Category: Installation Group: Python 2.3 Status: Closed Resolution: Invalid Priority: 5 Private: No Submitted By: Matthias Klose (doko) Assigned to: Nobody/Anonymous (nobody) Summary: pyconfig.h defines _POSIX_C_SOURCE, conflicting with feature Initial Comment: [forwarded from http://bugs.debian.org/206805] the installed include/python2.3/pyconfig.h defines _POSIX_C_SOURCE, which leaks down into packages built against python-2.3. AFAIK, _POSIX_C_SOURCE is reserved for use by the C library, and is of course defined in /usr/include/features.h. Example excerpt from a build log: In file included from /usr/include/python2.3/Python.h:8, from sg_config.h:22, from sg.h:29, from sg_project_autosave.c:26: /usr/include/python2.3/pyconfig.h:844:1: Warnung: "_POSIX_C_SOURCE" redefined In file included from /usr/include/stdlib.h:25, from sg_project_autosave.c:19: /usr/include/features.h:171:1: Warnung: this is the location of the previous definition ---------------------------------------------------------------------- >Comment By: Matthias Klose (doko) Date: 2007-01-11 10:13 Message: Logged In: YES user_id=60903 Originator: YES 8. For the C programming language, shall define _POSIX_C_SOURCE to be 200112L before any header is included _POSIX_C_SOURCE should be defined "before any header is included". That phrase was taken from the following comments: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=793764&group_id=5470 It's described at: Single Unix Specification 3: "2.2.1 Strictly Conforming POSIX Application" 8. ---------------------------------------------------------------------- Comment By: Martin v. Löwis (loewis) Date: 2003-08-31 19:26 Message: Logged In: YES user_id=21627 _POSIX_C_SOURCE is not reserved for the C library, but for the application, see http://www.opengroup.org/onlinepubs/007904975/basedefs/xbd_chap02.html (section "Strictly Conforming POSIX Application") A conforming POSIX application *must* define _POSIX_C_SOURCE, so if your C library also defines it, it is a bug in the C library. Most likely, the author failed to include Python.h before other system headers, as required per http://www.python.org/doc/current/api/includes.html ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=793764&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
