Eric N. Vander Weele <eri...@gmail.com> added the comment: I discovered that `Makefile.in.pre` injects include paths for building the interpreter, itself, which should probably not be passed along via distutils for building C/C++ extensions 😕.
https://github.com/python/cpython/blob/842a2f07f2f08a935ef470bfdaeef40f87490cfc/Makefile.pre.in#L101 It seems like more investigation is required in determining the purpose of `CPPFLAGS` with respect to building the interpreter and if `distutils` should be passing along at`./configure` time of the interpreter. For now, specifying include paths via `CFLAGS` will still suffice until the scope of `CPPFLAGS` is better defined. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33990> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
