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.
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?
Looking forward to building with CO-RE and move some of my BCC tooling to libbpf.
