Scaffolding for BPF application development with libbpf and BPF CO-RE
Bit of guide to how prepare Android devices or Emulators to run an eBPF programs compiled for them would be useful due to scarcity of resources on the subject.
While trying to build rust tracecon with LLVM 16, the build was failing. https://github.com/libbpf/libbpf-bootstrap/pull/112 was created to reproduce the issue with CI (like https://github.com/chantra/libbpf-bootstrap/actions/runs/3052027285/jobs/4920947176#step:5:187) The issue turns out to be...

I'm trying to cross-compile some of the programs built on top of libbpf-bootstrap, but I'm lacking expertise with C/C++ ecosystem. I see that support for cross-compilation was added in https://github.com/libbpf/libbpf-bootstrap/commit/7b60b4fd6c6da6af046dc6f618c771f763b6a472...
