Project: https://github.com/mstrens/grbl_controller_esp32
Arduino: 1.8.10
Additional Libraries: SdFat (SdFat_-_Adafruit_Fork version 1.2.1)
All other libraries  in the project, in the TFT_eSPI_ms folder.


Currently we are trying to replicate this but cannot get as far in the compilation process.

Can you attach the output from the Arduino IDE with the verbose compilation enabled so we can investigate further?

If you can confirm any other alterations made to this project or libraries (or supply as a ZIP) it would be help us recreate this issue.

Arduino 1.8.10

Thanks for the report. This is resolved in Visual Micro 1909.26 and is due to the fact that Arduino IDE 1.8.10 no longer provides Ide\Hardware\Platform.txt for default deep library search settings.

The latest version of Visual Micro is available here but will shortly be published to the Microsoft Gallery

Your project has a lot of source code that is not for arduino. When you opened the project for the first time visual micro added the sources to the project in visual studio by mistake.

An arduino project should have source code only in main project folder and in folders below a folder called \src.

The compile errors are in NON arduino sources. This project has only a handful of arduino source code in the project folder.

Please right click and remove/exclude all folders from below the project leaving just the project sources.

The it will build ok. Arduino is ignoring all the sources in the sub folders but because they have veen included in the VS project Visual Micro is trying to compile them.

To easily see the folders to remove click the small icon above the solution explorer called "Show all files". Then right click "Exclude" all folders.

This image shows the VALID files from the project folder only.

Visual Micro will be updated to ignore all invalid sources when opening a project. For example, the TFT_eSPI_Button sources should NOT be compiled, they are not for Arduino.

Hello
Tim
I understood you.
Such a decision is inconvenient for work.
I will wait when you fix it in Visual micro.
Please let me know how this will be done.
Maybe you can add in the settings the ability to compile strictly, exactly according to the rules
Arduino ide.
That would be a good decision.
If of course, it is possible.

Tim
I understood.
But you can fix it so that files are not added by accident.
Like this, does the native Arduino Ide?
According to her rules!

Tim
Sorry, I'm at work.
The project is located at home.
Result later

I found there is already an option to control if all folders are discovered or just the arduino compatible folders.

Tools>Options>Compile all folders

The default was true but should have been false. In the 1909.27 release the default has been changed to false. This means that creating a new project with the grbl code will now compile 1st attempt.

Sorry the link is repaired now.

You are right the property was not exposed to the UI. 1909.27.1 is available in the forum releases that exposes the property

Tools>Options>Visual Micro>Allow Code in Any Subfolder

It is not recommended for use and might cause a lot of issues in the future. For example if Arduino add support for a local "Libraries" folder it is possible that some people will have created their own folder called Libraries and that would have to be ignored and compiled as real libraries (not part of the project code). 

Highly recommend Arduino IDE compatibility using only the following folder structure:-

Project Folder
Project Folder\src
Project Folder\src\......
