I am installing an ESP8266 on my old Win XP lap top. I put the following http: http://arduino.esp8266.com/stable/package_esp8266com_incex.json into the “Additional Board Manager URLs” of the preferences section of my arduino IDE and clicked on OK. It accepted the entry, but all of my ESP826 based sketches generate multiple errors on compilation.
Here is a comment from a user on the ESP8266: I am having the same problem and, although it may work, I do not believe that putting the ESP8266 libraries in with the regular Arduino libraries is the correct solution.
The ESP8266 libraries have always been placed in a different location altogether, in my case deep within the C:\Users\<username>\AppData\Local\Arduino15 folder.
They have always been found in that location and they can still be found on the computer that I have upgraded to v1.8.9. It is on two new installations that the IDE cannot find them, even with the libraries in the equivalent location and with the same source code.
Sounds like the same problem, but the user provides no solution. Does anyone in this group have an idea what to do?
Hello, you should mess with the libraries manually. The ESP8266 libraries should be installed through the Boards Manager dashboard, otherwise it will be hard to update them and I can’t guess exactly what you’re doing.
After upgrading to Arduino IDE 1.8.9, can you remove the ESP8266 add-on and re-install it?
Usually after upgrading remove/re-installing solves any problems like that.
Thanks for your patience throughout this process!
