Instaling QT 3.0.3 on a machine running knoppix

I installed knoppix to my hard drive, and for it works quite nicely on my machine. However, a lot of programs, and themes require QT 3.0.3 to run and I don't think that it comes as part of knoppix.

I've found a couple of files that seem to be QT 3.0.3 but whenever I install, them I still get the same error messages as before.

The error message is this.

"checking for Qt... configure: error: QT (>= QT 3.0.3) (headers and libraries) not found. Please check your installation!"

Do you think any of the packages on this page

would help?

If anyone has some advice or could offer me some help, that'd be great!

Oh, one last thing, Linux is completely new to me, but I haven't been doing too badly so far.

Before trying to compile yourself (which is something like ./configure; make; make install) you should try to find the applications you want as ready made Debian packages (Knoppix is Debian). You can use aptitude to find packages that are Knoppix stock or have a look at, there is a search page.

After a successful search on become root, put the line(s) beginning with "deb" into your /etc/apt/sources.list, do an "apt-get update" and "apt-get install <package_name>". This will implicitly install all packages that are required, e.g. libs.

If all this fails, you should think about compiling apps yourself. This is not so good, as the package management system doesn't know anything about these.

However, if you want or need to do so, here is the answer to your original question:
It looks like you need libqt3-dev to compile that specific application.

libqt3-dev and qt3-dev-tools conflict. Try removing the latter before installing libqt3-dev.

As the relevant tools are also in libqt3-dev (e.g. qmake) hopefully there should be no problems concerning further dependencies - but I'm no QT developer. So to be safe, take a close look at the output when deinstalling qt3-dev-tools.
