For context: My first post on this forum, first ide besides Arduino, first time using debug hardware. No answer or question is too obvious for me to potentially miss it, and please educate me if I am violating forum etiquette.

I have an Arduino Due and a J-link Edu mini and have successfully initiated communication through J-link Commander (Jlink.exe) using the SWD on a Ubuntu 20.04 Linux pc. I am now trying to build the example Arduino Due bare metal debugging program here (screenshot attached):

wiki.segger.com/images/a/a4/Arudino_Due_Hello_World.zip

I have extracted the file but can find no clear instruction on where to place it, through the ide user guide or search engines (surely this is my failure).
I selected the "Open Solution" option in the File menu and selected the

"Arudino_Due_Hello_World.emProject" file

(sic) which seemed to import (wrong term?) the files but when I attempted to build the project I received this error:

"unknown type name error '__printf_tag_ptr'"

Screenshots attached.

I'm embarrassed to be asking such basic questions but there is noticeably less user info and guides available for Embedded Studio than Arduino. Also, I promise my blood pressure spiked to unhealthy levels multiple times before asking the forum but the increased functionality of true debugging hardware is too powerful and intriguing to let go. Thanks for any help and sorry for any annoyances. Please advise me on any ettiquette changes required.

Yes, I believe it did build out of the box this time. I will include a screen shot at the bottom in case my inexperience with Embedded Studio has me misled.

And a question about the Arduino Due page mentioned above on the Segger wiki. Under the requirements list it is stated that a 10-pin connector is needed, while the J-Link Commander screenshot in the article shows the connection method as SWD. Is SWD functional in this case? It is my preferred interface by far.

Finally should I start a new thread if problems occur with loading and/or debugging the program onto the Due? Or should I ask in this thread?

Thank you for the quick reply to the previous post.
