Why always cant find qt library?

[xycheng97]

I installed qt-3.2.3 with mt support,
and configure konq-e with:
./configure --enable-qt-embedded --enable-embedded --disable-debug
--with-qt-dir=/root/qt/qt-embedded-free-3.2.1/
--with-qt-includes=/root/qt/qt-embedded-free-3.2.1/include/
--with-qt-libraries=/root/qt/qt-embedded-free-3.2.1/lib/ --without-ssl
--host=i686-linux --target=sh4-linux --disable-pcre

But it cant find the qt library. Can anybody help?
Below is the error message:

checking for Qt... configure: error: Qt (>= Qt 3.1 (20021021)) (library qte-mt)
not found. Please check your installation!
For more details about this problem, look at the end of config.log.
Make sure that you have compiled Qt with thread support!
