Problems with Marlin 2.0.3 compiling - Mega2560 error SOLVED Myself

Hi,
Working on updating home built DIY Mendel Prusa i3 clone with Marlin 2.0.3 and Ramps 1.4 controller.

I need some technical help here. On my desktop PC I configured my newly downloaded copy of Marlin 2.0.3 today - I had cleared my PC of every Marlin file before installing the new version. I opened Marlin.ino in a newly installed Arduino IDE version 1.8.11. After configuring each item which I changed, I verified the firmware so that I could isolate any problems individually as I went along. On the final verification the firmware compiled without error (I did have a problem with the RepRapDiscount Full Graphical controller initially but sorted that).

I then took the configured firmware loaded onto a thumb drive and opened it on the PC attached to my printer. When I verified it I was surprised to get an error message reporting problems with linking to the Arduino Mega 2560. Thinking that I might be missing some files on that PC in order to checkI returned to my study PC (printer is in detached garage) and was surprised to get the same error message despite it verifying correctly earlier.

This is the message I got after it had verified the firmware and when Arduino was linking it together.:

The top 5 lines were all on one but I separated them for clarity. I have investigated the files indicated in the error message but am not a programmer and can't see where the problem is. The mystifying thing is that it verified on my study PC at first but came up with the error a second time I tried verifying it. I have attached a zipped copy of my configuration.h for possible testing.

Here's hoping that some good Samaritan takes pity on a tyro and I would be glad of any help and advice as my poor hair is disappearing as I tear it out.

Solved elsewhere

Hello Terry, I have that same problem. How was it solved?
Thanks.

I suspect they only extracted the some files and not all files from the zip archive.

I suspect they only extracted the some files and not all files from the zip archive.

I downloaded the release version zip file from Marlinfw.org. The standard version without all of the extras and not the LITE either.
I did an "Extract here" which would have extracted all of the files.
Did an install of Martin and got that same error as Terry D.
All of this on a Raspberry Pi 2 Model B. With a 32Gb SD card.

Terry's job is apparently on an MS Windows box.

I also tried this install on my Win10 box and it compiled and uploaded to an Arduino Mega 2560 Rev 3 just fine. No errors.

So I don't think it is a problem with unzipped files.
