Dear Bug Submitter, This bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? I am setting the status to NEEDSINFO pending your response, please change the Status back to REPORTED when you respond. Thank you for helping us make KDE software even better for everyone! Dear Bug Submitter, This is a reminder that this bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? This bug will be moved back to REPORTED Status for manual review later, which may take a while. If you are able to, please lend us a hand.

Created attachment 51558 [details] Workaround for this issue for Solaris builds. Version: unspecified (using KDE 4.5.1) OS: Solaris Solaris KDE builds (4.5.1 now) typically report a number of kWarnings like: kded(3718)/kdeui (KIconLoader) /export/home/kdebuild/packages/BUILD/KDElibs-4.5.1/i386/kdelibs-4.5.1/kdecore/util/kshareddatacache.cpp:937: Failed to establish shared memory mapping, will fallback to private memory -- memory usage will increase This is caused by kshareddatacache.cpp:43-46 (in current trunk): 43 // Mac OS X, for all its POSIX compliance, does not support timeouts on its mutexes, which 44 // is kind of a disaster for cross-process support. So, disable support for shared memory 45 // and add a wrapper implementation. 46 #if !defined(_POSIX_TIMEOUTS) || !defined(_POSIX_THREADS) || (_POSIX_TIMEOUTS < 200112L) || (_POSIX_THREADS < 200112L) On [Open]Solaris we use -D_XPG5 with C++ code and Solaris unistd.h defines _POSIX_THREADS with _XPG5 to 1, not to 200112L as with _XPG6 (which is not recommended for C++ code). It would be good to enclose the above test to something like #ifdef MACOSX or apply the attached patch. Reproducible: Always
