How to compile on Raspberry Pi

Compile without systray support

1. In order to compile the Agent yourself, first you have to install golang. Please use version 1.14.15
2. Then clone the repository with git clone https://github.com/arduino/arduino-create-agent.git
3. Change directory to the newly created one# : cd arduino-create-agent/
4. And finally to build use go build -v -tags cli. The -tags cli flag is used to generate a binary that can be run headless without GUI or trayicon support.
5. start the binary with ./arduino-create-agent. If all went well you should see something like this in the terminal window:

Compile with systray support

Is possible to build also with tray icon support. In order to do so, you have to install first the libraries required for the tray icon with sudo apt install libappindicator3-dev gir1.2-appindicator3-0.1 libgtk-3-dev and then use sudo go build -v to build instead of step 4 in the previous section

Bonus

To start the binary without having to allocate a full terminal window to it you can run with the & operator and nohup: nohup ./arduino-create-agent &:

• & starts the program in the background
• nohup cashes the hangup signal and when the parent process is killed (the shell) it changes the parent to 1 (the init process)
