[SOLVED] Building from source fails at 29% with QImage errors Vectorscope

Hi

First attempts at compiling from svn fails with:

[ 29%] Building CXX object src/cmake_bindir/CMakeFiles/kdenlive.dir/kdenlive_automoc.o
In file included from /home/yellow/Apps/kdenlive/src/cmake_bindir/kdenlive_automoc.cpp:4:

Any help would be appreciated.

KDE Dev libs listed in compile instructions are installed.

make clean, running cmake and make again does not help either?
Cannot reproduce here.

No still failing, I'm running Maverick Meerkat and using 'Cutting Edge Multimedia' PPA from the VDPAU Team maybe that has something to do with it.

Probably related to Qt 4.7 which is not released yet. What happens if you replace "class QImage;" by "#include < QImage>" (remove whitespace before QImage) in src/colorcorrection/vectorscopegenerator.h?

ttill, what is the reason for that? Why is this related to Qt? Isn't this just a C(++) question?
