Cannot locate debugging symbol

Hi,

I'm new in using profiling tools. I have few questions:

1) Does Intel VTune Amplifier XE 2015 currently have the specific feature of analyzing the performance of a source code on implementing OpenMP API?

2) When I tried to run Advanced Hotspots Analysis, it was completed with the warning:

cannot locate debugging symbols for file '/lib/x86_64-linux/libc-2.19.so'.

cannot locate debugging symbols for file '/lib/x86_64-linux/ld-2.19.so'.

3) What is the effect of missing debugging symbols?

4) When I was about to use VTune to perform analysis on OpenMP region, it displayed nothing. It is because of my OS version? Below is the info of my OS:

My OS: Linux Mint 17 Cinnamon 64-bit

Cinnamon Version: 2.2.13

Linux Kernel: 3.13.0-24-generic
