Second iteration. Brevity. Removed historical information (that is what the revision history is for)—the question should be as if it was written right now; see e.g. <https://meta.stackexchange.com/a/131011> (near "Changelogs").

EDIT1: I I tested some more, and the problem is as follows (not what I originally stated above):

What happens whenWhen I try to build is that, I get a 'undefined reference' at the last line, meaning that when I use constants it is fine, but when I pass variables to the sinsin functions it will not link. I also tested many of the other math functionfunctions, and I’ll get the exact same linker issue. As soon as I pass a variable to a math function, I can not link any more. Any ideas?

Active reading [<https://en.wiktionary.org/wiki/nonreentrant#Adjective> <https://en.wikipedia.org/wiki/Sentence_clause_structure#Run-on_sentences>]. Tried to make it clearer what part of the title was literal. Removed unnecessary formatting (use view "Side-by-side Markdown" to compare).
