Using Eclipse Neon.3, Linux Mint 18, Arduino C++ Tools

Most projects work with few problems. Great work Doug, thank you.

In essence, when I started a new project (no code at all beyond starter template) and included just the ESP8266mDNS and ESP8266WiFi libs the build errored:

/home/rob/.arduinocdt/packages/esp8266/hardware/esp8266/2.3.0/libraries/ESP8266mDNS/ESP8266mDNS.cpp: In member function 'void MDNSResponder::enableArduino(uint16_t, bool)':
<command-line>:0:15: error: 'ESP8266_WEMOS_D1MINI' was not declared in this scope
ESP8266mDNS.cpp:841:44: note: in expansion of macro 'ARDUINO_BOARD'
addServiceTxt("arduino", "tcp", "board", ARDUINO_BOARD);

I fixed it manually: the build line included:
... xtensa-lx106-elf-g++ ... -DARDUINO_BOARD="ESP8266_WEMOS_D1MINI" ...
I changed it to:
... xtensa-lx106-elf-g++ ... -DARDUINO_BOARD=\"ESP8266_WEMOS_D1MINI\" ... (note extra backslashes in front of quotes)

I'm guessing platform.txt needs an extra 2 backslashes before quotes in the appropriate places? I haven't changed it as it has worked fine until ESP8266mDNS and I know nothing of Arduino infrastructure.
NOTE: the ESP8266mDNS library was a nuisance - it didn't download with a file and didn't show up in the library list until I fudged one.

Other, non-important, observations:
Arduino Downloads Manager : Seems to give lots of "Unhandled event loop exception" from cdt. Mainly works OK though I think.
Flashing failed until I made myself a member of dialout group.
Normal CDT stuff like Indexing, refactoring etc. work brilliantly. Very big thanks again Doug. (Great for an Arduino newbie like me.)
Ability to exclude files from build is not implemented it seems?
I assume the only way of getting rid of the admittedly very friendly Arduino toolbar is a separate install of Eclipse?

I'm using Eclipse Photo Release 4.8.0 with Eclipse C++ IDE for Arduino I am extremely new to Eclipse and just playing with Arduino boards for fun.
I managed to fix the other issue you mentioned regarding the file. I cannot find the line that you mention fixing about. I'm about to give up and go back to the Arduino IDE--please give some further info for fixing this issue. Also, am I correct that both of these issues should be reported to the maintainer of the ESP8266mDNS libarary for a long term fix?

Guys, you got to create a file on

.arduinocdt\packages\esp8266\hardware\esp8266\*YOUR VERSION HERE*\libraries\ESP8266mDNS

With the following contents

Only then you can add the library on your project and proceed.
Looks like they forgot to add them (?)
