    Did you run autogen.sh again just to be sure?

    So I guess you may have figured that out already but that’s not a serious issue, it just means that some conftest.dSYM directory will be left in your tree. See https://lists.gnu.org/archive/html/bug-autoconf/2007-11/msg00017.html …

    What’s the output of glibtool --version and autoconf --version? edit: and autoreconf --version?

    Yess :)

    Yeah, I’ve read some mls, including that you point at, and I agree that’s not a serious issue.

    Hm, these are not the most recent versions but they should be recent enough then… Cirrus CI shows the same issue: https://cirrus-ci.com/task/5325071847784448?command=test#L51

    Can you try removing the directory and see if the error persists?

    Looking at the the (old) Travis logs, I believe this was introduced by #862. Can you confirm this?

    before: https://travis-ci.org/github/bitcoin-core/secp256k1/builds/754093307 after: https://travis-ci.org/github/bitcoin-core/secp256k1/builds/754127317 Make sure to look at “gcc” build (which is Apple’s fake gcc).

    Both packages are installed via Homebrew, btw:

    find . -type d does not list such directories…

    I think 83fb1bcef49b1c12ef349f62d90bfcc83f0f7398 (#700) is the cause of warnings.
