Download and crosscompile Qt

wget http://download.qt.io/archive/qt/5.5/5.5.1/single/qt-everywhere-opensource-src-5.5.1.tar.xz
git clone [email protected]:raspberrypi/tools.git

tar xf qt-everywhere-opensource-src-5.5.1.tar.xz

export CROSS_COMPILE=`pwd`/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf-
export SYSROOT=`pwd`/sysroot

wget https://raw.githubusercontent.com/shahriman/cross-compile-tools/master/fixQualifiedLibraryPaths
chmod +x fixQualifiedLibraryPaths
./fixQualifiedLibraryPaths sysroot ${CROSS_COMPILE}gcc

cd qt-everywhere-opensource-src-5.5.1

Download and compile GStreamer

I had to do this inside an emulated environment, as I never got the autotools from GStreamer to configure correctly for crosscompiling.

wget http://gstreamer.freedesktop.org/src/gstreamer/gstreamer-1.6.1.tar.xz
wget http://gstreamer.freedesktop.org/src/orc/orc-0.4.24.tar.xz
wget http://gstreamer.freedesktop.org/src/gst-plugins-base/gst-plugins-base-1.6.1.tar.xz
wget http://gstreamer.freedesktop.org/src/gst-plugins-good/gst-plugins-good-1.6.1.tar.xz
wget http://gstreamer.freedesktop.org/src/gst-plugins-bad/gst-plugins-bad-1.6.1.tar.xz
wget http://gstreamer.freedesktop.org/src/gst-omx/gst-omx-1.2.0.tar.xz

sudo mkdir sysroot/build

Finished! Sysroot should now be setup and ready for compiling disupurei!
