Exit status 1

I’m new on Arduino … i’m getting this error when compiling my program.
How to approach this ?

C:\Program Files\WindowsApps\ArduinoLLC.ArduinoIDE_1.8.15.0_x86__mdqgnx93n4wtt\libraries\Ethernet\src\EthernetClient.cpp: In member function ‘connect’:

I’m adding my code also …:

Looks like you're using the windows store app. Get rid of it and install the normal version and try again.

Programming questions are for problems with your code :wink: This is not a problem with your code.

Personal opinion: install IDE 1.8.5, not 1.8.7

This bug is specific to the 5.4.0-atmel3.6.1-arduino2 version of avr-gcc used by Arduino AVR Boards 1.6.22 and newer. It has been reported here:

Here's the workaround:

  • Tools > Board > Boards Manager
  • Wait for downloads to finish.
  • When you move the mouse pointer over "Arduino AVR Boards", you will see a "Select version" dropdown menu appear. Select "1.6.21".
  • Click "Install".
  • Wait for installation to finish.
  • Click "Close".

Due to a bug, this workaround doesn't work with Arduino IDE 1.8.6, but it will work with any other version of the Arduino IDE.

If you have File > Preferences > Check for updates on startup checked, the Arduino IDE may occasionally notify you that a new version of Arduino AVR Boards is available, you'll need to refrain from updating back to the new Arduino AVR Boards version, otherwise you'll be back to seeing the segmentation fault error again.

Many thx to pert, this solved my problem
