You’ll want to provide a more literal transcript, including a literal transcript of the error. A summary of a message you don’t quite understand is unlikely to result in a clear diagnosis. 
Are these the documents you are following?
```
cut and paste the EXACT ERRORS you are seeing
in between two lines that contain exactly only
three single back quote characters each
```
This way we see them without interpretation and without formatting.
Yeah a copy and paste of the error codes, or a screenshot or whatever would be helpful. Also if we’re really running to problems post up your Marlin folder and I can download it and try and compile and see if I run into the same errors. If I don’t get errors compiling then it’s probably dependencies that are installed. If I do get errors then it’s probably in the syntax somewhere.
I have resolved most of the errors now (your correct response - missing dependencies), but I don’t yet understand this last one, not sure what I am missing, I don’t know the entry to point to a specific disk? I am assuming it is looking for the SD card, which I have in a usb port, or is it looking for my BTT oard and it’s usb port?

Unable to find destination disk (Autodetect Error)
Please select it in platformio.ini using the upload_port keyword (Upload options — PlatformIO 5.2.0a4 documentation) or copy the firmware (.pio/build/LPC1769/firmware.bin) manually to the appropriate disk
Literally, it means copy the file .pio/build/LPC1769/firmware.bin to the root directory of the SD card
Then when you reset (or cycle power) with the card inserted it will update the firmware on the board.
Also even though that is the only error in the terminal, there is no firmware.bin in the directory specified.
I use the terminal instead of the platformio gui, so I’m using platformio run to build Marlin. I don’t have the board connected when I build. What have you set default_envs to in your platformio.ini file?
default_envs = LPC1769
I think @Eclsnowman is right; easier to debug if you zip up your current directory and one of us tries to build. 
Also, as I said before, when showing errors:
```
cut and paste the EXACT ERRORS you are seeing
in between two lines that contain exactly only
three single back quote characters each
```I thought I did that, but not the three single back quotes.

Therefore, this line from your build log looks like it is relevant:
*** [Marlin\src\HAL\LPC1768\DebugMonitor.cpp] D:\Downloads\Marlin-2.0.vs\Marlin-2.0.x\.pio\build\LPC1769\.sconsign37.db.dblite: No such file or directory
@Eclsnowman want to try on Windows and see whether you can reproduce this problem?
I did not ever see that message. I’ll research that now. Thanks for giving that a run!
I may be missing something, that file does not have today’s date on it, so I am not sure that is reflecting tonight’s build attempt?
I see No such file or directory in your build log so it surprises me that you found an old file by that name. I wonder if you could just delete the whole .pio directory and try again?
What I’ll do later today once I get some free time is try and set up a clean Marlin that I can get to compile. Would you be able to confirm all the hardware you have: steppers, drivers, LCD, travel limits from before, etc:
That way I can go through and confirm your config against one I’ve set up in the past for my skr v1.3 Eustathios and just make the changes for your setup.
I have most of the details in the configuration.h file in the zip. I transferred the setting from my smoothie config file. I am really trying to learn the environment of visual studio code and the marlin at the same time, probably not a great combination. But my thought was to get a solid compile and then add additional features in…Once I get a successful compile, I have a bltouch to add, and I wanted to go without the X and y End stops.
Okay sounds good, I’ll take a look later tonight. I’m going to get some work done around the house while it’s nice out.
Okay, . I cleaned out all the marlin, platform io and Visual Studio code files from my computer.
I reloaded everything and did a simple compile for the mega. Successful.
I followed the marlin page on identifying and updating configuration.h for the BTT SKR 1.4 Turbo board. Made the change to platformio.ini to reflect the board. Successful.
I am going back to make the customization for my Herculien. Looks like I just did not get a clean install in the beginning.
Thanks to you both for looking at this. I’ll hopefully report back a successful build after church today.
One more variation on “Hello, IT, have you tried turning it off and back on again?” 
Glad to hear you got it sorted out.
