#2 Can't compile

[Anonymous]

I run configure with the --prefix=/usr flag, but this
isn't my problem.
The script tells me that he can't find the qt
libraries. I have qt. I have compiled programs using
qt. The script simply tells me:

---output---
checking for Qt... configure: error: Qt (>= Qt 2.2.2)
(libraries) not found. Please check your installation!
For more details about this problem, look at the end of
config.log.
---end output---

So, I looked into config.log and I realized that it had
problems with QIconView.

QStringList *t = new QStringList();
QIconView iv(0);
iv.setWordWrapIconText(false);

s.setLatin1("Elvis is alive", 14);

return 0;
}

What am I doing wrong? I already told configure to look
the libraries of qt in a specified dir with
--with-qt-dir=/usr/local/qt or with
--with-qt-libraries=/usr/local/qt/lib .
