XCode 4.1 - Instruments Time Profiler

1
votes

I'm trying to use Time Profiler, I've used it before.

I'm hiding system libraries, but all of my symbol names are HEX.

I'm running in debug, I have debugSymbols turned on....

I've restarted everything a few times and cleaned everything in between..

... anybody got any other ideas?

it's a bit of a pain because there are a number of variables that can cause this. some of the more common ones are:

sometimes you need to tell instruments where to find your files and/or symbols (Preferences->Search Paths).

have you enabled Link Time Optimization (LTO)? it should be off.

sometimes it helps if you do a clean/build.

sometimes it helps if you restart instruments.

in earlier versions of Xcode, it helped to use a central build directory.

verify that you are generating the proper level of debug symbols for all targets.

I no longer get this problem with the latest version.

Apple were no help in answering this for me - even though I used one of my Tech Support Requests. Must have had them stumped too.
