Can't compile anything with qt3/qt4

Hello.

I can't compile anything with qt3 or qt4 on i686.
Packages depending on qt3 fail ./configure with (example kaffeine 0.8.6 pkgbuild from the repo)

checking for Qt... configure: error: Qt (>= Qt 3.3 and < 4.0) (headers and libraries) not found. Please check your installation!
For more details about this problem, look at the end of config.log.

Packages depending on qt4 fail ./configure with (example vlc-nightly pkgbuild from aur)

checking for QT4... configure: error: QT4 library not found

I don't use testing or unstable, other than that the system is up-to-date.
Any idea what the problem is?

Re: Can't compile anything with qt3/qt4

try
$  export QTDIR=/usr
before the configuration step.

Best,

Re: Can't compile anything with qt3/qt4

Are you sure qt and qt3 are installed proper?
What does
  $ pacman -Qs qt
give?

Re: Can't compile anything with qt3/qt4

I'm sorry for not testing my advises before giving them. 

I've just set up a qt4 and a qt3 hello world app using cmake.  For qt4 doing
  $ export QTDR=/usr
works, while qt3 needs
  $export QTDIR=/opt/qt

Hope that helps,

Re: Can't compile anything with qt3/qt4

for qt3:

 source /etc/profile.d/qt3.sh
  export QMAKESPEC=/opt/qt/mkspecs/linux-g++

for qt4:

  export QTDIR=/usr
  export QMAKESPEC=/usr/share/qt/mkspecs/linux-g++

Re: Can't compile anything with qt3/qt4

Does the configure skript offer an option where you can specify the qt-directory?

I got a similiar problem compiling something (don't ask me which program it was ) and I was able to solve it running the configure skript with a switch.... something like:

./configure -qt-dir=/place/qt/dir/here

Maybe you can find out with

./configure --help

Re: Can't compile anything with qt3/qt4

That wouldn't explain why the pkgbuild of kaffeine from the repo doesn't compile.
I tried it with   ./configure --prefix=/opt/kde  --with-qt-dir=/opt/qt  --with-qt-includes=/opt/qt/include --with-qt-libraries=opt/qt/lib --with-xorg
but the result was, yet again, the same.

Re: Can't compile anything with qt3/qt4

I have tried the PKGBUILD for kaffeine 0.8.6 (Extra repo), and I got no problem with the configure script which uses :
./configure --prefix=/opt/kde --with-xorg
...
checking for libjpeg... -ljpeg
checking for perl... /usr/bin/perl
checking for Qt... libraries /opt/qt/lib, headers /opt/qt/include using -mt
checking for moc... /opt/qt/bin/moc
...

I use kde and qt3 but I removed the qt-4 package for now.

echo $QTDIR
/opt/qt
echo $KDEDIR
/opt/kde

Maybe there is a conflict between the two qt versions on your machine.
