1# libbpf-rs tests
2
3libbpf-rs tests are designed to be independent of libbpf-cargo and underlying
4compiler versions. To that end, we check in pre-compiled bpf object files in
5`libbpf-rs/tests/bin`. To help with writing new tests, the original source
6code for the pre-compiled objects are placed in `libbpf-rs/tests/bin/src`.
7
8To regenerate the test bpf object files
9run bpf_object_regen.sh script via the command:
10$ ./bpf_object_regen.sh
11
12The script bpf_object_regen.sh depends on the following packages installed:
13
14bash
15bpftool (optional)
16clang
17libbpf
