Bug #36508
Updated by Brad Hubbard over 5 years ago
Binaries compiled against the 2.6 version of libtcmalloc.so.4 (in this case ceph-osd) have the following undefined symbols. <pre> # nm -D /usr/bin/ceph-osd|egrep '(_ZdaPvm|_ZdlPvm)' U _ZdaPvm U _ZdlPvm </pre> The 2.4 version of libtcmalloc.so.4 (gperftools-libs-2.4-8.el7.x86_64) does not export these symbols. <pre> # nm -D /usr/lib64/libtcmalloc.so.4|egrep '(_ZdaPvm|_ZdlPvm)' # </pre> This leads to errors such as the following at runtime. ceph-osd: symbol lookup error: ceph-osd: undefined symbol: _ZdaPvm Installing gperftools-libs-2.6.1-1.el7.x86_64.rpm resolves the issue. <pre> # nm -D /usr/lib64/libtcmalloc.so.4|egrep '(_ZdaPvm|_ZdlPvm)' 0000000000035dc0 T _ZdaPvm 0000000000035dc0 T _ZdlPvm </pre> This issue is related to http://tracker.ceph.com/issues/35969 which required the 2.6 version at *build* time.
