The perf can build, but it is missing important functionality. And users may complain that perf has issue or bug. This patch-set support to print the status of compiled-in libraries. Once users think perf missing some functionality, it should be very easy for them to check the libraries status. For example: $ ./perf version --build-options or ./perf --version --build-options or ./perf -v --build-options or ./perf -vv perf version 4.13.rc5.g4c1df1 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 ] Jin Yao (4): perf config: Add some new -DHAVE_XXX to CFLAGS perf version: Print the compiled-in status of libraries perf: Support perf -vv perf Documentation: Create perf-version.txt Jiri Olsa (1): tools include: Add config.h header file tools/include/tools/config.h | 34 +++++++++++++ tools/perf/Documentation/perf-version.txt | 24 +++++++++ tools/perf/Makefile.config | 6 +++ tools/perf/builtin-version.c | 81 ++++++++++++++++++++++++++++++- tools/perf/perf.c | 6 +++ tools/perf/perf.h | 1 + 6 files changed, 151 insertions(+), 1 deletion(-) create mode 100644 tools/include/tools/config.h create mode 100644 tools/perf/Documentation/perf-version.txt -- 2.7.4
