      I've searched the forums for this problem but none quite matched what's happening to me. I keep getting these error codes and my compile output is:
      @ld: warning: directory '/usr/local/pgsql/lib' following -L not found
      ld: warning: directory '/tmp/qt-stuff-85167/source/qt-everywhere-opensource-src-4.8.1/Desktop/Qt/4.8.1/gcc/lib' following -L not found

      Error while building project Gameattempt4-5 (target: Desktop)

      I'm running Mac osx 10.6.8 and when I try to delete the Q_OBJECT like almost every post says to do I get a different error.
      If I need to give anymore information just tell me.

        Have you tried the most simple solution: Clean All -> Run qmake -> Rebuild?

          Multiple times. That was the first thing I tried.

            Show us the code for that class, or if you can't post code describe what are you trying to do, or better try to replicate the behavior in a small test project that you can post here, if you don't find the problem when coding the test code.

              It's supposed to be a basic text based game.
              These are the two files I think are the problem.
              @#include "userclass.h"
              #include "ui_userclass.h"
              #include <QtGui/QApplication>
              #include <QtGui/QPushButton>
              #include <QtGui/QMessageBox>
              #include <QWidget>

              userclass::userclass(QWidget *parent) :
              QWidget(parent),
              ui(new Ui::userclass)
              {
              ui->setupUi(this);
              }

              userclass::~userclass()
              {
              delete ui;
              }
              void userclass::on_Fighter_clicked()
              {
              QMessageBox *choice=new QMessageBox;
              choice->setText("You chose the Fighter class");
              choice->show();
              this->close();
              }

              void userclass::on_Mage_clicked()
              {
              QMessageBox *choice=new QMessageBox;
              choice->setText("You chose the Mage class");
              choice->show();
              this->close();
              }

              void userclass::on_Knight_clicked()
              {
              QMessageBox *choice=new QMessageBox;
              choice->setText("You chose the Knight class");
              choice->show();
              this->close();
              }
              @
              @#include "mainwindow.h"
              #include "ui_mainwindow.h"
              #include "userclass.h"
              #include <QtGui/QApplication>
              #include <QtGui/QPushButton>
              #include <QtGui/QMessageBox>
              #include <QWidget>

              MainWindow::MainWindow(QWidget *parent) :
              QMainWindow(parent),
              ui(new Ui::MainWindow)
              {
              ui->setupUi(this);
              }

              MainWindow::~MainWindow()
              {
              delete ui;
              }
              void MainWindow::on_pushButton_2_clicked()
              {
              QMessageBox *choice=new QMessageBox;
              choice->setText("You chose to end the game");
              choice->show();
              close();
              }

              void MainWindow::on_pushButton_clicked()
              {
              QMessageBox *choice=new QMessageBox;
              choice->setText("You chose to attack");
              choice->show();
              userclass user;
              user.show();
              this->close();
              }

              void MainWindow::on_actionQuit_triggered()
              {
              this->close();
              }
              @

                I deleted an unnecessary line and the code started working again. Problem solved.
