So, building with:
make -C tools/perf LDFLAGS=-static O=/tmp/build/perf install-bin
I get:
[acme@jouet linux]$ grep libelf /tmp/build/perf/FEATURE-DUMP feature-libelf=0 feature-libelf-getphdrnum=0 feature-libelf-gelf_getnote=0 feature-libelf-getshdrstrndx=0 feature-libelf-mmap=0 [acme@jouet linux]$
And jitdump is only linked if:
[acme@jouet linux]$ grep jitdump tools/perf/*/Build tools/perf/util/Build:libperf-$(CONFIG_LIBELF) += jitdump.o [acme@jouet linux]$
But:
#ifdef HAVE_JITDUMP static int perf_event__jit_repipe_mmap(struct perf_tool *tool, . . . ret = jit_process(inject->session, &inject->output, machine, event->mmap.filename, sample->pid, &n); . . . #endif
So we need:
[acme@jouet linux]$ git diff diff --git a/tools/perf/Makefile.config b/tools/perf/Makefile.config index 8cfc310d4358..cffdd9cf3ebf 100644 --- a/tools/perf/Makefile.config +++ b/tools/perf/Makefile.config @@ -366,8 +366,10 @@ ifndef NO_SDT endif ifdef PERF_HAVE_JITDUMP + ifndef NO_LIBELF $(call detected,CONFIG_JITDUMP) CFLAGS += -DHAVE_JITDUMP + endif endif ifeq ($(ARCH),powerpc) [acme@jouet linux]$ To get that fixed.
Please let me know if this suits your needs.
I'll now try building with elfutils static libraries to see if in that case it all gets linked.
