Hmmmm, a blast from the past?… :-) One of first KDE libs bugs I noticed on Apple OS X was: https://bugs.kde.org/show_bug.cgi?id=307652 KSharedDataCache not working on Apple OS X 10.7.4 (Lion) Reported 2012-10-01 Michael Pyne (KSharedDataCache author) was very helpful, but of course he did not have a Mac to test on and I did not have the ability back then to build test versions of kdelibs. It bubbled along for a year or two and then the bug stopped happening in mid-2014, so we closed the Bugzilla report. Mysterious. Re your issue, René, there is just the one use of that POSIX macro in KDE: http://lxr.kde.org/search?_filestring=&_string=_POSIX_THREAD_PROCESS_SHARED&_casesensitive=1 Also see the following pages on KDE's repository browser: https://projects.kde.org/projects/kde/kdelibs/repository/show/kdecore/util?rev=Active%2FTwo https://projects.kde.org/projects/kde/kdelibs/repository/changes/kdecore/util/kshareddatacache_p.h?rev=Active%2FTwo https://projects.kde.org/projects/kde/kdelibs/repository/diff/kdecore/util/kshareddatacache_p.h?rev=a33bbd7cb7d8863e46af066bb447f80fe601ca98&rev_to=15d04d6ea7cc45f70bfbd3e41b3cc4e6b15e367a The "&& !defined(__APPLE__)" string was added on 2011-07-31, a year or so before my bug report (see above), which answers your question about where it comes from, but it cannot be what fixed the bug... Weird. Cheers, Ian W. _______________________________________________ macports-dev mailing list macports-dev@lists.macosforge.org https://lists.macosforge.org/mailman/listinfo/macports-dev
