thanks for your recommendation, in the following order it compiles now without any error! <Audio.h> was the problem ...

#include "FS.h"
#include "SD_MMC.h"
#include "SPI.h"
#include <WiFi.h>
#include <WebServer.h>
#include <Update.h>  	  // Web OTA

#include "IRremotePinDefinitions.h"
#include <IRremote.hpp>

#include <Audio.h>    // include after IRremote!
#include <Preferences.h>  // NV speicher
#include "DS3231.h"       // RTC (EEPROM I2C adr 0x57)
#include <Wire.h>
#include <PCF8574.h>
#include <WiFiClient.h>
//#include <WiFiClientSecure.h>
#include <ArduinoJson.h>

Maybe wrong compiler or wrong processor.

in both cases i use arduino IDE 233 with the AI Thinker ESP32-CAM board. the above error only appears in my user design, not in the IRremote Demo sketch. I don't have an idea whats wrong ...

this are all my includes:

#include <Arduino.h>
#include "FS.h"
#include "SD_MMC.h"
#include "SPI.h"
#include <WiFi.h>
#include <WebServer.h>
#include <Update.h>  	  // Web OTA
#include "Audio.h"
#include <Preferences.h>  // NV speicher
#include "IRremotePinDefinitions.h"   // just renamed the file PinDefinitionsAndMore.h
#include <IRremote.hpp>
#include "DS3231.h"       // RTC (EEPROM I2C adr 0x57)
#include <Wire.h>
#include <PCF8574.h>
#include <WiFiClientSecure.h>
#include <ArduinoJson.h>

Then I guess one of the other libs are not compatible.
Move the lines

#include "IRremotePinDefinitions.h"   // just renamed the file PinDefinitionsAndMore.h
#include <IRremote.hpp>

upwards until the error vanishes and report your result.
