I'm trying to compile QtAV but run into problems I can't solve! No solution on Google either. I would really, really appreciate any help/advice you may have for me.

I'm on :
Linux 3.11-2-amd64 #1 SMP Debian 3.11.10-1 (2013-12-04) x86_64 GNU/Linux
(aka SolydK - testing).
ffmpeg local build - works, opencv-2.4.7 local build - works

on make: the following error occurs:

g++ -c -m64 -pipe -isystem /home/leon/qt/QtAV/src -isystem /home/leon/qt/QtAV/src/.. -O2 -Wall -W -D_REENTRANT -fPIC -DBUILD_QTAV_LIB -D__STDC_CONSTANT_MACROS -DQTAV_HAVE_SWRESAMPLE=1 -DQTAV_HAVE_PORTAUDIO=1 -DQTAV_HAVE_OPENAL=1 -DQTAV_HAVE_XV=1 -DQTAV_HAVE_GL=1 -DQTAV_HAVE_VAAPI=1 -DQT_NO_DEBUG -DQT_OPENGL_LIB -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -I/usr/share/qt5/mkspecs/linux-g++-64 -I/home/leon/qt/QtAV/src -I/home/leon/qt/QtAV/src -I/home/leon/qt/QtAV -I/home/leon/qt/QtAV/src/QtAV -I/usr/include/qt5 -I/usr/include/qt5/QtOpenGL -I/usr/include/qt5/QtWidgets -I/usr/include/qt5/QtGui -I/usr/include/qt5/QtGui/5.1.1 -I/usr/include/qt5/QtGui/5.1.1/QtGui -I/usr/include/qt5/QtCore -I../.moc/5.1.1/QtAV -I. -o ../.obj/QtAV_linux_x86_64/XVRenderer.o /home/leon/qt/QtAV/src/XVRenderer.cpp

There is no "qplatformnativeinterface.h" on my Qt5 installation or anywhere else on my system.

Thanks so much in advance, I really appreciate any help.
