Hi,
I just installed uProf 5.0 on a system running RHEL 8.7, and it fails to detect the BCC library and tools:
$ sudo /opt/AMDuProf_5.0-1479/bin/AMDuProfCLI info --bpf
/opt/AMDuProf_5.0-1479/bin/AMDuProfCLI
[OS-Trace Info]
BPF Supported : Yes
BCC Installed : No
OS Tracing Supported : No
Please install the BCC library to support the OS Tracing
If BCC is already installed, please run "AMDuProfVerifyBpfInstallation.sh" with root previlege.
I have installed the BCC tools with:
$ sudo dnf install -y bcc-tools bcc-devel

As far as I can tell BCC is working:

However BCC is never detected by uProf:
