ESP32S3 cannot compile in any way due to conflicts

[markeby]

Async Demo will not compile. There is no way I could find to eliminate the conflicts. I changed the order of include files many different ways. This will not build!

Ditto. I am using Arduino IDE 2.2

Same here, using platformIO in VSCode. I'm looking back in the code to confirm, but I think that ELEGANTOTA_USE_ASYNC_WEBSERVER should be set to 1 and that isn't happening.

@JMWilton, I believe the FS_end and FS_start issue may be something different. Try #143 (comment)

@markeby try the instructions here, https://docs.elegantota.pro/async-mode/

This should solve your issue.

[ayushsharma82]

@markeby Did you get it working?

@markeby try the instructions here, https://docs.elegantota.pro/async-mode/

This should solve your issue.

Following the async docs and using the example code does not compile. Using the latest PlatformIO, building produces a ton of #error "include FreeRTOS.h" must appear in source files before "..." errors, beginning with this one:

In file included from .pio/libdeps/nodemcu-32s/AsyncTCP/src/AsyncTCP.h:29,
                 from src/main.cpp:29:
/Users/SomeUser/.platformio/packages/framework-arduinoespressif32/tools/sdk/esp32/include/freertos/include/freertos/semphr.h:31:6: error: #error "include FreeRTOS.h" must appear in source files before "include semphr.h"
     #error "include FreeRTOS.h" must appear in source files before "include semphr.h"

I resolved the various conflicts with a previous declaration errors by ensuring that AsyncTCP wasn't listed twice in /.pio/libdeps. Make sure that you're not listing AsyncTCP in your lib_deps, as ESPAsyncWebServer already brings that lib in for you.

lib_deps = 
  ayushsharma82/ElegantOTA@^3.1.0
  https://github.com/me-no-dev/ESPAsyncWebServer.git
  ; https://github.com/me-no-dev/AsyncTCP.git
build_flags=-DELEGANTOTA_USE_ASYNC_WEBSERVER=1

I also tried going into my /.pio/libdeps/*/ElegantOTA and updating the #define ELEGANTOTA_USE_ASYNC_WEBSERVER 1 flag myself (instead of using the build_flags), but without success.

FYI here is what I am using on a big project using ElegantOTA, ESH-DASH and which works on ESP32, ESP32S, ESP32S2, ESP32S3, with and without ethernet:

-D ELEGANTOTA_USE_ASYNC_WEBSERVER

lib_deps =
  bblanchon/ArduinoJson @ 7.0.3
  esphome/AsyncTCP-esphome @ 2.1.3
  mathieucarbou/ESP Async WebServer @ 2.7.0
