![]() The bpf.h file needed gets installed in /usr/lib/include/perf/bpf/bpf.h, and /usr/lib/include/perf/ is added to the include path passed to clang to build the eBPF bytecode, so just remove "bpf/", its directly in the path passed already. This was working by accident, fix it. I.e. now this is back working: # cat /home/acme/git/perf/tools/perf/examples/bpf/hello.c #include <stdio.h> int syscall_enter(openat)(void *args) { puts("Hello, world\n"); return 0; } license(GPL); # perf trace -e /home/acme/git/perf/tools/perf/examples/bpf/hello.c 0.000 pickup/21493 __bpf_stdout__(Hello, world) 56.462 sh/13539 __bpf_stdout__(Hello, world) 56.536 sh/13539 __bpf_stdout__(Hello, world) 56.673 sh/13539 __bpf_stdout__(Hello, world) 56.781 sh/13539 __bpf_stdout__(Hello, world) 56.707 perf/13182 __bpf_stdout__(Hello, world) 56.849 perf/13182 __bpf_stdout__(Hello, world) ^C # Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Link: https://lkml.kernel.org/n/tip-d9myswhgo8gfi3vmehdqpxa7@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
