Subject: [lttng-dev] ust libc and fork wrapper question
Date: Wed, 28 Aug 2013 14:05:03 -0400 [thread overview]
Message-ID: <521E3BCF.5060500@ericsson.com> (raw)
Hello tracing sages,
I was trying out the libc wrapper in ust. It works very well but does
not follow forks. (to be expected)
So I copied "liblttng-ust-fork.so" into my .libs directory along with
"liblttng-libc-wrapper.so".
I then run
$lttng create thing
$lttng enable-channel chan --buffer-uid
$lttng enable-event -a -k
$lttng start
$LD_PRELOAD="liblttng-ust-fork.so liblttng-libc-wrapper.so" firefox
$lttng stop
$lttng destroy
Aaaaaaaaaaand my trace has no events!
I am certain I am doing something wrong, any suggestions?
Matthew
