On an ubuntu trusty system, * I installed v9.1.0 and could bring up a single node cluster with it. * I did a git checkout of v9.1.0, followed by ./autogen.sh; ./configure; make Then when I try to run for example the rados I just built using "./src/.libs/rados -v" I get ./src/.libs/rados: symbol lookup error: ./src/.libs/rados: undefined symbol: _ZN8librados20ObjectWriteOperation9copy_fromERKSsRKNS_5IoCtxEmj which decodes to librados::ObjectWriteOperation::copy_from(std::string const&, librados::IoCtx const&, unsigned long, unsigned int) Is there any reason why this symbol should not be resolved by the installed libraries of v9.1.0? -- Tom Deneau -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
