This tutorial provides Raspberry Pi specific installation instructions and general remarks to work with the SmartMDSD Toolchain and the Raspberry Pi.

This tutorial will install SmartSoft on the RaspberryPi. The installation is based on Raspbian Stretch Operating System with desktop for the RaspberryPi.

This tutorial uses the official installer but adapts some steps specifically for the RaspberryPi. In summary, it differs as follows:

• Use compiler GCC 5 instead of RaspberryPi's default compiler
• Do not install the SmartMDSD Toolchain on the PI: the PI is only used to execute components.

Note: Development of software components on the PI will not work with the binary release of the SmartMDSD Toolchain as they are compiled for i86 architectures, not for ARM.

Before we install SmartSoft, open a terminal and execute the following commands in order to install a compatible C++ compiler and Xterm on your Raspberry Pi:

sudo apt-get install xterm 
 
sudo apt-get install gcc-5 g++-5 
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-5 1 
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 1 

Verify that your compiler is g++ version 5 by writing in terminal “g++ -v”

If you see the gcc version 5.* you are ready to proceed

Create a folder in your home directory on Raspberry Pi and start the installation by writing in terminal:

mkdir ~/SOFTWARE/ 
cd ~/SOFTWARE/ 
wget https://github.com/Servicerobotics-Ulm/UtilityRepository/raw/master/smartsoft-install-updatescript.sh 
bash smartsoft-install-updatescript.sh 

In the installer menu, uncheck option 2 “Update/Install SmartMDSD Toolchain to latest version”, since the precompiled binary will not work on ARM. Press 'OK'.

Be aware that a similar looking window may pop-up. Don`t confuse them. In the Install ACE/SmartSoft and dependencies on a clean system window, uncheck option 1.4)Install additional generic packages (optional) and press 'OK'.

Installation may take some time. Don`t worry, it`s fine.

During installation, depending on the Raspbian distribution, an error may occur. Then you will see this window asking if you want to abort the update script. Press 'No'.

If the following window pops up, choose 'Yes'.

Once Installation is done, if you see the selected line, the installation process is finished:

Go to ~/SOFTWARE/smartsoft directory

Start the naming service using the following command:

./startSmartSoftNaming service

Once the naming service is running, start exampleComponent101 by writing in terminal:

bin/exampleComponent101

If you see this - you have successfully installed SmartSoft on your Raspberry Pi!
