1. Install from distribution on ultibo.org
2. Next rebuild RTL to latest and greatest version

– download from github
– extract in {location}

Raspberry Pi

The next stepts, including the IDE (Lazarus for Ultibo) work file from the RPi console or over a XRDP or VNC connection.

Use the ultibo installer script, initially and to update to the latest and greatest version of Ultibo on github.

1. Copy the installer script over to the Pi, in the user pi home directory.

wget https://github.com/ultibohub/Tools/releases/download/1.0.5/ultiboinstaller.sh

2. Make the script executable

chmod +X ultiboinstaller.sh

2. Install dependencies (only needed on a fresh system)
Do the next steps in superuser mode. Convenient and otherwise it fails on an XRDP session

sudo su
apt-get update
apt-get upgrade

apt-get install -y libgtk2.0-dev libcairo2-dev libpango1.0-dev libgdk-pixbuf2.0-dev libatk1.0-dev libghc-x11-dev
apt-get install -y libx11-dev libgdk-pixbuf2.0-dev  gir1.2-coglpango-1.0  xorg-dev
apt-get install -y binutils-arm-none-eabi 

3. Increase swapfile

Because the Raspberry Pi only has 1024MB of memory at most, installation on Raspbian requires a swap file size of at least 1000MB, anything less may result in an error while building Lazarus.

nano /etc/dphys-swapfile

Edit the CONF_SWAPSIZE value to be 1000 or greater

sudo /etc/init.d/dphys-swapfile stop
sudo /etc/init.d/dphys-swapfile start
ls -lh /var
exit

And check that the file “swap” is now the size specified above

5. Now run script in user mod, the ‘exit’ in step 3 takes care of that. Takes a while!

6. After completion

Change swap back to 100, see step 3, in superuser mode!

The Lazarus IDE will now show up in Programming on the desktop.
