compiling Qt with thread support?

I had this error while i tried to install kmess and kopete...

" checking for Qt... configure: error: Qt (>= Qt 3.1 (20021021)) (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!"

What does the above error message mean?
What must i do?

please advise....

Thank you

it means that configure can't find your qt libraries. make sure you have qt version 3.1 or greater installed. If so, make sure you have the location in your path. If you still have problems, you can specify the location of the qt libs when you run ./configure. I forget the context, but it should be fairly easy to find.

how can you check if you have qt installed ?

Use Kpackage, or whatever package manager redhat uses. You might want to look at man rpm to see how you can do it from the console.

You might also want to check out rpmfind.net to see if the package you are trying to compile is already available as a rpm binary.
