Building from the sources on Linux ARM

Building the Pro IDE on Linux armv7l (aka armhf) and aarch64 (aka arm64):

1. Install Node.js 16.x with nvm:

   wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
   

   Restart your shell then:

   nvm install 16
   nvm use 16
   

   Verify:

   node -v
   

2. Install Yarn:

   Configure the Debian package repository; otherwise, you will pull a different yarn.

   curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
   echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
   

   Install:

   sudo apt update && sudo apt install --no-install-recommends yarn
   

   Verify:

   yarn -v
   1.22.4
   

3. Other native dependencies:

   • make,
   • gcc,
   • pkg-config,
   • build-essential,
   • libx11-dev, and
   • libxkbfile-dev

4. Build it from the source:

   git clone https://github.com/arduino/arduino-ide.git \
   && cd arduino-ide \
   && yarn \
   && yarn rebuild:electron \
   && yarn --cwd ./electron-app start
   

5. Troubleshoot

   If you see ENOSPC errors at runtime, increase the default inotify watches:

   echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
