Hi,
I have a problem with my project, that it throws a linker error while building the project. In Arduino IDE all builds well.
Arduino IDE 1.8.9, Arduino pro micro (Atmega32U4).
Attached is the build output and project.
I hope someone can give a hint, where the problem is.

Thanks

Hello,
no, it got me this error:
Gamepad_Leonardo.ino: 7:25: fatal error: HID-Project.h: No such file or directory
   compilation terminated

An error was encountered during the 'Deep Search' library discovery process.
Build failed for project 'Gamepad_Leonardo'

this should be correct, because the included header file is in this directory.

BUT, you gave me the hint with the 2 different HID libraries. I renamed the HID-library in E:\Arbeit\Arduino\libraries\ to HIDproject and it builds just fine and is functional.
In Arduino IDE it builds also ok with the change.

Thanks for your fast response.

We have looked at this and it seems correct that the build fails. We also see a build failure in the Arduino IDE but slightly different error.


Ccan you please rename the library folder back to HID and then in the Arduino IDE please switch on "File>Preferences>Compile Verbose" and build. Then post the output from the Arduino IDE.

The problem is that many of the .h files in the HID library that you are using contain #include "HID.h", but the library does not contain a "HID.h". The auto discovery of libraries that both the Arduino IDE and Visual Micro use, detects the need for a "HID.h" and throw error when it is either "not found" or "only available in a different incorrect location".

We will update visual micro so that it handles the breakage the same way as the Arduino IDE. At least both IDE's will show the same error which might be less confusing. 

If you have the time, I am keen to see the Arduino IDE build output so we can see why/how it is working for you.

Thanks again for the report.

Interesting thanks. You are using an older Arduino 1.8.9 IDE which I just tried and it worked OK. The more recent Arduino IDE versions (such as 1.8.13) fail.

It seems the older Arduino version, whilst working in this case, it doing something that could cause unexpected results. Taking some source code from "Library Version A" and part source from "Library Version B". 

In this case renaming the folder of the override HID library (as you have done) certainly resolves and in a more reliable manner. This allows both libraries to be used fully.

We will change this behaviour if the Arduino IDE build guidelines officially recognize this way of working but currently we can't find that in the docs.

Will continue to review, thanks for the post.
