One thing I think is worth noting: GCC 5 represents an ABI break for C++11 http://developerblog.redhat.com/2015/02/05/gcc5-and-the-c11-abi/ Thus, some serious care is needed to avoid compat hazards when using C++11. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
