How about consulting the readme files which come with the package you downloaded, or perhaps the message boards / FAQs from where you downloaded it.

i did read the readme file of installation but i dont understain the next part:


================================================== ========
2. Set some environment variables in the file .profile (or .login,
depending on your shell) in your home directory. Create the
file if it is not there already.

QTDIR - the directory in which you're building Qt
PATH - to locate the moc program and other Qt tools
MANPATH - to access the Qt man pages
LD_LIBRARY_PATH - for the shared Qt library

Note that under IRIX the additional LD_LIBRARYN32_PATH and
LD_LIBRARY64_PATH variables are used for specifying library
search paths. Set the variable that matches your configuration, or
see the rld(5) man page for more information.

This is done like this:

In .profile (if your shell is bash, ksh, zsh or sh), add the
following lines:

QTDIR=/usr/local/qt
PATH=$QTDIR/bin:$PATH
MANPATH=$QTDIR/doc/man:$MANPATH
LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH

export QTDIR PATH MANPATH LD_LIBRARY_PATH

In .login (in case your shell is csh or tcsh), add the following lines:

setenv QTDIR /usr/local/qt
setenv PATH $QTDIR/bin:$PATH
setenv MANPATH $QTDIR/doc/man:$MANPATH
setenv LD_LIBRARY_PATH $QTDIR/lib:$LD_LIBRARY_PATH

After you have done this, you will need to login again, or
re-source the profile before continuing, so that at least $QTDIR
and $PATH are set. Without these the installation will halt with an error
message.


On AIX set LIBPATH and on HP-UX set SHLIB_PATH instead of LD_LIBRARY_PATH.

Note that the SGI MIPSpro o32 and Sun WorkShop 5.0 targets are no
longer supported as of Qt 3.3.

================================================== =====

where is the .profile or .login , what to do with them?

> where is the .profile or .login
On your linux box.
But you're using windows, so I guess you need something else.
Like my suggestion of finding another board which is more QT-centric than this one.

does anybody knows a board about qt?

Qt for Windows is a commercial product (ie. not free). You can either develop for nix, use another toolkit, buy Qt for Windows or develop with this out-of-date version of Qt for Windows.
