Hi, I have cloned ceph from git master branch. I am getting the following errors while build: ENVIRONMENT ---------------------- $ uname -a Linux donjaffer 4.3.0-dev #1 SMP Sun Dec 6 13:56:49 EST 2015 x86_64 x86_64 x86_64 GNU/Linux $ g++ -v Using built-in specs.

[all-recursive] Error 1 shehbaz@donjaffer:~/gsoc/ceph/ceph$ INITIAL DIAGNOSTICS ------------------------------- In src/rgw/rgw_rados.h struct RGWZoneGroup : public RGWSystemMetaObj all pure virtual functions in base class should be overriden in derived class. In RGWSystemMetaObj, the following functions are defined pure virtual: virtual const string& get_pool_name(CephContext *cct) = 0; virtual const string get_default_oid(bool old_format = false) = 0; virtual const string& get_names_oid_prefix() = 0; virtual const string& get_info_oid_prefix(bool old_format = false) = 0; virtual const string& get_predefined_name(CephContext *cct) = 0; All these functions have been declared and overridden in struct RGWZoneGroup: const string& get_pool_name(CephContext *cct); const string get_default_oid(bool old_region_format = false); const string& get_info_oid_prefix(bool old_region_format = false); const string& get_names_oid_prefix(); const string& get_predefined_name(CephContext *cct); I also found a similar report here: http://ceph.predictor.org.pl/rgw_vtable.txt But a solution to the problem is not provided.
