Hello I am doing an application on ESP8266 Wemos d1 r1 using Platformio. When I compile, I get the following error message. When I compile the same code with Arduino ide, it does not give an error. What could be the mistake. #include <Arduino.h> #include <ESP8266WiFi.h> #include <ESP8266WebServer…

Move the files Switch.cpp and UpnpBroadcastResponder.cpp to the src folder. Then it should work – or you should at least make progress. include and src belong togehter. lib should only contain directories with further subdirectories.
