Hi, I was planning to report this for long but keep on forgetting. Basically, if I enable jemalloc on ceph build , it is failing for me with the following error. Makefile:16236: recipe for target 'ceph_objectstore_bench' failed make[3]: *** [ceph_objectstore_bench] Error 1 rocksdb/librocksdb.a(db_impl.o): In function `DumpMallocStats': /root/ceph-master/src/rocksdb/db/db_impl.cc:595: undefined reference to `malloc_stats_print' rocksdb/librocksdb.a(db_impl.o): In function `DumpMallocStats': /root/ceph-master/src/rocksdb/db/db_impl.cc:595: undefined reference to `malloc_stats_print' collect2: error: ld returned 1 exit status Makefile:16792: recipe for target 'ceph_test_objectstore' failed make[3]: *** [ceph_test_objectstore] Error 1 collect2: error: ld returned 1 exit status Makefile:16359: recipe for target 'ceph_smalliobenchfs' failed make[3]: *** [ceph_smalliobenchfs] Error 1 rocksdb/librocksdb.a(db_impl.o): In function `DumpMallocStats': /root/ceph-master/src/rocksdb/db/db_impl.cc:595: undefined reference to `malloc_stats_print' I am commenting out the following line (and do a make clean on rocksdb folder) in src/rocksdb/db/db_impl.cc to make build go through. malloc_stats_print(GetJemallocStatus, &mstat, ""); Thanks & Regards Somnath PLEASE NOTE: The information contained in this electronic mail message is intended only for the use of the designated recipient(s) named above.
