I ended up with the one below, _after_ Ian's patch as I had some trouble grafting it before and had already tested it this way multiple times, I'm pushing this to tmp/perf.core. - Arnaldo commit a0ec3ef4590e7e82339b6f318e671a6b69fd94e8 Author: Arnaldo Carvalho de Melo Date: Thu Dec 8 19:28:58 2022 -0300 perf tools: Add test to check if libtracevent has TEP_FIELD_IS_RELATIVE Some distros have older versions of libtraceevent where TEP_FIELD_IS_RELATIVE and its associated semantics are not present, so we need to test for its presence and cope when it isn't present when building with LIBTRACEEVENT_DYNAMIC=1.
