Hi Valeri,

Usually the installation of Qt is straight forward and I had never touch any
of these make files, you have to run the configure script first and the then
every thing will be done automatically. regarding your question if we
install Qt 3.0 over Qt 2.3 the answer is no, and usually I do not install it
in /usr/local. 

for compiling Qt 3.0 with STL, threads, ..etc. I usually use:

export QTDIR=/tools/qt3
export MANPATH=$QTDIR/doc/man:$MANPATH

export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH

export PATH=$QTDIR/bin:$PATH 

./configure -prefix $PWD -shared -debug -thread -qt-gif -stl -xrender -xft

anyway if you don't need the debug or threads or etc, just take them out
from the configure options.
and after it configure everything just call make.

after this you have to add the following to your environment:

export QTDIR=/tools/qt3
export QMAKESPEC=$QTDIR/mkspecs/linux-g++
export MANPATH=$QTDIR/doc/man:$MANPATH

export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH

export PATH=$QTDIR/bin:$PATH 

I hope this will help you.



regards 

Mohammad

Hello Mohammad

 The reason of my question is very simple. 
 I have downloaded Qt v.3. free edition I found I can not install it ulness
I hack
a couple of Qt MAkefiles. This is waht I was surprised with. I saw noi such
problem in past
(v.2.3). Did I miss something. Are you installing  Qt into /usr/local
directly

  Did you install Qt 3 over Qt 2 ?
