Assuming you get past that, though, I would expect you to hit the #20557 bug anyway. Starting with luminous we've recommended users stop using jemalloc because the switch to AsyncMessenger wipes away the benefit users were seeing in jewel; tcmalloc and jemalloc now perform about the same (when jemalloc isn't crashing :). sage > I have merged the commit below but failed to compile the code, > > https://github.com/ceph/ceph/pull/18010 > https://github.com/ceph/ceph/pull/18010 > > The screen shows : > src/rocksdb/db/db_impl.cc:401 undefined reference to 'malloc_stats_print' > Make[3] : [ceph_test_keyvaluedb] ERROR 1 > src/rocksdb/db/db_impl.cc:401 undefined reference to 'malloc_stats_print' > Make[3] : [ceph_osdmap_tool] ERROR 1 > src/rocksdb/db/db_impl.cc:401 undefined reference to 'malloc_stats_print' > Make[3] : [ceph_kvstore_tool] ERROR 1 > > Then I find some related commit which merged in Lumious： > cmake: should link against ${ALLOC_LIBS} > https://github.com/ceph/ceph/pull/11978/files > > But this commit did not resolve my problem, there errors still exists. > > But when I compile 10.2.11 , no errors show, it's very surprising.
