Hi all,

Finally found the BPF blog and it's been nice to get more information on using libbpf directly since I don't have a lot of systems or kernel experience.
Thanks! Glad it was useful.


Scanning through the "BCC to libbpf" post, I noticed Andrii calls for using clang 10. I went to look at llvm releases and only saw clang/llvm 9 (as of September 2019).
Is clang 10 just built from source?
For kernel/libbpf development we do build Clang from sources, but you
can install it from packages as well. See https://apt.llvm.org/, there
are packages for Clang 10 and even Clang 11 and they are updated
frequently.


Looking forward to building with CO-RE and move some of my BCC tooling to libbpf.
Great, please do!
