Scope Error (Read 6335 times)

	I have several projects using visual micro with VS2017. All of a sudden I am getting scope errors. It is not a missing closing } or something like that. It is with all of my projects. It is occurring with code that was saved and working perfectly. I am using ESP8266 and I am using the following libraries, #include <Scheduler.h> #include <Task.h> #include <FS.h> I have always had methods outside of the Tasks and there was never an issue. Please see the attached images. I understand I can move the methods inside each task but two tasks use the same methods and I am hoping to not duplicate the functions in every task. Any help or suggestions would be greatly appreciated. Thank you.

	Try the latest update it has a minor fix. If you have continue issues please follow the guide in yellow above so that we can see the real compiler output.

	Thanks for the example sent via email, its an impressive arduino sketch. Would it be possible to also send us your libraries folder (zipped) so we definitely have all the right code to replicate with?

	Hello, Thank you for the reply. Generate prototypes has always been set to true to my knowledge. Everything has worked perfectly for a very long time. Yesterday I went to compile and have not been able to successfully build since. Sadly adding the board.txt to the project with vm.ctags=false does not help a successful compile. I have attached the output log. The problem I am having only seems to be specifically when compiling for the board "Generic ESP8266" I have some sketches for WEMOS D1 R1 that build ok. They use similar functions that are not directly in the task and they do not get the out of scope error. I only have build/compile issues with ESP8266 and ESP32. Thank you for your time.

	Hello, Folder is quite large and I am getting some permission errors trying to zip. I am sending files with we transfer. Hope that is okay, It is slow but it will contain the exact libraries I am using. You will get email once file upload is complete. Thanks again.

	Oooops!! I changed the path to the libraries folder. I don't need all your sketch book folders. Yes you can also give urls for any libs you have downloaded or if they are in library manager their names and author name.

	I understand. The libraries folder is almost 200 mb. It does not contain the sketehes. Just the libraries. I am using esp8266 core v2.3.0 #include <KMPDinoWiFiESP.h> #include <KMPCommon.h> https://github.com/kmpelectronics/Arduino #include <ArduinoJson.h> ArduinoJson Version 5.13.1 by Benoit Blanchon #include <Task.h> #include <FS.h> #include <Scheduler.h> https://github.com/nrwiersma/ESP8266Scheduler #include <PubSubClient.h> PubSubClient v2.6.0 by Nick O'Leary #include <ModbusMaster.h> ModbusMaster V2.0.1 by Doc Walker #include "ESPAsyncTCP.h" https://github.com/me-no-dev/ESPAsyncTCP #include <ESP8266httpUpdate.h> https://github.com/esp8266/Arduino/tree/master/libraries/ESP8266httpUpdate #include <ESP8266Ping.h> https://www.arduinolibraries.info/libraries/esp8266-ping https://github.com/esp8266/Arduino/tree/master/libraries/ESP8266WiFi I will try to provide more information that may be helpful later on. Thanks again,
