Hi All,
I am tying to use Valgrind to generate code profiling, generated
callgrind.out.2199511 file is of zero size. After enabling the debug
log below message is displayed:
...
==== SB 2759 (evchecks 30598) [tid 1] 0x415b170 execve
/usr/lib/x86_64-linux-gnu/libc-2.31.so+0xe3170

--1314389:1: gdbsrv 1314389 (creator 1314389) maybe unlinking
...
Any idea why it does not generate profiling data? I am new to
Valgrind, so not sure may have missed obvious things. Any
pointers/suggestion are welcome.
Thanking you.
regards,
Mahin
Hi
My guess is that your process is doing a fork/exec (or maybe just an exec).
Try with --trace-children=yes
I'd also recommend that you start with --tool=none before moving on to
callgrind.
A+
