We keep having bug reports that when users build perf on their own, but they don't install some needed libraries such as libelf, libbfd/libibery.
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' 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 perf version 4.13.rc5.g9b7a81b 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 (3): perf config: Add -DNO_GLIBC to CFLAGS perf version: Print the status of compiled-in libraries perf: Support perf -vv
