I have openSUSE 10.2 on x86_64 and I am struggling to get a KDE windeco to install.

I'm looking at this windeco:
http://www.kde-look.org/content/show...?content=48318

But when I configure I get this:

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!

I know I have QT installed (v3 and v4).

This happens a lot with KDE windeco and styles. Any way around it?

"checking for Qt... configure: error: Qt (>= Qt 3.2) (library qt-mt) not found. Please check your installation!

"I know I have QT installed (v3 and v4)."



It has been a long time since this question has been asked. We
used to get it a lot on Qt 3.1. The solution was to compile Qt with ./configure -thread

Since you have both v3 and v4 installed did you compile v3 yourself? If so check to see if you configured thread support in the compile.

No, I did not compile qt3 or qt4 myself. Yast shows that I have the rpms and devel packages for both, however.

I tried passing --disable-threading to the configure script but then it says it cannot find qt (instead of qt-mt).

I'm a bit lost...

the old configure standby --prefix=`kde-config --prefix` may be pointing to qt4
you should set the --prefix= in the configure to point to the base prefix of your qt3 instalation.
also since you have two qt it might help to put
export PATH=/path/to/kde3/bin:$PATH
export PKG_CONFIG_PATH=/path/to/kde3/lib/pkgconfig:$PKG_CONFIG_PATH

Thanks for the replies, by the way.

The command 'whereis qt3' reports that my qt3 is installed to /usr/lib/qt3.

I tried the path adjustments you suggested and it didn't seem to help. I even passed the /usr/lib/qt3 to the configure script using the --with-qt-dir param. Same results. Says it can't find qt-mt. I tried --disable-threading in addition to the --with-qt-dir param. Same results.

The thing is, I get this problem with a lot of the win-deco and styles I try installing. I could see it being a configure bug if it were specific to just one, but it's many of them.

Lipstik won't install either. Same results.

On the flip side, some work just fine (polyester, qtcurve, etc). It's odd.

Okay.... here's an update...

I use this configure command:
./configure --prefix='/opt/kde3/' --with-qt-libraries='/usr/lib/qt3/lib64/'

It gets me past the qt-mt error, but now it says:

checking for KDE... configure: error:
in the prefix, you've chosen, are no KDE libraries installed. This will fail.
So, check this please and use another prefix!

/opt/kde3 is correct. kde-config --prefix reports it as such, and I can see the directory.

Ideas?

You need to install the devel package for kdelibs.

I already have all the KDE devel packages installed. This includes kdelibs.

Update: I got this to work.

This is the configure command I had to use. It worked like a charm.

./configure --prefix='/opt/kde3' --libdir='/opt/kde3/lib64' --with-qt-libraries='/usr/lib/qt3/lib64'

Thanks for the help!
