--- Comment #23 from Martin Storsjö martin@martin.st --- (In reply to Zebediah Figura from comment #22)
FWIW, the configure script tries first to check for unw_step(), and then tries it again linking to UNWIND_LIBS (which defaults to -lunwind). You've quoted the first check, but both fail in the log, and I'm guessing it's the latter that's supposed to work.
Oh, indeed. For some reason, the second test doesn’t print any executed command in this log:
configure:16618: checking for unw_step in libunwind configure:16645: result: no
In my logs, I see the successful command here.
Does --with-unwind affect this somehow? (I don’t pass that explicitly, I just let it autodetect it.)
