Error compiling for board Arduino Uno - Sorry - again

Development Tools IDE 1.x
1

Hello... I'm sorry to post such a basic thing, but I'm finding this error hard to decypher. I'm getting it whenever I upload anything to my board. It was working fine, and then it just stopped. I since upgraded my Arduino software, and now can't do anything.

Here's the error I'm getting. My port and board are set to Arduino Uno.

Arduino: 1.8.19 (Mac OS X), Board: "Arduino Uno"

Error compiling for board Arduino Uno.

The only advise that I can give is to check if that file exists.

3

That's so weird. I can't find it. I've tried uninstalling and installing the software, but it's still referencing the same file.

4

OK... I found the Library folder. Yeah... the avr-g++ file doesn't exist. Troubleshooting! Thanks sterretje!

5

So you can now compile?

6

No... not yet. I'm trying to figure out what's requiring that file. I downgraded the board manager, and I'm still getting the same error.

7

Nearly everything requires that file; it's the compiler.

Google may help: mac Arduino15/packages/arduino/tools/avr-gcc/7.3.0-atmel3.6.1-arduino7/bin/avr-g++ - Google Search

You will have to dig through the topics; I have never encountered the problem and I don't have a Mac to look at it. avr-g++: no such file or directory - #4 by pert worked for the user that had the problem, it might help for you.

Wooohoo! Thanks for helping me out with that. If I could, I'd send you a sticker! :grinning:
