ARDUINO_BOARD symbol build error ESP8266

[fow0ryl]

I'm getting this issue in a fresh install of Sloeber 4.3.1 or nightly build and ESP8266 2.4.2 on manjaro linux.
It looks like #493
After doing some tests I createt a new project with this code

#include "Arduino.h"
#include <ESP8266mDNS.h>

void setup()
{
    MDNS.addService("http", "tcp", 80);
}

void loop()
{
}

First_ thing to do is to remove automaticaly added include of WiFi lib, since there are conflicting definitions "WiFIUDP" to ESP8266WiFi.

During compile I get this error:

Then I found #960 and I removed the ESP8266 platform and reinstalled it.
But nothing changed.

At least I changed the defines in ESP8266mDNS.h and everthing went ok.

#define ARDUINO_BOARD "ESP8266_WEMOS_D1MINI"

How to do it the right way?

I am facing the same issue on Linux Mint 19 with a fresh install of plugin versions 4.2.0, 4.3.0 and 4.3.1.
I tried reinstalling the esp8266 platform as suggested in #960 with no effect.

Minimal sketch that does not compile:

#include "Arduino.h"
#include "ESP8266mDNS.h"

void setup(){}
void loop(){}

This is probably related to using " to get strings in your code which is a bad idea as " is used to handle spaces. Like #1028
Modifying the file ../sloeber/arduinoPlugin/packages/esp8266/hardware/esp8266/2.4.2/libraries/ESP8266mDNS/ESP8266mDNS.cpp
.... addServiceTxt("arduino", "tcp", "board", ARDUINO_BOARD); ...

to

....
#define VAL(str) #str
#define TOSTRING(str) VAL(str)
....
addServiceTxt("arduino", "tcp", "board", TOSTRING(ARDUINO_BOARD));

should do the trick

I can't call this a bug as it (probably works in Arduino IDE) but wanting to make a space, quote and OS safe command line is very challenging.
As there is a way to avoid having to use a quote safe way I would advice to do so.
Unfortunately it is not my call

[fow0ryl]

I can confirm, that the workaround is working as expected.

Thank your very much. You made a newbie very happy.
(I'm on the way from atmega32 & Windows & Atmel-Studio to linux & arduino & sloeber & ESP right now....)

Thanks for the feedback
I'm closing this as a duplicate of #1028
