Arduino check/compile fail: "as not found" or "mmcu=avr5 not recognised"

New Tumbleweed user here!
Latest Tumbleweed as of tonight.
After installation of arduino ide as per “SDB:Arduino IDE - openSUSE Wiki” check/compile of sketch fails with “as not found” or “mmcu=avr5 not recognised” depending on whether regular dev tools are intalled or not.
Console or 1klick install works the same on two machines…
Most likely new user error but I am stuck at the moment, any pointers, please ?

You might have less issue(s) if you install Arduino as a Flatpak. Start up Discover, then for All Applications, enter “arduino” in the Search box, then execute search.

Choose the Arduino entry - be sure to read any suggestions, then if you’re ready, click Install. Then run it and see if it’s trouble-free. Sometimes, Flatpaks (for unique software) are easier to install (and remove, if need be) and simpler to run.

Thank you aggie, great advice!

Works like a charm and will use for now although I lost 515 instead of 50 odd MB’s

OTOH I’d like to learn what is needed to make the console install work, if at all possible.

Anyone willing to walk me through this ?

Glad it worked

Obviously the reason (as a rule) is everything required to run the app is bundled in the Flatpak. Hence, the additional space required. It’s very similar to running an OS in a virtual machine.

It’s a trade-off that is sometimes worth it. Do you want to spend 2-3 minutes installing a Flatpak, or 1+ hours trying to do it otherwise

And waaaaaay less complications with regard to installing a bunch of required components from one or more non-default repositories (for a non-Flatpak install). Heck, some distros only rely on software installed as Flatpaks (hint).

Sorry, no suggestions on the “console install” from me - good luck! (maybe post at vendor forum for hints)
