I'm trying to profile some C ++ code on my Mac (OS X Lion) and I do not know Have found something useful I am looking for a profiler who will tell me how the function is picking up my CPU time (similar to a matlab profiler).

Whatever I have tried here

  • gprof it is on my linux machine, but it only gives me empty output on my mac (apparently a known problem )
  • Equipment I can not understand how to profile anything in my compiled binary for my life. And I can not find any useful tutorials.
  • (Shark detected by other searches, which is no longer available and Valgrind is for memory).

    Really appreciate the help!

    is the tool tool used. A complete description of the tool is outside the scope of this answer, but it is a quick introductory guide:

    1. Open Instruments. 1
    2. "Time Profiler" template.
    3. Choose your app in the "Target" dropdown menu 2
    4. Press the red circle ("Record")
    5. If applicable, do some things in your application that requires a profile.
    6. Hit the record button again to stop the recording.
    7. Use the tool in the tool to analyze your results.

      Of the available devices, these are often the most useful:

      • Expand the call tree
      • Focusing arrows Click on the Function Name to click on
      • Double-click on the function to view the related source
      • On the "Inward Call Tree" checkbox to the left

        1 To use an easy spot, use the device spotlight: just hit the upper right corner of the C taskbar Type lick and watch "tools" on the glass.

        2 Click "Select Target ..." and go on the path to your executable.

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
