libqt-mt.so.3 not found with qt 4.2.2 installed


There have been multiple threads on this but none helped me...

Whenever I try to run ark, kedit, qtparted, or many other programs I get a message,

error while loading shared libraries: libqt-mt.so.3: cannot open shared object file: No such file or directory

I have qt 4.2.2 installed, built by me, using
Code:
./configure -mt -qt3support --prefix=/usr
make
make install
as root. It didn't work using a prebuilt package either...

My system: Slax (Avalanche OS) with xfce4.3.99beta

I tried ldconfig, it still does not work, this is especially aggravating because qt4 is supposed to be backwards compatible with qt3 apps!

Please help me!

The Mallegonian

first i havn't worked with qt4 yet but
the configure switch for threading with qt3 used to be -thread
when you conpile qt your self you have to make some of the symbolic links as needed to the library

There is no libqt*mt* anywhere with qt4

I tried -thread but it said that it was not recognised

Thanks,
The Mallegonian

The Qt 4 series is not binary compatible with the 3 series.
Qt 4 is also not completely source compatible with 3.
