Basic help please! ('QT' Gui compile problem)

[mike phillips]

I need help! I have searched back 5 pages too.

As a COMPLETE beginner (at an advanced age!!) in C programming, I downloaded and installed Dev-C++ 4.9.9.2 with mingw. On Win XP SP3 I am looking for a windows type GUI so I downloaded and installed QT 4.4.3. (with mngw). Dev-C++ in c:\dev-C++, QT in C:\qt and mingw in C:\mingw, using the Windows install package for QT qt-win-opensource-4.4.3-mingw.exe

I followed the web page http://sector.ynet.sk/qt4-tutorial/preparations.html on installing in Windows and set the path etc as per. The good old "Hello world compiles fine.

I successfully composed the 'test' QT prog at http://sector.ynet.sk/qt4-tutorial/my-first-qt-gui-application.html. I also downloaded the offered zip file of the same. My listing matched that of the zip. Here is the first part of the listing:

include <QtGui>

include "myqtapp.h"

// if we include <QtGui> there is no need to include every class used: <QString>, <QFileDialog>,...

myQtApp::myQtApp(QWidget *parent)
{
setupUi(this); // this sets up GUI

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

I then tried to compile in Dev. The compiler halts with a highlight at line 1 #include <QtGui>

Compile log (first bit, anyway): 502 errors!!!

Compiler: Default compiler
Executing g++.exe...
g++.exe "C:\Qt\4.4.3\bin\myqtapp.cpp" -o

I have tried fiddling with the directories/bin and other settings in Dev with no success. I do appear to have 2 sub folders on C now, called mingw32, one in dev-C and the other in mingw which puzzles me.

I should state that I am pretty ignorant regarding compilation and the 'old-fashioned' Dos system of make and qmake etc, so I would appeciate a considerate hand-holding or pointing to a help file or two.

Many thanks in anticipation.
