This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

The problem seems to be with the contents of your C:\Users\Matte\Documents\Arduino\libraries\ESP8266WiFi\ folder.

It seems that the compiler is using this, rather than the files from the ESP core.

I’d suggest that you delete it, or move it somewhere out of the way.

Pete.

3

Excuse me Pete, but which folder are you referring to? The ESP8266WiFi contains 2 folders: examples and src. And the src folder has an “include” folder containing some h. files.

4

Everything.

Pete.

5

I’ve moved the folders in the ESP8266WiFi but it says now that No such filre or directory ESP8266Wifi.h Can you clarify what should be the only files(.h .cpp .txt) included in the ESP8266WiFi folder, or if is the whole folder at all needed?

6

If you have the ESP8266 core installed (which you need to provide ESP8266 functionality) then when you compile the sketch it should use the ESP8266.h file from the ESP8266 core.

With verbose compiler messages turned-on, and v3.0.2 of the ESP8266 core installed, I see this…

and near the end of the compilation this:

Using library ESP8266WiFi at version 1.0 in folder: C:\Users\Pete Knight\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\3.0.2\libraries\ESP8266WiFi

As you can see, the path for these files is the core files.

If you delete the entire ESP8266WiFi folder and all of its contents from C:\Users\Matte\Documents\Arduino\libraries\ then re-install the latest ESP8266 core (Tools > Board > Boards Manager - search for ESP8266 and install version 3.0.2) then the compiler should find the correct file.

Pete.
