I build perf with NO_DWARF=1 and my spec file does not require libunwind-devel.
With this combination I see perf linking errors such as the following. LINK perf libperf.a(unwind-libdw.o): In function `libdw__arch_set_initial_registers': tools/perf/arch/x86/util/unwind-libdw.c:50: undefined reference to `dwfl_thread_state_registers' This linking error was introduced with commit 0a4f2b6a3ba5066947a8cbd7cfa26fb8a9280625 "perf tools: Setup default dwarf post unwinder" in Linux 3.15-rc1. The above error can also be reproduced with this command line. make -C tools/perf NO_DWARF=1 NO_LIBUNWIND=1 Cheers, Vinson -- To unsubscribe from this list: send the line "unsubscribe linux-perf-users" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
