[dtrace-discuss] Translator from kthread_t * to psinfo_t * undefined
Hi,
<p>
I am trying to use AppCrash (described here: <a
href="http://developers.sun.com/solaris/articles/app_crash/app_crash.html">Enabling
User-Controlled Collection of Application Crash Data With DTrace</a>) but
the following error pops up:
</p>
<p><tt>
# ./app_crash_global.d<br>
dtrace: failed to compile script ./app_crash_global.d: line 6: translator for
args[1] from kthread_t * to psinfo_t * is not defined

Secondly: # dtrace -lv -n proc:::signal-send ID PROVIDER MODULE FUNCTION NAME 263 proc genunix sigtoproc signal-send ... Argument Types args[0]: lwpsinfo_t * args[1]: psinfo_t * args[2]: int args[1] is a psinfo_t, not a lwpsinfo_t, so it doesn''t have a pr_lwpid field. So your predicate should look like: 5 /(args[2] == SIGBUS || args[2] == SIGSEGV || args[2] == SIGABRT) && 6 pid == args[1]->pr_pid/ But your error message is odd, so I''m not sure the above will work for you. Does it?
