Error compiling basic homie sample

[rossdargan]

I'm using the following:

Arduino IDE 1.6.6
ESP8266 board 2.1.0
ArduinoJson 5.0.7
Bounce2 0.2.0
PubSubClient 2.4.0
Homie 1.3.0

My board is a NodeMCU V0.9

I can flash other programs to the board fine using the above.

I have tried the following

#include <Homie.h>
void setup() {
  Homie.setup();
}

void loop() {
  Homie.loop();
}

I also tried adding the following includes at the top as I didn't know if they were required

#include <ArduinoJson.h>
#include <PubSubClient.h>
#include <Bounce2.h>

I get the following error when I try and compile the app

Sorry it's probably something really obvious, I just can't figure it out!

Indeed: https://github.com/marvinroger/homie-esp8266/blob/master/docs/2.-Getting-started.md#1a-for-the-arduino-ide

You need PubSubClient >= 2.5.0 :)

[rossdargan]

Doh, that was it (2.4.0 is the latest you will get from the arduino manage library stuff)

@rossdargan Arduino IDE 1.6.8 has what you need: PubSubClient 2.6.0
