QT3 application is not running on ARM Board

[yogeshgokul]

I am using vga not a small screen

Thats cool.

and i have used qDebug message in main.cpp
and i am getting that message in the console.

Thats a good news.

I have used many forms in my application and i am checking each form individually and i let u know shortly

Hello,

I am checking my application part by part.

I am doing something like this

case Key_Enter: // Mapped with Enter Key
{

qDebug( "Key Press Event: Enter" );
enterpushButton->setFocus();
if ( TRUE == XSet )
{
XSet = FALSE;
input = xlineEdit->text().toDouble();

if ( input >= 0 && input < 99999.999){
XVal = ((input * 1000) / (1000));
qDebug ( "XVal : %5.3lf",XVal);
xlineEdit->setText(QString::number( XVal, 'f', decimals_mm ) );
}

else if(input > 9999.999){
xlineEdit->setText(" OVERFLOW ");
}
else if(input < 0 && input >= -99999.999){
xlineEdit->setMaxLength(10);
XVal = ((input * 1000) / (1000));
qDebug ( "XVal : %5.3lf",XVal);
xlineEdit->setText(QString::number( XVal, 'f', decimals_mm ) );
}
else if(input > -99999.999){
xlineEdit->setText("OVERFLOW ");
}


}

}
This code works fine in the host .

But in the target when i press enter key if entered digits is more than 5 it should display "OVERFLOW" and it works fine in the target ..
But if entered digits is less than 5 it should display double value of what i entered but
gui hangs but i get the double value(qDebug) in the console .


I strace the same finally i got this,

write(2, "Key Press Event\n", 16Key Press Event
) = 16
write(2, "Key Press Event: Enter\n", 23Key Press Event: Enter
) = 23
ioctl(4, FIONREAD, [0]) = 0

ioctl(4, FIONREAD, [1]) = 0
write(2, "XVal : 789.000\n", 15XVal : 789.000
) = 15

Hi,


I added the macro -DQT_QLOCALE_USES_FCVT while compiling ,

./configure -embedded arm -shared -no-cups -DQT_QLOCALE_USES_FCVT

Now it works fine in the target.

Thanks for the support
