Hi Vincent,
I am not able to reproduce on my system. I don't have libclang1-15 at all and it works. bpftrace is not linked to libclang 15 but to libclang 14. Are you sure bpftrace is the one from the Debian package, not side-compiled version?
ah yes, you're right. Due to some problems in the past I compiled it myself but forgot about that. Sorry about the noise, and thanks for the quick answer!!
