blocks.

Solution

  • You need to include windows.h before mmsystem.h. windows.h should be first in your includes. mmsystem.h uses types defined in windows.h (including DWORD and UINT).
