Failed to compile simple project having ESPAsyncWebServer

What happened?

I get fails compiling my simple project using ESPAsyncWebServer as dependency (only using AsyncTCP as dependency do compile).
My plattform.io-file:

[env:esp32thing]
platform = espressif32
board = esp32thing
framework = arduino
build_flags =
-DCORE_DEBUG_LEVEL=5
-Wno-unused-variable
monitor_speed = 115200
monitor_filters = esp32_exception_decoder, log2file
lib_deps =
FastLED
ESP32Async/AsyncTCP@^3.4.4
ESP32Async/ESPAsyncWebServer@^3.7.8

I have tried older 3.7.x releases, but get the same error. I have tried the old me-no-dev versions of AsyncTCP and ESPAsyncWebServer and they do compile (however they are so unstable in runtime so they are unusable).

I have reinstalled framework-arduinoespressif32 several times, but get the same error.

Minimal Reproductible Example (MRE)

https://github.com/trycoon/fackla

I confirm that:

• I have read the documentation.
• I have searched for similar discussions.
• I have searched for similar issues.
• I have looked at the examples.
• I have upgraded to the lasted version of ESPAsyncWebServer (and AsyncTCP for ESP32).

Hello,

This is more a support issue than a bug.

Please first try to compile one of the example with your board and also try to provide a MRE. I do not see any code.

Thank you!

[trycoon]

The code is in the repo https://github.com/trycoon/fackla.
Yes I forgot to change the label from a "bug" to a "issue".

Anyway, its working now.. The problem was the #include order in main.cpp that somehow got messed up. Sorry.

[mathieucarbou]

Yes I forgot to change the label from a "bug" to a "issue".

That's neither a bug nor an issue. A bug (or issue) is linked to the code in the library - something not working properly for example.

Here, this is a usage problem, so this is has to be in a support discussion.

Lot of people tend to mix both concepts ;-)
