perf symbols: Fix builds with NO_LIBELF set
Build currently fails: $ make -C tools/perf O=/tmp/pbuild NO_LIBELF=1 util/symbol.c: In function ‘dso__load’: util/symbol.c:1128:27: error: ‘struct symsrc’ has no member named ‘dynsym’ CC /tmp/pbuild/util/pager.o make: *** [/tmp/pbuild/util/symbol.o] Error 1 make: *** Waiting for unfinished jobs.... Moving the dynsym reference to symbol-elf.c reveals that NO_LIBELF requires NO_LIBUNWIND: $ make -C tools/perf O=/tmp/pbuild NO_LIBELF=1 LINK /tmp/pbuild/perf /tmp/pbuild/libperf.a(unwind.o): In function `elf_section_offset': /opt/sw/ahern/perf.git/tools/perf/util/unwind.c:176: undefined reference to `elf_begin' /opt/sw/ahern/perf.git/tools/perf/util/unwind.c:181: undefined reference to `gelf_getehdr' /tmp/pbuild/libperf.a(unwind.o): In function `elf_section_by_name': /opt/sw/ahern/perf.git/tools/perf/util/unwind.c:157: undefined reference to `elf_nextscn' /opt/sw/ahern/perf.git/tools/perf/util/unwind.c:160: undefined reference to `gelf_getshdr' /opt/sw/ahern/perf.git/tools/perf/util/unwind.c:161: undefined reference to `elf_strptr' /tmp/pbuild/libperf.a(unwind.o): In function `elf_section_offset': /opt/sw/ahern/perf.git/tools/perf/util/unwind.c:190: undefined reference to `elf_end' /tmp/pbuild/libperf.a(unwind.o): In function `read_unwind_spec': /opt/sw/ahern/perf.git/tools/perf/util/unwind.c:190: undefined reference to `elf_end' collect2: ld returned 1 exit status make: *** [/tmp/pbuild/perf] Error 1 make: Leaving directory `/opt/sw/ahern/perf.git/tools/perf' This patch fixes both.
