Fixing Error compiling for Arduino Uno

hi I am having a hard time trying to understand this error message, it says missing library, but i Am unsure which library to reinstall. I have tried to reinstall the arduino agent, I havve also tried using the online version of arduno create, but the same error message appeared.. this is the error message "Arduino: 1.8.19 (Mac OS X), Board: "Arduino Uno"

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

fork/exec /Users/AryanGorai/Library/Arduino15/packages/arduino/tools/avr-gcc/7.3.0-atmel3.6.1-arduino7/bin/avr-g++: no such file or directory

Please do not post pictures of code. Post the full sketch in code tags along with the full error message, also in code tags, and details of the Arduino board that you are using

Your topic was MOVED to its current forum category as it is more suitable than the original

Sorry, I have updated the forum question with the right code and error messages in code format now..

It compiles OK for me, also using 1.8.19 on Mac OS X 12.4. I suspect your Arduino installation got damaged. The most reliable way to fix it is to re-install the whole IDE.

Note: There is a compiler warning about this line:

        if (c = '\n')

It should almost certainly be:

        if (c == '\n')

@Aryan-Gorai,
Your topic was moved by @UKHeliBob to programming questions, why did you move it back to installation and troubleshooting? This is a programming question, please leave it there.

It's not a library in the sense of "Arduino library". Your installation is missing the compiler (avr-gcc++). I'm not a Mac user so can't quite advise.

  1. When you re-installed, did you delete the directory /Users/AryanGorai/Library/Arduino15 before re-installing? That would be the first thing to do.
  2. The download of the IDE might be corrupt in some way; download it again and retry.

HMm How would i delete the directory.. Yes I have tried. multipiple times deleing and reinstalling the ide, however it does not seem to fix the issue. Pls advise me on how to delete the directory and I will try again.. thanks
