QT3 Problem

[dumb_terminal]

I am new to GUI programming, while surfing through trolltech i find this tutorial. I tried several ways but couln't make it run. can somebody help please ???
Here is the code :

/*
        A small program to demonstrate QT
        FileName : main.cpp
*/

#include <qapplication.h>
#include <qpushbutton.h>

int main(int argc, char *argv[])
{
        QApplication app(argc, argv) ; //application created

        QPushButton button1("hello world", 0) ; //button created params - caption, parent 0 for no parent
        button1.resize(100, 30) ; //resize params - width, height
        app.setMainWidget(&button1) ; //not necessary but every application should have a main widget
        button1.show() ; 
        return app.exec() ;
}

then i do the following
qmake -project
qmake
make
chmod +x main.o
./main.o

the out come is this : "bash: ./main.o: cannot execute binary file"

main.o is just one of the binary files that make up your executable - it is NOT in itself an executable. The actual executable is either named a.out, or simply main. If the make files did not result in an executable, then you need to link the .o files with the appropriate libraries, such as qt, and create one.

Thanx man. You r right. main.o is just a binary file. The thing that runs is another file named after me...! Now how weird is that ??? Do you have any explaination ???

qmake -project names the project with the name of the directory it is in. So I suppose you had this file and you were running qmake in your home directory, which was named after you so the project was named after you and therefore the program itself was named after you.

Of course it's kind of silly to have a program named "dumb_terminal"... ROFL

Thanx to you all for your help.

I am really new to linux programming (7 and a half days) so have to learn a lot.

Of course, there are times when I think about chaning my handle to "dim_bulb"...
