(I looked first if others had this problem but could not find it here.)
So I’ve got a Compiler error:

/home/erik/SynologyDrive/Arduino/libraries/Adafruit_Sensor/Adafruit_Sensor.cpp:2:10: fatal error: avr/pgmspace.h: No such file or directory
2 | #include <avr/pgmspace.h>
| ^~~~~~~~~~~~~~~~
compilation terminated.
exit status 1

Ebook: Learn LVGL: Build GUIs for ESP32 Projects, PAGE: 162

I found a solution after some searching:

REMOVE the #include <avr/pgmspace.h> line from Adafruit_Sensor.cpp
OR change the line to: #include <pgmspace.h>

Adafruit_Sensor.cpp content: /home/erik/SynologyDrive/Arduino/libraries/Adafruit_Sensor
——————————————————————

#include “Adafruit_Sensor.h”
#include <avr/pgmspace.h>
void Adafruit_Sensor::constructor() {
}

So AFTER the mentioned changes compiling is OK and everything seems to be working.
But this is not as it should be??
What could be the matter?
Thanks, Erik
