[lttng-dev] Mariadb+LTTng 2.x

[Yang Wang]

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? 

Yang

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.

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.
