Error when Try to debug with Qt Simulator. (error: collect2: ld returned 1 exit stat)

Hello everyone,

Hope you all are fine,

I am facing a problem in debugging my project with Qt Simulator, when i debug, the following errors appears.

Running build steps for project my3rdMobielApp...
Configuration unchanged, skipping qmake step.

What should I do?

Thanks In advance

Guess what the error could be

undefined reference to `Dialog::addtext()'

Maybe addText()? how does your Dialog class look like?

#include "dialog.h"
#include "ui_dialog.h"

Dialog::Dialog(QWidget *parent) :
QDialog(parent),
ui(new Ui::Dialog)
{
ui->setupUi(this);
showprog();
connect(ui->pushButton,SIGNAL(clicked()),this,SLOT(addtext()));
}

void Dialog::showprog(){
info = new QSystemDeviceInfo(this);
ui->progressBar->setValue(info->batteryLevel());
connect(info,SIGNAL(batteryLevelChanged(int)),ui->progressBar,SLOT(addtext()));
}
void Dialog::addtext(){
ui->listWidget->addItem(ui->lineEdit->text());
}

Dialog::~Dialog()
{
delete ui;
}

its the Dialog class and at that time i forget to use addtext() function in Dialog.cpp. I've used it in Dialog.cpp but error is still there,,,,

its the Dialog class

Well, you need to include the corresponding header for QSystemDeviceInfo. Further you need to alter your pro file (if not already done) to include QtMobility and some features for your symbian device. See http://wiki.forum.nokia.com/index.ph...n_API_-_Part_1 for a start.
