Error: unknown argument: '-fcf-protection'
I installed bcc on my Ubuntu 18.04 server, and I tried to test if bcc has been successfully installed with bcc tools, I run './tcptop.py' but get ModuleNotFoundError: No module named bcc then I changed to 'python3 ./tcptop.py' and got 2 lines error: error:unknown argument: '-fcf-protection' LLVM ERROR: What's wrong with this?
The same issue was encountered while running official_hello_fields.py or any other progs that run smoothly on other machines. It may be due to the kernel version being too old.
Sys info for my machines that encountered issues:
OS: Ubuntu 18.04.6 LTS x86
Kernel: 4.15.0-213-generic
On this machine most progs run successfully:
OS: Ubuntu 20.04 LTS x86
I hope it might help u.
The failure in ubuntu 18.04 is due to old compiler. The flag "-fcf-protection" likely unsupported by the compiler on 18.04. Ubuntu 18.04 has been depreciated, please use a newer ubuntu version.
