C++ PlaySound() Error

Question

I would like to make a question as far as an application regarding music manipulation is concerned: I compile a program with the function PlaySound() but the following message shows up: [Linker error] undefined reference to `PlaySoundA@12'. I use Dev c++ to do that, because I have a problem with the visual studio and I can not sign in to my Microsoft account and does not let me to use it. Well I dont't know what is going wrong and does not let me play the sound. I include the windows.h and mmsystem.h headers and all are properly written. Can anyone help me with that?

#include <windows.h>
#include <mmsystem.h>

int main(){
    PlaySound("test.wav", NULL, SND_FILENAME);
    return 0;
}

You need to link the compiler to the winmm.lib library for this to properly link.

I must use pragma once to do that? – Anastassis Kapetanakis May 06 '16 at 20:15
No. What does `pragma once` have to do with libraries? Where did you hear that idea? – Lightness Races in Orbit May 21 '16 at 14:31

Just add the following line before the main function.

#pragma comment(lib, "Winmm.lib")
