What Linux distribution are you using? Do you have qt3-devel installed?

[R.M]

I use Debian ,,
Sorry but when I try to intall it like that apt-get install qt3-devel
, the resuslt is that :
Reading package lists... Done
Building dependency tree... Done
E: Couldn't find package qt3-devel

do I install it in wrong way

[daark.child]

On Debian based distros install libqt3-dev e.g.

aptitude update
aptitude install libqt3-dev
