New submission from Segev Finer: This is caused by _GNU_SOURCE being defined here: https://github.com/python/cpython/blob/c08177a1ccad2ed0d50898c2731b518c631aed14/configure.ac#L124, But also getting defined by AC_USE_SYSTEM_EXTENSIONS (https://github.com/python/cpython/blob/c08177a1ccad2ed0d50898c2731b518c631aed14/configure.ac#L906).
AC_USE_SYSTEM_EXTENSIONS does use an #ifndef but Python's AC_DEFINE seems to be getting order after it. ---------- components: Build messages: 297238 nosy: Segev Finer priority: normal severity: normal status: open title: ./pyconfig.h:1438:0: warning: "_GNU_SOURCE" redefined [enabled by default] type: compile error versions: Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30797> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
