Description PhoenixStarEclipse 2017-12-05 05:31:10 UTC 
I'm using binutils-2.29.1-r1 on Gentoo Linux.
When I'm trying to analyse C and C++ programs, gmon.out is generated successfully, but gprof fails to profile it. gprof only prints an empty profile containing only introduction to indexes like 'time', 'cumulative seconds', 'self seconds' ...... etc.
I've tried to use gprof on different programs, some are C and some are C++, but gprof worked on none of them.

Here's the output of uname -a:

Linux PSE-Gentoo 4.12.12-gentoo #1 SMP Sun Dec 3 14:27:46 CST 2017 x86_64 Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz GenuineIntel GNU/Linux

The two Attachments are the same. It's caused by internet problems.

Seems this is duplicate of Bug 22284 and Bug 21189, so should be closed as "fixed".
