Code compiles for ESP8266 but not ESP32

1

Hi,
My code is compiling properly for ESP8266 but if it fails for ESP32
See the error and platformio.ini below.

How can I troubleshoot and fix it?

Retrieving maximum program size .pio/build/esp32/firmware.elf

I am using AutoConnect and it has the code like this.(from their own example)

#include <AutoConnect.h>

#ifdef AUTOCONNECT_USE_LITTLEFS
  #include <LittleFS.h>
  #if defined(ARDUINO_ARCH_ESP8266)
    FS& FlashFS = LittleFS;
  #elif defined(ARDUINO_ARCH_ESP32)
    fs::LittleFSFS& FlashFS = LittleFS;
  #endif
#else
  #include <FS.h>
  #include <SPIFFS.h>
  fs::SPIFFSFS& FlashFS = SPIFFS;
#endif


#include <ArduinoJson.h>

You set this in env:esp32_wokwi but not in env:esp32.

@maxgerhardt that works, but it doesn’t explain why the ESP8266 worked without it.

tks

o_O The Arduino-ESP8266 core is an entirely different codebase with vastly different flash usage compared to ESP32. The two are not easily comparible. ESP32 is much, much more bloated.

Thank you.
I am still learning my way around them
