As I'm new to MCUXpresso, I found this compiler behaviour rather disconcerting so thought to throw it to the community for reassurance.
I have been using a FRDM-KW41Z board and have not tested to see if this applies to other boards.
I noticed these two links are always included (in paths and symbols within includes in C/C++ general properties) in new projects or if I import an SDK project.
I was porting code from another project and editing this code in a new project and kept noticing that these two links disappeared after a while and could not fathom why.
So I carefully reconstructed and discovered that these two links disappear from my project as soon as I run a build and it fails.
So I am wondering if this normal behaviour?
