Profiling application with valgrind and Qt Creator



  • Hello everyone!
    I'm trying to profile my appliaction with Valgrind,
    Launching profiling function analizer, the analizer start correctly with this output

    ==1814== Callgrind, a call-graph generating cache profiler
    ==1814== Copyright (C) 2002-2015, and GNU GPL'd, by Josef Weidendorfer et al.
    ==1814== Using Valgrind-3.12.0.SVN and LibVEX; rerun with -h for copyright info
    ==1814== Command: /Users/mariomeloni/Develop/build/bin/btb
    ==1814== 
    --1814-- warning: L3 cache found, using its data for the LL simulation.
    ==1814== For interactive control, run 'callgrind_control -h'.
    --1814-- UNKNOWN mach_msg unhandled MACH_SEND_TRAILER option
    --1814-- UNKNOWN mach_msg unhandled MACH_SEND_TRAILER option (repeated 2 times)
    --1814-- UNKNOWN mach_msg unhandled MACH_SEND_TRAILER option (repeated 4 times)
    --1814-- UNKNOWN mach_msg unhandled MACH_SEND_TRAILER option (repeated 8 times)
    --1814-- UNKNOWN mach_msg unhandled MACH_SEND_TRAILER option (repeated 16 times)
    

    But, the analysis get stuck for hours and nothing happen.
    I'm talking about an application with 200 c++ classes.

    Is this normal ?
    Any idea about it ?

    Thanks in advanced and sorry for my bad english ;)
    GG.
