Being that my previous attempt of installing the Openbravo ERP solution on the Raspberry Pi failed, I have decided to switch to the LemonPOS package. This has turned out to be much easier than installing Openbravo
All of these following steps will be performed in the terminal.
The first step is to make sure everything is up to date
sudo apt-get update
sudo apt-get upgrade
Now that everything is up to date, we can install the needed packages
sudo apt-get install kde-standard libqt4-dev
While kde is installed, it will prompt you to either choose LightDM or KDE. Being that we already have LXDE, we can choose LightDM since it has less resouces to install.
Once you have KDE, and QT4 installed, we can install mysql
sudo apt-get install mysql-client mysql-server
Now we need to install everything else that’s needed for the compile
sudo apt-get install build-essential g++ cmake gettext libqt4-sql-mysql kdelibs5-dev
The next step is to download the source, and move it over to the pi. You can get the source from sourceforge Click here to download latest release
You will need to either use sftp or scp to move the tarball to the pi.
After transferring the source to the pi, find it’s location. I put mine in /home/pi/Downloads
tar -jxvf lemonpos-0.9.4-rc7.tar.bz2
Once it's finished extracting the tarball, move into the newly created directory, and create a 'build' Direcotry and move into it
Run CMake with your path to KDE4
cmake .. -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix`
Run make to compile lemonpos. This took about an hour on my pi
After the compile is finished, you will need to install everything
sudo make install
After everything is installed, we need to set up the initial database where everything will be stored
cat lemon_mysql.sql | mysql -u root -p
I haven't confirmed if the next step is needed, but I did it anyways just in case
cat mexico_taxes.sql | mysql -u root -p
You now have a working installation of LemonPOS! The next step is to set everything up. The username and password are set to the default of:
You can now go to the desktop, and run squeeze to set up all your items, and prices. After Squeeze is all set up, you can start using LemonPOS.
I decided that I wanted LemonPOS to start every time the desktop is loaded. To do this, you will need to add this line to the end of
This will make it so everytime the desktop is started, Lemon will start with it.
Now that everything is installed, you can go read the Users guide on SourceForge.net
