Arduino

Installing Arduino IDE on OLPC OS.

12.1.0

Switch to the GNOME desktop.

Packages

sudo yum install -y arduino

Roughly 43 MB of packages are downloaded and installed.

Fix Access

The IDE requires that the user be a member of the lock group. See also <trac>11972</trac>. This also restarts GNOME.

sudo groupmems --group lock --add olpc && \
   sudo systemctl restart prefdm.service
