please help me

What you didn't mention is that you are building a project for Harmattan now (either on purpose or by accident) and your Harmattan SDK files just might be out of date. Install the latest Qt SDK and try again.

i remove all qdebug and a qml register file code ...and rebuild again this is work fine
but now i got face another problem is i wanna to read a .txt file bt failded my code is working good for symbian and desktop application.cud you plz tel me what is happening code is

void GraphicsEngine::loadPawnLocations(){
// bool isComment = false;
QString sToken;
int index;
int x_pos = 0;
int y_pos = 0;

QFile file("qml/Test2/pawnPosition.txt");

QStringList strings;

if (file.open(QIODevice::ReadOnly | QIODevice::Text))
{

QTextStream in(&file);
char tmp;
in>>index;
in>>tmp;
in>>x_pos;
in>>tmp;
in>>y_pos;
while (!in.atEnd() ) {

if (index >= PathMap::JOURNY_CELLS
&& index < PathMap::JOURNY_CELLS + PathMap::HOME_STREET_CELLS) {

pawnsInHomeStreet[index
- PathMap::JOURNY_CELLS][X_POS] = x_pos;
pawnsInHomeStreet[index
- PathMap::JOURNY_CELLS][Y_POS] = y_pos;

} /**
* locations for the pawns in castle
* */
else if (index
>= PathMap::JOURNY_CELLS + PathMap::HOME_STREET_CELLS) {
pawnsInCastleLocations[index - PathMap::JOURNY_CELLS
- PathMap::HOME_STREET_CELLS][X_POS] = x_pos;
pawnsInCastleLocations[index - PathMap::JOURNY_CELLS
- PathMap::HOME_STREET_CELLS][Y_POS] = y_pos;

} /**
* Normally traveling
* */
else {
pawnLocations[index][X_POS] = x_pos;
pawnLocations[index][Y_POS] = y_pos;
}
strings.clear();

in>>index;
in>>tmp;
in>>x_pos;
in>>tmp;
in>>y_pos;



}
}else
{
exit(1);
// qDebug()<<"file not open";
}
}

Could you tell what the code is doing? Given that the source code works elsewhere my best guess is that the file does not exist in the specified location on the affected device. What is the current working directory of the application?
