Error Message: Application Sets Its Own Handler for Signal

Symptoms

When you run a Survey or a Suitability analysis, the following error message appears:
Application sets its own handler for signal
<conflicting_signal>
 that is used for internal needs of the tool. Collection cannot continue
.
This message is for Linux* OS only.

Cause

Intel® Advisor
 cannot profile applications that set up a signal handler for a signal used by the tool.

Possible Solution

This solution is applicable only to the Survey and Suitability analyses.
Do one of the following:
  • When collecting data with
    advisor
     command line interface (CLI), pass the
    --run-pass-thru=--profiling-signal=<not_used_signal>
     option, where
    <not_used_signal>
     is the signal that should not be used by your application. You need to select the signal from
    SIGRTMIN..SIGRTMAX
    . For example, for the matrix multiply (
    mmult
    ) application: 
    advisor --collect=survey --run-pass-thru=--profiling-signal=35 -- ./mmult
  • Before collecting data from the
    Intel Advisor
     GUI or CLI, set the environment variable
    ADVIXE_RUNTOOL_OPTIONS=-- profiling-signal=
    <not_used_signal>
    .
