:-1: error: symbol(s) not found for architecture x86_64

nicky j

Hey n00b question.
I know there have been several posts about this, but none of the suggestions I find help.

Whenever I declare a slot in my .h file and define it in my .cpp file, it says that the 'symbols not found for x86_64'. However when I comment out the slot declaration and definition, my program compiles fine. I really want to have these slots, so how can I declare/define them and have them work?

here is my code:
browser_v1.pro:
@QT += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += webkitwidgets

TARGET = browser_v1
TEMPLATE = app

SOURCES += main.cpp
mainwindow.cpp

HEADERS += mainwindow.h

FORMS +=

CONFIG += x86_64
@

mainwindow.h:
@#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include <QWebView>
#include <QLineEdit>
#include <QToolBar>
#include <QGridLayout>

namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow
{
Q_OBJECT

public:
MainWindow(const QUrl& url);
void changeURLbarText();

private slots:
void changeURLbarText();
void makeSearchURL();
void makeSearch();

private:
Ui::MainWindow *ui;

QWebView *webview;
QLineEdit *URLbar;
QLineEdit *SearchBar;
QToolBar *NavBar;
QGridLayout *mainLayout;

};

#endif // MAINWINDOW_H
@

mainwindow.cpp:
@#include "mainwindow.h"

MainWindow::MainWindow(const QUrl& Url)
{

webview = new QWebView(this);
webview->load(Url);
connect(webview, SIGNAL(loadFinished(bool)), SLOT(changeURLbarText()));

URLbar = new QLineEdit(this);
connect(URLbar, SIGNAL(returnPressed()), SLOT(makeSearchURL()));

SearchBar = new QLineEdit(this);
connect(SearchBar, SIGNAL(returnPressed()), SLOT(makeSearch()));

QToolBar *NavBar = addToolBar(tr("Navigation"));
NavBar->addAction(webview->pageAction(QWebPage::Back));
NavBar->addAction(webview->pageAction(QWebPage::Forward));
NavBar->addAction(webview->pageAction(QWebPage::Reload));
NavBar->addAction(webview->pageAction(QWebPage::Stop));
NavBar->addWidget(URLbar);
NavBar->addWidget(SearchBar);


setCentralWidget(webview);
setUnifiedTitleAndToolBarOnMac(true);

}

void MainWindow::changeURLbarText()
{
URLbar->setText(webview->Url().toString());
}

@

main.cpp:
@#include "mainwindow.h"
#include <QApplication>

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QUrl Url;
Url = QUrl("http://www.google.com/ncr");
//MainWindow w;
//w.show();
MainWindow *browser = new MainWindow(Url);
browser->show();

return a.exec&#40;&#41;;

}

if it matters, I am using a Macbook Pro OS X 10.9 (64 bit), Qt 5.2

thanks in advanced for your help!

Ok so I can barely develop now because the program crashes before it can launch. I have tried making another program and I am having the same results. I am running using debug instead of release. There is nothing that I can find wrong with my code.

Is this a problem with running Qt on OS X? Or a problem with Qt 5.2. My Linux computer has never had this problem before.

Please help!
