ld – Wading through Mac OS X linker hell

Intro

Friend: I tried looking at static linking in Mac OS X and it seems nearly impossible. Take a look at this http://stackoverflow.com/a/3801032

;;; EXTRACT FLAT (PURE) BINARY:

;;;     1a. Take the offset, convert to hex and verify code starts there in the hexdump view of the compiled binary
