Code not compiling

rahuek · May 21, 2023, 8:38am

My Arduino Uno R3 hasn't been used for a while, and tried to use it today but got an error message when compiling:

fork/exec /Users/rahuek/Library/Arduino15/packages/arduino/tools/avr-gcc/7.3.0-atmel3.6.1-arduino7/bin/avr-g++: no such file or directory
Error compiling for board Arduino Uno.

The computer I'm using is a MacBook Pro Ventura 13.3.1
This is the full error message:

Arduino: 1.8.16 (Mac OS X), Board: "Arduino Uno"

Welcome to the forum

Your topic has been moved to the Programming category

J-M-L · May 21, 2023, 9:00am

can you check if this path exists on your Mac? you might need to reinstall the IDE

/Users/rahuek/Library/Arduino15/packages/arduino/tools/avr-gcc/7.3.0-atmel3.6.1-arduino7/bin

rahuek · May 21, 2023, 9:06am

It exists, but not avr-g++, don't know where that came from

J-M-L · May 21, 2023, 9:10am

installing the tools for AVR, but I thought this was coming wit the IDE.

I would suggest you download again the latest 1.8 version of the IDE (Arduino IDE 1.8.19) and install it and see if it fixed the issue

rahuek · May 21, 2023, 9:16am

Just downloaded 1.8.19, but it didn't fix the problem.

J-M-L · May 21, 2023, 9:23am

is this folder still empty ?

go to the board manager and see if the AVR package is installed (UI in French here but you should see something similar)

rahuek · May 21, 2023, 9:28am

Got it updated, but still doesn't work

J-M-L · May 21, 2023, 9:32am

do you have something in that directory?

/Users/rahuek/Library/Arduino15/packages/arduino/tools/avr-gcc/7.3.0-atmel3.6.1-arduino7/bin

Does the path exist?

rahuek · May 21, 2023, 9:35am

There are some things in the directory, but not the one the IDE is looking for.

J-M-L · May 21, 2023, 10:27am

Do a clean install

rahuek · May 21, 2023, 10:48am

how do you do that?

J-M-L · May 21, 2023, 1:16pm

I would delete the IDE app and the whole /Users/rahuek/Library/Arduino15 folder as well as the arduino preferences

Then reinstall from scratch and add the boards you need (like esp32) in the preferences and then use the board manager to install all the packages

@UKHeliBob
Hmm it still appears to be in the IDE 1.x category.
Thanks @UKHeliBob I wasn’t sure about that.

UKHeliBob · May 21, 2023, 6:04pm

That was not where it was originally posted and it has been moved on again since I first moved and I can see who did it. As it happens it is probably better off here so I will leave it alone
