ESP32 AsyncWebServer

I currently trying to setup an Async Web Server on the ESP32. But unfortunately I don't get the code to run. I'm usign platform io on windows 10.

#include <Arduino.h>
#include <ESPAsyncWebServer.h>

const char* ssid = "myAP";
const char* password = "123456789";

AsyncWebServer server(80);

setup() and loop() are empty. If I try to compile the code these message shows up. 

compilation terminated.

had the same issue, downgrading the core of PlatformIO solved for me the issue.

pip install -U "platformio<4.2.0"

You're using the wrong async TCP library. The one you're using is for the ESP8266, not the ESP32.

Here's its PlatformIO library registry entry:

https://platformio.org/lib/show/305/ESPAsyncTCP

enter image description here

You're seeing errors because it's trying to call functions that are available on the ESP8266 and not the ESP32.

You want the AsyncTCP library:

https://platformio.org/lib/show/1826/AsyncTCP

You should update your platformio.lib file to include this library instead of ESPAsyncTCP. You may also need to remove the build or library directory to get rid of the old library.
