Using the cloud compiler, when I include the ESP8266WiFi library, I get:
fatal error:
LwipIntf.h: No such file or directory
#include "LwipIntf.h"
^
compilation terminated.
Any clues for a fix is appreciated.
BTW program works fine with computer IDE
Please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'
Use code tags (the </> icon above the compose window) to make it easier to read and copy for examination
Did you load/install the LwipIntf.h library?
@Idahowalker LwipIntf.h is in the esp8266 core
@Bill_H please add more details
Thanks for the info.
When something does not compile in ESP8266, I try with core 2.7.3 (no guarantee)
Thanks for the reply and advice. It's been a while since I used a forum...
I am simply trying to get the ESP8622 ( NodeMCU 1.0 (ESP-12E Module)
to program via the cloud instead of the Computer IDE.
Starting with simple example programs (blink) it works fine. As soon as I get to a program that requires WiFi and calls for the ESP8266WiFi Library I get this failure. I do not see the LwipIntf.h library being called from the ESP8266WiFi.h library.
I did try to include it myself both "", and <> around it. It says file not found.
Here is the complete error message.

The library should have been included in the 8266 core. Did you try selecting another 8266?
Thanks,
I don't know what replacing the 8266 core means.
Please forgive my inexperience in the modern vernacular. I see many terms I'm not familiar with in this foray into cloud programming.
FYI
In trying to parse the error message, it says multiple libraries were found for ESP8266WiFi.h:

Using library ESP8266WiFi at version 1.0 in folder: /mnt/create-efs/webide/86/ae/86aed964d643f6ae8e8efcd0e94e6a7c:Bill_H/libraries_v2/ESP8266WiFi
Over the years i've uploaded libraries for projects.
I'm wondering is it using something I uploaded at some point rather than the latest one in the cloud library?
Thanks to Idahowalker, ZX80 and juraj for pushing me in the right direction.
You are awesome!!
As they say, A problem precisely described, is already 1/2 solved (or something like that...)
I deleted my custom library ESP8266WiFi.h...............duh
All is good.
