Hello,
I was trying to compile qt-copy trunk... but I discovered Qt4.4 doesn't lik=
e=20
gcc 4.1.2:
    -no-xmlpatterns..... Do not build the QtXmlPatterns module.
 +  -xmlpatterns........ Build the QtXmlPatterns module.
                         QtXmlPatterns is built if a decent C++ compiler
                         is used and exceptions are enabled.

I also disabled the QtXmlPatterns module:

=2E/configure -qt-gif -no-exceptions -fast -prefix=20
$QTDIR -confirm-license -no-xmlpatterns

during a normal configure of Qt4.4 (a configure without any options) I got=
=20
directly:
=2E..
QtXmlPatterns module  no
Phonon module ....... no
=2E..

So If it disables the QtXmlPatterns why then it wants to link against it?
Was this bug known? Will be fixed in the next snapshots versions, won't it?

And Phonon... I have not installed gstreamer so I can understand it's been=
=20
disabled, but I've got xine installed with all xine libs includes... Phonon=
=20
wasn't based on xine backend too?
