Help needed
Message 1 in thread
Hi.
I have recently brought a book called C++ GUI programming with QT4, and I
can't get it to work. I have installed both QT4 and MinGW, but everytime I
try to compile the program, I get several compile errors, some about not
recognising <QApplication> and <QLabel>, others about 'parse errors' which
unfortunately I don't know about.
Any help on this matter would be much appreciated.
Apologies if this is the wrong mailing list.

¿Are you compiling via the QT console link? I mean, in
Programs -> Qt 4.x.x -> Qt console

Okay, this is a step by step "How-to get your book working":
- Look at the cover to make sure you've goot the right book
(look at the large letters)
- If the large letters appear upside town, turn the book by
180 degrees
- If you see a big grinning face, it might be that you are looking
at the back of the book (it's the author's face). Turn it
appropriatelly until you see the big friendly letters (the
book title) (*)
- Now open the first page. It is usually blank, but don't get
confused yet (sometimes though there appears a silly "I would
like to dedicate this book to..." sentence)
- After turning to the next page you will finally
arrive to what is called "table of content". This is an
advanced subject so we will skip it for now. Turn to the
next pages until you reach the foreword
- Read the foreword. If you still like the book go on reading. Else
bring back the book to where you've purchased it.
- Read the 1st chapter
- If you have not found what you were looking for, it might now
be the time to skip back to the "table of content" (see below).
- If you are adventurous though you might read on, until
you have reached the end of the book (sometimes it is marked
in capital letters with "THE END", so you won't accidentally
read past the end of the book, which would result in a "book
overflow"!)
- The "table of content": this is for advanced users (expert users
might also refer to the "appendix", but we'll leave this out for
now). Each "chapter" is identified by a title, together with a
number, the "page ID". Each page has a little number printed on
it (mostly on the bottom left/right of the pages).
- When you have found a "chapter" which you like, search the proper
page, given the page ID:
- Beginners should begin with a "linear search", starting with the
first page after the "table of content"
- Advanced users will prefer a "Binary search", starting
approximatelly in the middle of the book
- Expert users will use a "random search"
- When you have found the proper chapter, go on just like with the
1st chapter (but pay attention that you don't read the following
chapter accidentally, except if you are adventurous and would like
to read until the end of the book)
That's it! In a similar way you can almost enjoy any other book!
(*) There are several strategies turning a book to the right
orientation, but this is left as an exercise for the reader.

Don't worry - we are all nice people on this list and sometimes are very
happy to share our knowledge, also about off-topic issues ;)

p.s. Don't get offended! But today it's Friday, so I'm allowed to write
such a silly post ;)

This has got to be one of the funniest and possibly most accurate and
thorough post I've ever seen on the list!
Thanks Oliver for lightening my Friday!

At great risk of being flamed here.....
Marco,
The book CD installs Qt4 in /usr/local/Trolltech/Qt-4.1.1.
The Makefile are unfortunately looking for all the stuff to be
in /usr/local/Trolltech/Qt4.
You can use the -I directive with make:
make -I /usr/local/Trolltech/Qt-4.1.1
OR do as I did and simply
cp -r /usr/local/Trolltech/Qt-4.1.1 /usrlocal/Trolltech/Qt4.

I don't see why (appart from the misswriting that originated a very funny

Ah, I suposed (wrongly, I see) that Marco was trying to compile some code of
himself. I guess it's because I did that before I buyed the book :-)
Regards, and good luck Marco!

cp? symlink would suffice, no wasted disk space :)
ln -s /usr/local/Trolltech/Qt-4.1.1 /usrlocal/Trolltech/Qt4
Also, if you use project files and invoke the correct qmake directly,
it handles all the includes and such on its own:
/usr/local/Trolltech/Qt-4.1.1/bin/qmake && make
Also, you may need to add /usr/local/Trolltech/Qt-4.1.1/lib to
LD_LIBRARY_PATH (so the .so files can be found)

Hmm, he said he installed MinGW, so I guess the above does not applies to him,
as usually Qt installs itself in c:\Qt\4.1.1\> (perhaps it is possible to
install it that way using also MSys, I don't know)
