array library not found

When attempting to compile any examples for the arduino, I get:

In file included from C:\Users\iviti\sketchbook\libraries\MyCobotBasic/MyCobotSaver.h:5:0,

Error compiling for board Arduino Mega or Mega 2560.

Hey! Did you end up solving this issue?

I think this is related to the avr-libstdcpp mentioned in 10.3 Use of the Arduino library.

Okay, I've managed to fix this by following the instructions in Chinese here. It requires copying and pasting the lib\avr-libstdcpp folder included with the MyCobotBasic repository into your computer's Arduino/libraries folder.

But now I am getting another error:

In file included from ~/Documents/Arduino/libraries/avr-libstdcpp/new_handler.cc:26:0:
~/Documents/Arduino/libraries/avr-libstdcpp/new:40:10: fatal error: stddef: No such file or directory
 #include <stddef>
          ^~~~~~~~
compilation terminated.
exit status 1

Compilation error: exit status 1

If I edit avr-libstdcpp/new#L40 like this

- #include <stddef>
+ #include <cstddef>

then I get lots of other errors:

So I am not sure if that is the correct fix...

[didmou]

Hello, I had exactly the same problem, to solve it, have use the IDE Arduino 1.8.19 !!! And NOT IDE Arduino 2.3.3 !!!
I don't know why exactly there is this difference... but if it's can help ...
