They're trying to compile Marlin. Marlin is a popular 3D printer firmware that's written as an Arduino sketch.Evidently they have resolved the library installation problem and are now dealing with another issue, which is likely caused by an incorrect configuration. Marlin has a file Configuration.h and another Configuration_adv.h which contain a ton of #define directives used to configure the firmware for the specific 3D printer it will be used on. Some of these #defines can simply be commented/uncommented to turn the feature on/off, others have a value that can be adjusted.
There are multiple versions available for download from that link. Which one did you download? Also, it's a 21 page thread. Likely any problem you're having has already been discussed there. Did you search through the thread for the error you're encountering?
I was trying to user the one for the r1 plus. Thats the one that is supposed to allow me to mesh level my bed so that it provides more consistent prints. Yes I searched the thread but I only skimmed through the pages looking for the error I'm having. I'll reach out the the vendor tomorrow to see if they can help me a little more on getting what I need.
