Unclear reference to WebSocketsServer.h, file not found

[Joennuh]

In release 4.15.11 somewhere jsonFmt.h / jsonFmt.cpp is referenced resulting in an error saying WebSocketsServer.h could not befound. When I do a search with Github on the files of the repository I can't find any link to those 3 files. Also I didn't put an include to any of those 3 files.

The error is:

In file included from C:\Users\*****\Documents\Arduino\libraries\ArduinoMenu-master\src\menuIO\jsonFmt.h:9:0,

                 from C:\Users\*****\Documents\Arduino\libraries\ArduinoMenu-master\src\menuIO\jsonFmt.cpp:3:

C:\Users\*****\Documents\Arduino\libraries\ArduinoMenu-master\src\menuIO\esp8266Out.h:9:32: fatal error: WebSocketsServer.h: No such file or directory

   #include <WebSocketsServer.h>

                                ^

compilation terminated.

The includes I use in my testproject:

#include <Arduino.h>
#include <menu.h>
#include <menuIO/u8g2Out.h>
#include <menuIO/serialIn.h>
#include <menuIO/serialOut.h>
#include <menuIO/altKeyIn.h>
#include <menuIO/chainStream.h>
#include <Wire.h>

My testproject runs on a Wemos D1 mini clone (ESP8266) with U8G2 compatible 128x64 OLED screen and 3 buttons (1 internal pull up, 2 external pull up).

indeed, documentation is always not as good as desirable, sorry for that, I will add some notes about the extra library sources url...
meanwhile, I'm using libraries from here https://github.com/esp8266/Arduino and websockets library from here https://github.com/Links2004/arduinoWebSockets

arduinomenu wiki edit is also open to public...

thanks for testing and reporting things like this :D

@neu-rah You're welcome. I'm just trying to see whether I can use a good menu-system on my testproject with my noobisch knowledge and experience. Even more I try to understand and learn to use the Arduino language and libraries.

I'm still wondering why I got errors about jsonFmt.h, jsonFmt.cpp and WebSocketsServer.h while I never put any reference to any of these 3 files. I also couldn't find any reference from other files to the mentioned 3 files so far. Is there any reason why these 3 files are referenced whilst I did not include websockets or ESP8266 web output?

[neu-rah]

the webmenu example is specific for esp8266 family, the driver includes those file and requires that those libraries be present/installed. Fell free to ask here, on gitter chat room or by email. I'm glad to help.

gitter chat room here: https://gitter.im/ArduinoMenu/Lobby

But I didn't use the webmenu example and that's why I'm wondering why the mentioned files are referenced / included. I can't find any reference / link to it.

I have never heard of Gitter but I signed up on it now.
