Ned Deily added the comment: Thanks for the report. This warning is currently visible on many/all of the buildbots on all branches. The conflict is caused by the upgrade of the bundled to libexpat to version 2.2.1 (bpo-30694). 2.2.1 introduced a define of _GNU_SOURCE into Modules/expat/xmlparse.c. The definition in xmlparse is simply:
#define _GNU_SOURCE But Python, in pyconfig.h, which ./configure generates from pyconfig.h.in, may already have defined _GNU_SOURCE thusly: #define _GNU_SOURCE 1 pyconfig.h gets included into our copy of Modules/expat/expat_config.h which is included later in xmlparse.c causing the compile warning. The simplest way to avoid the warning is to just change the definition in xmlparse.c to match that in pyconfig.h; the compilers don't complain if the definition is identical. I have now merged that fix into the 3.6 branch so builders of 3.6.2 won't see the warning. I will leave this open for @haypo to review and to handle merging into the other branches affected by bpo-30694 (master, 3.5, 2.7, 3.4, 3.3). ---------- assignee: -> haypo nosy: +haypo stage: -> backport needed type: compile error -> versions: +Python 2.7, Python 3.3, Python 3.4, Python 3.5, Python 3.6 _______________________________________ 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
