Raspbian Still Bad
The command “sudo apt-get install arduino” doesn’t get you the Arduino development environment. Instead, when you try to run it from the command line, you get “Error occured during initialization of VM. Server VM is only supported on ARMv7+ VFP”. I get that cross-compilation can be tricky, but this software didn’t get released, it escaped. Arduino isn’t exactly an obscure package.
To be fair, this isn’t because Arduino is broken. It’s because apt automatically chooses a version of Java that can’t run on the Zero W. So any package that uses Java is probably also broken, but I’m not looking into it, because I’m trying to actually do something with the Raspberry Pi. If I wanted to fuck around with a broken package chain, I’d… have gotten my fill of that like 10-13 years ago, so I guess I’d need a time machine. Really, the Pi Zero W is a lot like a time machine, taking me back to a time when Linux was a project, rather than being something you can use for projects.
If you, for some reason, want to use the Arduino IDE on a Pi Zero W, the incantation is to install Java 8 with ‘sudo apt-get install openjdk-8-jre-headless openjdk-8-jre’ and then use ‘sudo update-alternatives –config java’. Then you”ll be running a 5 year old Java and a 6 year old Arduino IDE, but at least the IDE will start up.
