bits/error_constants.h missing

[igoeco]

Description
I successfully used the ArduinoJSON library on another machine. When I try to run the code on a different machine (using ArduinoIDE), it first complained that ArduinoJSON was not installed on line:
#include <ArduinoJson.h>
So, I used the "Manage Libraries" tool and successfully installed the latest version 6.20.0.
Now I get an error saying:
c:\users\myusername\appdata\local\arduino15\packages\esp32\tools\xtensa-esp32-elf-gcc\gcc8_4_0-esp-2021r2-patch5\xtensa-esp32-elf\include\c++\8.4.0\system_error:39:10: fatal error: bits/error_constants.h: No such file or directory

Clearly, I do not have the file but I am not sure why?

Here are a few more details:
ArduinoIDE version: 2.0.3
Device: ESP32 WROVER Dev

Thanks for your help.

PS: I have an identical setup on my other machine except it is Windows 11 and not 10

Hi @igoeco,

It seems to be an issue with the ESP32 core.
espressif/arduino-esp32#6593

If you don't have this file, then it's probably a problem with your installation.
Please try to reinstall the ESP32 core.

Several people mentioned an issue with the path length; maybe you can try to shorten it.

Best regards,
Benoit

I've figured it out and proved it to my satisfaction.

Executive summary:

I was getting the failure. I removed two nodes from my path length and it's FIXED. Your suggestion WAS CORRECT!

Detail:

The path was somewhat long - It was c:/users/jed/OneDrive/electronics/RunableCode/Arduino-1.8.19 then the included files. 1.8.13 worked like that until OneDrive messed it up by adding extra files when I tried to use the IDE while it was syncing and it duplicated some. I installed 1.8.19 to fix and it was failing with the error above. By moving the folder up directly into OneDrive, I fixed it. (yes, those are the wrong / for Windoze but the damn \ hurts my pinky to type and I'm bilingual anyway). I don't know where the limitation is, but it isn't windows because I've found failures reported under Linux AND I changed my W10 registry to allow longer paths AND I also tested on W11 (easy because on OneDrive on both desktops and my laptop) and it failed everywhere UNTIL I copied from OneDrive to my W11 C: That suggested it was the path so I went back to OneDrive and up two levels so it was directly under OneDrive and now it works on both W10 and W11 when running from OneDrive.

Note that Arduino IDE 1.8.19 AND 2.0.3 both fail with the same message. I'd bet it's a limitation in gcc library paths.

Try it - you'll LIKE it!

BTW: I LOVE ArduinoJson! I use it to filter then parse api.weather.gov and it makes my "sketch" easy. Thank you**10**6
