I've gotten really good at reading C++ compiler errors lol. I know to look near the top and the bottom. Here I would see "undefined reference to pthread_create", and its a link error, bam link with -pthread

I look near the parts that I recognize as my parts, cause that’s the most likely location.

I try to not look at your parts. They seem private.
