Hi,
Currently, I'm using Advanced Hotspots to analyze the executable file resulting from compiling C source code.
However, from the analysis, it showed that most the time was spent in [vmlinux]. And, there is no call stack information displayed when I double click the function [vmlinux] in the Summary window. I'd made link named "vmlinux" to vmlinux-3.13.0-48-generic, which is the debug-info needed.
FYI, my OS is Ubuntu 14.04.2 LTS Trusty Tahr.
Apart from that, I encounter 2 warnings when I run the analysis:
1) Cannot locate debugging symbols for file '/lib/x86_64-linux-gnu/libgcc_s.so.1'.
2) Cannot locate debugging symbols for file '/opt/intel/vtune_amplifier_xe_2015.1.0.367959/lib64/runtime/libittnotify_collector.so'
although I had included the following two paths into "Symbol Search" under "Project Properties":
/opt/intel/vtune_amplifier_xe_2015.1.0.367959/lib64/runtime
/lib/x86_64-linux-gnu
I would like to know why most of the time is spent on executing [vmlinux], view call stack information and also fix the problem of unable to locate debugging symbol.
Thank you.
