QApplication: no such file or directory

Any idea what is wrong? (Okay the tutorial is for Qt4 and I have Qt3, but does it make a difference for a "Hello World" program?).

Apparently there is a big difference even in a "Hello world" program .
I mean I also tried to start learning Qt4.0 using the famous official Qt book, C++ GUI Programming with Qt 3 (ISBN 0-13-124072-2), but from the first program in the book (hello world) i received compilation errors. The book is still great because besides the program examples (which i am sure can be easily modified to work in 4.0 also) it gives you great explanation of all related Qt concepts (slots, signals, etc...).

I am also a newbie to Qt and for now I sticked with the great Qt documentation (assistant) and so far so good. Actually not very far but still good )

I started by getting missing file errors and such like.

If you are using Linux and these commands are available on your
machine you can try:

apt-cache search qt

then, for all the stuff which sounds related to what you want, you do
apt-get install <name of the application>

You have to be root and to have write permission in /usr

PS If you have a Debian Sarge you will still miss one file, with an
unpronouncable name. I've forgotten which one it was, if you have a Debian
Sarge I'll send you the file if you want. Just reming me of its name
