Hello Alex, I reinstalled lttng-tools-2.1.0 and compiled Mariadb with lttng-ust.2.1.2(now they work together) The following is related to lttng-tools-2.1.0 in /usr/local/lib after I reinstalled it.
-rw-r--r-- 1 root root 1018130 May 18 13:50 liblttng-ctl.a -rwxr-xr-x 1 root root 1035 May 18 13:50 liblttng-ctl.la lrwxrwxrwx 1 root root 21 May 18 13:50 liblttng-ctl.so -> liblttng-ctl.so.0.0.0 lrwxrwxrwx 1 root root 21 May 18 13:50 liblttng-ctl.so.0 -> liblttng-ctl.so.0.0.0 -rwxr-xr-x 1 root root 491876 May 18 13:50 liblttng-ctl.so.0.0.0 But it reports the same error as before. If it is a compatibility problem, why my instrumented J9 VM with lttng-ust.2.1.2 has no this errors?

Anything I > missed? Mathieu was talking about 2.0 vs 2.1, not 0.x vs 2.x. If you compiled your application with lttng-ust 2.1, make sure you use lttng-tools 2.1 to trace it. lttng-tools 2.0 will not work. > > Is "libust[7848/7853]: " reported from lttng-tools 2.0? Actually, this is > printed from Yeah I think this is normal, this is old stuff that dates from the 0.x days, but lttng-ust still prints it that way.
