Description: I think all the symbols in the final binary are
being stripped. This breaks the BEGIN and END probes.

Could not resolve symbol: /proc/self/exe:BEGIN_trigger # bpftrace -e 'END { print(PERF_UPROBE_REF_CTR_OFFSET_SHIFT) }' Attaching 1 probe... ^CCould not resolve symbol: /proc/self/exe:END_trigger $ nm `which bpftrace` nm: /bin/bpftrace: no symbols I'm assuming `strip` is being called somewhere in the build process. One way to keep the symbols is to do something like: https://github.com/iovisor/bpftrace/blob/320338dfd44fea0c5b603a48c70d61b756aa79b1/.github/workflows/embedded.yml#L219 |
