Error when compiling the ebpf-profiler

[mingleiw]

I am using UBuntu 18.04 and I was able to use bcc/profile.py. When I was trying to make the ebpf-profiler, I ran into the following error:

clang++ --std=c++17 -o perf_profiler perf_profiler.cc -lbcc
/tmp/perf_profiler-0943c5.o: In function `ebpf::BPF::BPF(unsigned int, ebpf::TableStorage*)':
perf_profiler.cc:(.text._ZN4ebpf3BPFC2EjPNS_12TableStorageE[_ZN4ebpf3BPFC2EjPNS_12TableStorageE]+0x56): undefined reference to `ebpf::BPFModule::BPFModule(unsigned int, ebpf::TableStorage*)'
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Makefile:21: recipe for target 'perf_profiler' failed
make: *** [perf_profiler] Error 1

Is this supported by ubuntu?

I stumbled this, and did a quick check.

This should be BCC's version on your host is too new (or too old). I used 0.16.17-3.3 bcc version, and make is OK. Could you check your bcc version, with:

dpkg -l bcc

If you are using ubuntu. Other OS distros have their own package command for checking version. But you might need to find that yourself.
