Linker Error when building from Src fedora 6.1.13-200.fc37.x86_64

Hello,

I have an application written in Cpp and wants to interface it with eBPF. I wanted to successfully run some cpp examples. But I have some trouble with building and it is giving me some linker errors. I followed the instructions and installed all deps specified in [here](https://github.com/iovisor/bcc/blob/master/INSTALL.md#source). When I run `make` I got this problem

```
$make

```
Would anyone have any guidance and solutions on how to resolve the linker errors? Thanks so much in advance
