[ceph-users] ceph 14.2.8 tracing ceph with blking compile error

I want to trace a request in ceph processing in 14.2.8 version. I open the blkin with do_cmake.sh -DWITH_BLKIN=ON, when compile there is a error in below: ../lib/libblkin.a(tp.c.o): undefined reference to symbol 'lttng_probe_register' //lib64/liblttng-ust.so.0: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status make[2]: *** [src/CMakeFiles/ceph-osd.dir/build.make:130: bin/ceph-osd] Error 1 make[1]: *** Waiting for unfinished jobs.......
