SmartKegerator v2 Installation Guide

Project source here
This project has been heavily modified to take advantage of the raspberry pi 2’s additional horsepower. If you are looking for the raspberry pi v1 code, look around version 62 in the repository. Version 70 and on are unlikely to work on the original pi, although I have not tried.

[Updated 10/4/2016: These instructions have been updated and now work with a clean raspbianPIXEL image]


Install a new copy of raspbian onto an sd card.

On your first boot, configure these:
Expand Filesystem
Boot to Desktop
Enable Camera
Configure keyboard (if not in UK) and timezone
Finish > Reboot

1) Update raspbian

sudo apt-get update
sudo apt-get upgrade
sudo rpi-update

2) Install requisites

sudo apt-get install qtcreator cmake libopencv-dev mplayer subversion qt4-dev-tools libqt4-dev libqt4-dev-bin qt4-qmake

3) Configure QtCreator

Launch QtCreator from start menu > Programming > QT Creator

Once in QT Creator:
Tools > Options > Build & Run > Qt Versions > Add > navigate to or paste: /usr/bin/qmake-qt4
Tools > Options > Build & Run > Compilers > Add > pick GCC
Then set compiler path : /usr/bin/arm-linux-gnueabihf-gcc-4.9
Click OK

Qt Creator seems to think that we are going to deploy on a remote target, to fix this :
Help > About Plugins
Uncheck Device Support > Remote Linux
Click Close and reopen Qt Creator

Tools > Options > Build & Run > Kits > Desktop-Qt4 4.8.6 (qt4)
Compiler: GCC
Debugger : /usr/bin/gdb

4) Compile facial recognition libraries

cd ~
git clone
cd libfacerec
sudo cmake .
sudo make

5) Compile QWT

cd ~
mkdir qwt
cd qwt
svn co svn:// ./
sudo make
sudo make install
cd lib/
sudo cp * /usr/lib/

6) Compile WiringPi

cd ~
git clone git://
cd wiringPi/

7) Get SmartKegerator source

cd ~
mkdir qt
cd qt/
mkdir SmartKegerator
cd SmartKegerator/
svn co ./

8) Edit config files

sudo nano ~/qt/SmartKegerator/config.txt

Make sure all of the paths are correct for your system. If you’re using a fresh copy of raspbian and followed each step here, you shouldn’t need to edit anything.

9) Run it!

Open QTCreator and File > Open Project > /home/pi/qt/SmartKegerator/

Click Yes when it asks about environment settings.

Click the green arrow on the bottom-left to start building. The first build will take a while. If everything worked you should see the application open! If you get errors, try google or come back here and post a comment.

9) Disable the screen saver

sudo nano /etc/lightdm/lightdm.conf

scroll down until you see


Remove the starting ‘#’ from ‘#xserver-command=X” and add ” -s 0 -dpms” to the end so you have:

xserver-command=X -s 0 -dpms

ctrl-x, y, enter to save
