###this was done on a fresh 2015-01-31-raspbian.img

##install some libs
sudo apt-get install libboost-dev swig curl libgnutls-dev libxml2-dev libxslt1-dev libfreetype6-dev libfontconfig1-dev libfribidi-dev libmpeg2-4-dev libmad0-dev libjpeg8-dev libsamplerate0-dev libogg-dev libvorbis-dev libflac-dev libtiff4-dev liblzo2-dev cmake zip unzip libsqlite3-dev libpng12-dev libpcre3-dev libjasper-dev libsdl1.2-dev libsdl-image1.2-dev libass-dev libmodplug-dev libcdio-dev libtinyxml2-dev libyajl-dev libgpg-error-dev libgcrypt11-dev libmicrohttpd-dev autoconf libtool autopoint libudev-dev python-dev python-imaging libmysqlclient-dev  libcurl4-gnutls-dev libbz2-dev libtinyxml-dev libssh-dev libxrandr-dev libsmbclient-dev libcap-dev gawk gperf debhelper libiso9660-dev

###cloning master branch of kodi
git clone git://github.com/xbmc/xbmc.git

### apply manually in /configure.in and /tools/depends/configure.in to get new cpu optimizations
http://www.intestinate.com/pilfs/patches/xbmc-14.1-Helix-rpi2-target.patch
###

### optional, build new libcec (did not work afterwards, configure told cec support=yes, but cec not working in kodi!)
git clone git://github.com/Pulse-Eight/libcec.git
cd libcec
./bootstrap
./configure
make -j4
sudo make install
###

### do yourself a favor an do NEVER install libtag from repo, this took me quite some time to mess around with)
### more info http://forum.kodi.tv/showthread.php?tid=143269
### instead build included libtag
cd xbmc/lib/taglib
make -j4
sudo make install
cd
###


### and so it begins
cd xbmc
./bootstrap

### those options include way too much, but just wanted to check some things out, you may need to --disable-libcec
### takes some time due building ffmpeg

## yay 4 cores :-)
make -j4

##aaand install
sudo make install

###make keyboard work for non-root (here user 'pi' inside search-fields)
sudo usermod -aG tty pi
sudo su -c 'echo "KERNEL==\"tty[0-9]*\", GROUP=\"tty\", MODE=\"0660\"" >> /etc/udev/rules.d/99-input.rules'
