So I've been debugging a build issue against python3. Specifically changes made by https://www.python.org/dev/peps/pep-0539/
https://github.com/vim/vim/blob/master/src/if_python3.c lines 38-40 appear to be the culprit. It's weird but it appears as if once _POSIX_THREADS has been undefined, it can not be defined again. I even included unistd.h manually afterwards to test. I'm wondering if perhaps unistd.h is being included earlier in the stack, so it gets detected as a duplicate and never gets included again thus _POSIX_THREADS remains in an undef state. Is there a specific reason for the undef in the first place? Based on the comment on line 37, it doesn't appear to be necessary. I'm building on macOS using Apple LLVM version 9.1.0 (clang-902.0.31). I also tried with gcc version 7.3.0 (Homebrew GCC 7.3.0) in case it was a compiler issue. -- -- You received this message from the "vim_dev" maillist. Do not top-post!
