ESP8266mDNS.h declaration before esp8266-google-home-notifier.h causes compilation errors

[debsahu]

Using git version of arduino-esp8266, Arduino IDE 1.8.5, Windows 10 x64.

Adding #include <ESP8266mDNS.h> before #include <esp8266-google-home-notifier.h> causes compilation issues. I'm guessing the internal ESP8266mDNS.h is interfering with this.

C:\Users\xxxx\Dropbox\Arduino\libraries\arduino_244670\src\esp8266-google-home-notifier.cpp: In member function 'boolean GoogleHomeNotifier::device(const char*, const char*, int)':

C:\Users\xxxx\Dropbox\Arduino\libraries\arduino_244670\src\esp8266-google-home-notifier.cpp:44:33: error: 'class MDNSResponder' has no member named 'txt'

           if (strcmp(name, MDNS.txt(i, "fn").c_str()) == 0) {

                                 ^

Thanks @debsahu and sorry for late reply.

This library declares MDNS in internal ESP8266mDNS.h.
So you need to add #include <esp8266-google-home-notifier.h> before #include <ESP8266mDNS.h> and some header files which includes it.

This internal ESP8266mDNS.h will be included in Arduino core for ESP8266 WiFi chip 2.5.0, then I will remove the internal one from this library.

I understand, thanks for the awesome library!

I heard that google is going to monetize translation service, dont know how it will effect tinkerers like us!

Hi, I followed the trail to here because I was getting the same or related compile errors.

In the setup instructions it says:
"use Arduino Core for ESP8266 2.5.0, which will merge ESP8266mDNS.cpp/.h, or later."

However, that pull request doesn't appear to have been merged in as esp8266 completely changed the mDNS implemenation.

"Closing in favor of #5384 ."
which was then:
"closing in favour of #5442"

and that's what seems to have ended up in 2.5.0

I haven't quite sorted out where the txt() function ended up, if they included one.

Not work with Arduino IDE 1.8.8.
Worked very well with older versions. Can GCC4.4 be the cause?

Etc...

Could you please try esp8266 core 2.4.x?
This library doesn't work with 2.5.0 or later.

Please refer to #14 .

And open new issue in order to notify me if you have problems yet.

Hello, I set up version 2.4.2 and the compilation goes smoothly. I wanted to recompile my program because the phrases sent were no longer heard by googlehome. I'm afraid Google is deleting its APIs as it has been saying lately. I will try, and I'll let you know as soon as possible. Thanks for your help.
