Historical RaspberryPi, Revision 20

Installing Euphoria on the Raspberry Pi

The current Euphoria 4.1.0 Beta2 can run on the Raspberry Pi.

See step-by-step Installation instructions below.

Building Euphoria for the Raspberry Pi



Example programs




Installing Euphoria and EuGTK on Raspberry Pi 3 with Raspbian:

Follow the links on the Euphoria 4.1.0 Beta2 page to download Euphoria 4.1 beta 2 arm binary for manual installation

Download the editor: WEE-master.zip.
Use archiver to extract to /home/pi (or /home/your_user_name)

Download the latest EuGTK, and click on the tar.gz file, read the important note, then drag the demos folder into your home folder. You'll now have a /home/pi/demos folder (or /home/<yourname>/demos)

Go to your home folder, and open a terminal to copy some files:

cd /euphoria-4.1.0-ARMv6-hardfloat/bin
sudo cp * /usr/bin
cd ..
sudo mkdir /usr/share/euphoria
sudo chmod 777 /usr/share/euphoria
sudo rm /usr/bin/eu.cfg
cp -r * /usr/share/euphoria

Confirm that eui is installed
Type eui at the command line:
pi@raspberrypi: $ eui
Euphoria Interpreter v4.1.0 development
32-bit Linux, Using System Memory
Revision Date: 2015-02-02 14:18:53, Id: 5861:57179171dbed

ERROR: Must specify the file to be interpreted on the command line

(So far, so good!)

Replace /usr/bin/eu.cfg with the following: (will probably have to use sudo nano to do this)

-eudir /usr/share/euphoria
-i /usr/share/euphoria/include

-arch ARM
-com /usr/share/euphoria
-lib-pic /usr/share/euphoria/bin/euso.a
-lib /usr/share/euphoria/bin/eu.a

-eub /usr/share/euphoria/bin/eub

Check that it works In a terminal, type:

cd /demos
eui test0

Should take a few seconds, and then show a nice window with info about GTK, EuGTK, current platform, etc.

Associate .ex files

  • Use file manager to navigate to /demos
  • Right-click on test0.ex or one of the other test*.ex files
  • Select Properties from the popup window
  • Select Open With -> Customize
  • Click on Custom Command Line
  • Enter eui as Command line to execute:
  • Enter Euphoria as the Application name
  • Click OK

Double click on an .ex program to see if it works.


When using the GtkWebKit or GtkSourceView plugins on Pi with Raspbian, you'll need to edit the tops of those files to indicate the location of the libraries:

For GtkSourceView.plugin:

object sourceviews = dir("/usr/lib/arm-linux-gnueabihf/libgtksourceview-3*")

For GtkWebKit.plugin:

object webkits = dir("/usr/lib/arm-linux-gnueabihf/libwebkit2gtk-3*")

(You can use version -4 of these two libraries if you have them available.)

If you are going to write your own GUI programs with EuGTK, you will need the GTK3 Docs.

I have found it works best to extract the gtk3-html-3....tar.gz folder to my home folder (/home/pi) and rename the folder to just plain gtk3. That makes the docs easier to find.

You may also want to edit /demos/bear/bear.ex line 10 to point to your gtk3 docs. eu_help_path = "/home/pi/gtk3" should work.

The Raspberry Pi 3 is a bit slow, so binding your Euphoria programs is helpful. Especially WEE and other programs you will use frequently.

Translating and compiling large EuGTK programs on the Pi is also rather slow, so you may prefer to cross-compile on a full-size PC, and then copy the executable to the Pi.
