Hi, Arnaldo raised defaulting BUiLD_BPF_SKEL in the perf tool build: https://lore.kernel.org/lkml/Y3Yy5DFEoCEBv%2FQi@xxxxxxxxxx/ The recent build clean up: https://lore.kernel.org/lkml/20221109184914.1357295-1-irogers@xxxxxxxxxx/ https://lore.kernel.org/lkml/20221116224631.207631-1-irogers@xxxxxxxxxx/ Means that perf is cleanly(ish) separated from libraries in tools/lib. traceevent in tools/lib is out of date (~2years - version 1.1.0 whilst the latest is 1.6.3 [1]) . Should we delete traceevent from tools/lib and just make LIBTRACEEVENT_DYNAMIC the only supported perf build option? I guess this may break old distributions that may not have libtraceevent, but even so I'm not sure that should motivate not cleaning this up (if they are building perf they can build libtraceevent). Thanks, Ian [1] https://git.kernel.org/pub/scm/libs/libtrace/libtraceevent.git/tree/Makefile
