I narrowed it down, and if I take out the use of any regex then it will link. I can leave in the #include <regex> line, but if I have any line that actually does a regex_search or a regex_replace, then I get the following error output when I compile and link (with my compile line shown first):

I don’t know the answer but I Googled the error message and found this post; does that help?
I’d also ask if you really need to use gcc. Could you use clang instead?
