configure qt thread issue (just compiled qt w/ -thread option)

Hi, I'm trying to run configure with kaudiocreator. I'm using RH 8.0. I'm got and error message like

checking for Qt... configure: error: Qt (>= Qt 3.2) (library qt-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!

So I went out and got the qt source code from trolltech version 3.3.2. I ran
#./configure -thread
#make
#make install
then i went back and tried configure with kaudiocreator again and am still getting the same error message. What did I do wrong? Thanks.

Make sure that you:

1. Have your qt install dir in your /etc/ld.so.conf
2. have QTDIR set
3. Have your qt library in your LD_LIBRARY_PATH

Did you un-install the qt rpm that came with deadrat?

Could you please elaborate a little on 2 and 3? Are these all in the /etc/ld.so.conf file?

rpm? deadrat? I don't understand.

Are you familiar with what PATH is?

DeadRat=RedHat
rpm = Redhat Package Manager.

Wild guess: RH came with some version of Qt,
you installed new version, but old version gets
picked up first.

Originally posted by Technoslave Are you familiar with what PATH is?

Which path? like the paths that I can set in my profile so i have access to them from anywhere in console? Which file are you referring to in 2 and 3?

Yes, what you describe as a PATH is what I'm talking about.

LD_LIBRARY_PATH and QTDIR are similiar in this regard...they just mean something different.

PATH is where you locate binaries.
LD_LIBRARY_PATH is where you locate libraries.
QTDIR is where you locate your QT Install.

Things like LD_LIBRARY_PATH and QTDIR usually only come in to effect when you're compiling things.

Here are some examples of things I have set in my .bashrc for the things I do.

PATH=/bin:/usr/bin:/sbin:/usr/X11R6/bin:/usr/local/bin:\
/usr/sbin:/usr/local/sbin:/home/scripts:/usr/local/mysql/bin:/usr/local/qt/bin:\
/usr/local/kde/bin:/usr/local/mrtg-2/bin:.

KDEDIR=/usr/local/kde
KDEDIRS=/usr/local/kde

QTDIR=/usr/local/qt-3.3.1

LD_LIBRARY_PATH=/usr/lib:/usr/local/lib:/usr/local/mysql4/lib:\
/usr/local/qt/lib:/usr/local/mysql4/lib/mysql:/usr/local/ssl/lib:/usr/X11/lib:\
/usr/local/kde/lib:/usr/local/lib/gaim

PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/X11R6/lib/pkgconfig

Once you determine that you have your pathes for things set correctly ( please don't use mine, above is nothing more than an example of how they can be set via your .bashrc ) trying recompiling and see what happens.

If you still don't understand, then I suggest that whatever you're attempting to do, find an RPM instead, until such a time as you've learned a little more.
