Re: app. profiler often fails to find source code
Hi Elena,
I'm clicking on totally valid function names - things that have a
'location' with the right source filename (there's only one) and line
number.
I put the SortTest.c code into a QNX C/C++ project - it runs fine and
profiles fine (Function level instrumentation).
I click on .e.g the radix function and the first time it opened the file
correctly. Click again and I get an 'unknown' window for it, or indeed
any other function..
The process has terminated, but the navigation should still work
I've attached a screenshot (I hope it works). Not sure it helps.
I have 6.3.2 installed too, but set the configuration to 6.4.0 before I
started the IDE (and I'm not running 6.3.2 on this Windows machine right
now).
