The perf can build, but it is missing important functionality. And users may complain that perf has issue or bug. This patch-set support 'perf -vv' and 'perf -version --build-options' which will print the compiled-in status of libraries. Once users think perf missing some functionality, it should be very easy for them to check the libraries status. For example: $ ./perf -vv or ./perf -version --build-options perf version 4.13.rc5.gcb1183 dwarf: [ on ] dwarf_getlocations: [ on ] glibc: [ on ] gtk2: [ on ] libaudit: [ OFF ] libbfd: [ on ] libelf: [ on ] libnuma: [ on ] numa_num_possible_cpus: [ on ] libperl: [ on ] libpython: [ on ] libslang: [ on ] libcrypto: [ on ] libunwind: [ on ] libdw-dwarf-unwind: [ on ] zlib: [ on ] lzma: [ on ] get_cpuid: [ on ] bpf: [ on ] [ on ]: library is compiled-in [ OFF ]: library is disabled in make configuration OR library is not installed in build environment Jin Yao (3): perf config: Add some new -DHAVE_XXX to CFLAGS perf version: Print the compiled-in status of libraries perf: Support perf -vv Jiri Olsa (1): tools include: Add config.h header file tools/include/tools/config.h | 34 ++++++++++++++++++++++ tools/perf/Makefile.config | 16 +++++++++++ tools/perf/builtin-version.c | 68 ++++++++++++++++++++++++++++++++++++++++++++ tools/perf/perf.c | 22 +++++++++++--- tools/perf/perf.h | 1 + 5 files changed, 137 insertions(+), 4 deletions(-) create mode 100644 tools/include/tools/config.h -- 2.7.4
