First of all, this is a problem with the package-management of ubuntu, not
qt.
What you can do:
first do a
apt-get update
to get the latest possible packages for your system. And the search for qt
by doing
apt-cache search qt
and have a look at the packages, which are provided in the output.
If no qt-package is provided search the internet for ubuntu and qt. I do
not know, if there is a webpage like packages.debian.org for ubuntu. But I
guess it is a good point to start at www.ubuntu.org.
Maybe you have to add another source to your /etc/sources.list (iirc)
after that do a
apt-get update
apt-cache search qt
and then add the given package to your
apt-get install - command.
hth!

Then you need to switch to a newer ubuntu release or add some other
repository. To find more information look at the ubuntu websites and if
that doesn't help find an ubuntu forum where you can ask how to get qt4.

Hi once again!
Another thing, you can do is installing Qt4 from scratch by compiling
everything on your own.
Go to www.trolltech.com
get the latest qt 4.x open-source - sources
unpack it
cd into the new directory and try
./configure && make
then if everything went well, switch to user root and perform a make
install
If everything went well, you will have a new directory in /usr/local/
If you need to compile, you have to use qmake with the absolute path, which
will reside in something like
/usr/local/Trolltech/Qt-4.x-opensource/bin/qmake (please have a look on
your own. Just writing this out of memory)
I suggest not to put this in your PATH-environment, to keep your kde and
other stuff working.
One thing to remind:
You have to care about updating this software by yourself, as apt does not
know anything about this qt-version!
hth!
Bye,
Sumpi

hi,
i am using ubuntu6.06 dapper(in fact, i don't know what's the meaning of
'dapper') and the kernel version is kernel-2.6.15.
i have tried to install qt4 from compiling source after install
build-essential, but failed too. though ./configure it successfully, i get
errors when try to make it.
now, i am downloading .deb files related qt4 from
http://packages.ubuntu.com/, and hope it works well.

Dapper Drake is simply the code name of 6.06.
For your information, I have installed the qt4 packages on Ubuntu 6.06
Dapper. They are in the "universe" repository, not in the "main"
repository. If apt cannot find these for you, then it would appear that
you do not have "universe" enabled. (I usually use Synaptic to manage
packages rather than calling apt directly.)
However, the Ubuntu supplied packages did not provide what I wanted, so
I removed them and built qt4 from source. This was successful.
I have since upgraded that machine to Ubuntu 6.10 Edgy, and again built
qt4 from source (version 4.2.1).
The fact that you have failed to install packages with apt implies that
the "universe" repository is not enabled in /etc/apt/sources.list
The fact that building qt from source failed implies that something is
missing from your build environment, but I cannot guess what as you have
not provided any error messages.
I hope this information helps you.

Stephen Jackson

This is the first time I hear of such a problem. What are you trying to
install exactly? How is Synaptic destroyed?

If I remember well 6.06 had the 4.1.x version that were severely broken by a
bug which prevented to select a directory in the file dialog. If your
application needs that, you must build qt4 by yourself (a breeze) or
upgrade to a newer version of ubuntu.

hi, all
thank you for all your favor from the bottom of my heart! installing qt4 is
really so difficult in ubuntu? be worried.
but now 'apt-get install libqt4-core libqt4-gui libqt4-dev libqt4-debug
libqt4-debug-dev' works well after i have modify the /etc/apt/source.list.

No. We are not worried :) What you have described are the obstacles each
beginner has to master, for example setting up his/her development
environment.
You might have to set the LD_LIBRARY_PATH.
No offense taken, but linker messages such as
/usr/bin/ld：can't find -lXext
should clearly tell you where to look for the solution. If this is
"difficult" for you then you should refer to the man pages of g++ where
and how it locates libraries (and header files) or consult google.
Also make sure that you have the *developer* packages for Ubuntu
installed (for example the Xext library developer packages; they are
*not* installed by default). Again, this is very basic stuff every
developer should be familiar with :)
Cheers, Oliver
