Perf Proce不适用于我想要的特定事件

我已经编译了获取一些统计信息。我尝试过的是为感兴趣的特定功能设置探针，即kerrbl :: chrostoffel lib/kerbc.c。但是，如果我尝试运行

perf Proce -x/usr/local/bin/gyoto -f

无法显示我想要的此特定功能。尝试使用

perf Proce -x/usr/locar/bin/gyoto [args]'kerrbl :: chrostoffel'

引发错误：

The /home/user/Gyoto/bin/gyoto file has no debug information.
Rebuild with -g, or install an appropriate debuginfo package.
Error: Failed to add events.

但是据我所知，我确实启用调试信息在汇编期间。

在此特定情况下，我应该如何正确放置探测器？

I have compiled this open source software and would like to use perf to get some statistics. What I have tried is setting probes for the specific function of interest, namely KerrBL::chrostoffel inside lib/KerBC.C. But if I try running

perf probe -x /usr/local/bin/gyoto -F

Fails to show this specific function that I want. Trying to place a probe with

perf probe -x /usr/local/bin/gyoto [args] 'KerrBL::chrostoffel'

throws the error:

The /home/user/Gyoto/bin/gyoto file has no debug information.
Rebuild with -g, or install an appropriate debuginfo package.
Error: Failed to add events.

But as far as I know, I did enable debug info during compilation.

How should I properly place a probe in this specific case?
