Qt and FMOD simple playsound

Hey. I'm still kind of a newbie with this stuff. I got fmod to work with dev c++ just fine, but i'm having trouble with Qt. I just need to be able to play a .wav file and i'll be good to go. Here is the code i'm using so far. It runs fine but makes a beeping sound instead of the sound I want it to play.

Code:

---

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include "QPainter.h"
#include "inc/fmod.h"
#include "inc/fmod_dsp.h"
#include "inc/fmod_errors.h"
 
 
 
MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
}
 
MainWindow::~MainWindow()
{
    delete ui;
}
 
void ERRCHECK(FMOD_RESULT result)
{
    if (result != FMOD_OK)
    {
        printf("FMOD error! (%d) %s\n", result, FMOD_ErrorString(result));
        exit(-1);
    }
}
 
void MainWindow::paintEvent(QPaintEvent *)
{
    QPainter p(this);
    p.setPen(Qt::black);
    p.setBrush(Qt::black);
 
    FMOD_SYSTEM     *system;
    FMOD_SOUND      *snare1;
    FMOD_CHANNEL    *channel = 0;
    FMOD_RESULT     result;
 
    result = FMOD_System_Create(&system);
    ERRCHECK(result);
 
    result = FMOD_System_Init(system, 32, FMOD_INIT_NORMAL, NULL);
    ERRCHECK(result);
 
    result = FMOD_System_CreateSound(system, "drums/snare1.wav", FMOD_SOFTWARE, 0, &snare1);
    ERRCHECK(result);
 
    result = FMOD_System_PlaySound(system, FMOD_CHANNEL_FREE, snare1, 0, &channel);
    ERRCHECK(result);
 
 
}

i am using qt4.7 with fmod ex 4.38.03，but i got a serious problem to link fomd lib：

bool FmodAudio::initMusic()
{
//init
FMOD_RESULT result;
result = FMOD_System_Create(&mSystem);
ERRCHECK(result);

//test version
unsigned version = 0;
result = FMOD_System_GetVersion(mSystem,&version);
ERRCHECK(result);

if( version < FMOD_VERSION )
{
char sz[100];
sprintf(sz,"oldversion FMOD %08x.you need %08x\n",version,FMOD_VERSION);
QMessageBox().warning(NULL,"FMOD version error",QString(QLatin1String(sz)));
return false;
}

// init
result =FMOD_System_Init(mSystem,1,FMOD_INIT_NORMAL,0 );
ERRCHECK(result);

// create stream
result = FMOD_System_CreateStream(mSystem,"shot.wma",FMOD_H ARDWARE | FMOD_LOOP_NORMAL | FMOD_2D,0,&mSound );
ERRCHECK(result);
// play
result = FMOD_System_PlaySound(mSystem,FMOD_CHANNEL_FREE,mS ound,false,&mChannel );
ERRCHECK(result);

return true;
}

the error is：
undefined reference to `FMOD_System_Create@4'
undefined reference to `FMOD_System_GetVersion@8'
undefined reference to `FMOD_System_Init@16'
undefined reference to `FMOD_System_CreateStream@20'
undefined reference to `FMOD_System_PlaySound@20'

in the .pro file，i set to link fmod lib：
FMODHOME = E:\Qt\FMOD_Pro_API_Win32\api
INCLUDEPATH += $$FMODHOME\inc
LIBS += -L$$FMODHOME\lib\libfmodexL.a

how to resolve the problem，thanks all！！

i made a mistake that i write “target” attribute in the pro file。remove it then work ok
