Hey! So currently i want to make a websocket client with an Arduino mega 2560. My problem is that every time i download a websocket client package from the GitHub i get errors like these:

*\ArduinoWebsocketClientmaster\WebSocketClient.cpp:30:1: error: 'prog_char' does not name a type; did you mean 'putchar'?
 prog_char stringVar[] PROGMEM = "{0}";
 ^~~~~~~~~

(At the last one i deleted my 2.0.0 IDE and installed the 1.8.9 but nothing changed.)
Can any1 help me please? Thank you

Did you read the error message, particularly

currently does not support Arduino with AVR

What processor architecture does the Mega2560 use ?

Did you try V1.3.0 of this one?

WebSockets for Arduino (Server + Client)
use 2.x.x for ESP and 1.3 for AVR

You can download it from:
https://downloads.arduino.cc/libraries/github.com/Links2004/WebSockets-1.3.0.zip

In this error message, the "2.x.x" is referring to the version of the "WebSockets" library, not to the version of the Arduino IDE.
