Ok, but are you testing it patch after patch or just after all the patches in this series are applied? Here, with up to: I am getting 'make clean' related errors after some tests on a RHEL7.1 test machine: - make_no_libunwind: cd . && make -f Makefile DESTDIR=/tmp/tmp.CKrCzt1X85 NO_LIBUNWIND=1 find: ‘/home/acme/git/linux/tools/perf/tests/dso-data.o’: No such file or directory find: ‘/home/acme/git/linux/tools/perf/tests/.dso-data.o.cmd’: No such file or directory find: ‘/home/acme/git/linux/tools/perf/tests/pmu.o’: No such file or directory find: ‘/home/acme/git/linux/tools/perf/tests/sw-clock.o’: No such file or directory find: ‘/home/acme/git/linux/tools/perf/tests/.sample-parsing.o.cmd’: No such file or directory find: ‘/home/acme/git/linux/tools/perf/tests/attr.o’: No such file or directory - make_help: cd . && make -f Makefile DESTDIR=/tmp/tmp.9Gcw1OfooR help - make_no_slang: cd . && make -f Makefile DESTDIR=/tmp/tmp.Ce5PSg2snH NO_SLANG=1 And 'build-test' fails when it tries to run the 'make_static' target and that is not the first one to be run: - make_no_libelf: cd . && make -f Makefile DESTDIR=/tmp/tmp.tEwrxaQPOB NO_LIBELF=1 - make_no_libdw_dwarf_unwind: cd . && make -f Makefile DESTDIR=/tmp/tmp.4r7zlxeeAA NO_LIBDW_DWARF_UNWIND=1 - make_no_libnuma: cd . && make -f Makefile DESTDIR=/tmp/tmp.XuaZ3SACwX NO_LIBNUMA=1 - make_perf_o: cd . && make -f Makefile DESTDIR=/tmp/tmp.LXh3STdaiO perf.o - make_static: cd . && make -f Makefile DESTDIR=/tmp/tmp.xii2W5SLf2 LDFLAGS=-static cd . && make -f Makefile DESTDIR=/tmp/tmp.xii2W5SLf2 LDFLAGS=-static BUILD: Doing 'make -j4' parallel build Auto-detecting system features: ... dwarf: [ on ] ... glibc: [ on ] ... gtk2: [ on ] ... libaudit: [ on ] ... libbfd: [ on ] ... libelf: [ on ] ... libnuma: [ on ] ... numa_num_possible_cpus: [ on ] ... libperl: [ on ] ... libpython: [ on ] ... libslang: [ on ] ... libunwind: [ on ] ... libdw-dwarf-unwind: [ on ] ... zlib: [ on ] ... lzma: [ on ] ... get_cpuid: [ on ] ... bpf: [ on ] GEN common-cmds.h PERF_VERSION = 4.4.gbe874d2 CC plugin_hrtimer.o <SNIP> CC util/zlib.o CC util/lzma.o FLEX util/parse-events-flex.c FLEX util/pmu-flex.c CC util/pmu-bison.o CC util/parse-events.o CC util/parse-events-flex.o CC util/pmu.o CC util/pmu-flex.o LD util/libperf-in.o LD libperf-in.o AR libperf.a /usr/bin/ld: /usr/lib/gcc/x86_64-redhat-linux/4.8.5/crtbeginT.o: relocation R_X86_64_32 against `__TMC_END__' can not be used when making a shared object; recompile with -fPIC /usr/lib/gcc/x86_64-redhat-linux/4.8.5/crtbeginT.o: could not read symbols: Bad value collect2: error: ld returned 1 exit status error: command 'gcc' failed with exit status 1 cp: cannot stat ‘python_ext_build/lib/perf.so’: No such file or directory make[4]: *** [python/perf.so] Error 1 make[3]: *** [all] Error 2 test: test -x ./perf make[2]: *** [make_static] Error 1 make[1]: *** [all] Error 2 make: *** [build-test] Error 2 make: Leaving directory `/home/acme/git/linux/tools/perf' ------------------- If I try it manually, in the source tree: [acme@...icio linux]$ cd tools/perf [acme@...icio perf]$ make LDFLAGS=-static BUILD: Doing 'make -j4' parallel build GEN libtraceevent-dynamic-list LINK libperf-gtk.so /usr/bin/ld: /usr/lib/gcc/x86_64-redhat-linux/4.8.5/crtbeginT.o: relocation R_X86_64_32 against `__TMC_END__' can not be used when making a shared object; recompile with -fPIC /usr/lib/gcc/x86_64-redhat-linux/4.8.5/crtbeginT.o: could not read symbols: Bad value collect2: error: ld returned 1 exit status make[1]: *** [libperf-gtk.so] Error 1 make: *** [all] Error 2 [acme@...icio perf]$ And if I do a make clean and try again, it works: [acme@...icio perf]$ make clean CLEAN libtraceevent CLEAN libapi CLEAN libbpf CLEAN libsubcmd CLEAN libsubcmd CLEAN config CLEAN core-objs CLEAN core-progs CLEAN core-gen SUBDIR Documentation CLEAN Documentation CLEAN python [acme@...icio perf]$ make LDFLAGS=-static BUILD: Doing 'make -j4' parallel build Auto-detecting system features: ... dwarf: [ OFF ] ... glibc: [ on ] ... gtk2: [ OFF ] ... libaudit: [ OFF ] ... libbfd: [ OFF ] ... libelf: [ on ] ... libnuma: [ OFF ] ... numa_num_possible_cpus: [ OFF ] ... libperl: [ OFF ] ... libpython: [ OFF ] ... libslang: [ OFF ] ... libunwind: [ OFF ] ... libdw-dwarf-unwind: [ OFF ] ... zlib: [ OFF ] ... lzma: [ OFF ] ... get_cpuid: [ on ] ... bpf: [ on ] config/Makefile:268: No libdw DWARF unwind found, Please install elfutils-devel/libdw-dev >= 0.158 and/or set LIBDW_DIR config/Makefile:272: No libdw.h found or old libdw.h found or elfutils is older than 0.138, disables dwarf support.
