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 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.g6727c5 dwarf: [ on ] # HAVE_DWARF_SUPPORT dwarf_getlocations: [ on ] # HAVE_DWARF_GETLOCATIONS_SUPPORT glibc: [ on ] # HAVE_GLIBC_SUPPORT gtk2: [ on ] # HAVE_GTK2_SUPPORT libaudit: [ OFF ] # HAVE_LIBAUDIT_SUPPORT libbfd: [ on ] # HAVE_LIBBFD_SUPPORT libelf: [ on ] # HAVE_LIBELF_SUPPORT libnuma: [ on ] # HAVE_LIBNUMA_SUPPORT numa_num_possible_cpus: [ on ] # HAVE_LIBNUMA_SUPPORT libperl: [ on ] # HAVE_LIBPERL_SUPPORT libpython: [ on ] # HAVE_LIBPYTHON_SUPPORT libslang: [ on ] # HAVE_SLANG_SUPPORT libcrypto: [ on ] # HAVE_LIBCRYPTO_SUPPORT libunwind: [ on ] # HAVE_LIBUNWIND_SUPPORT libdw-dwarf-unwind: [ on ] # HAVE_DWARF_SUPPORT zlib: [ on ] # HAVE_ZLIB_SUPPORT lzma: [ on ] # HAVE_LZMA_SUPPORT get_cpuid: [ on ] # HAVE_AUXTRACE_SUPPORT bpf: [ on ] # HAVE_LIBBPF_SUPPORT
v4: --- 1. Also print the macro name. That would make it easier to grep around in the source looking for where code related a particular features is located.
2. Update since HAVE_DWARF_GETLOCATIONS is renamed to HAVE_DWARF_GETLOCATIONS_SUPPORT
Patch impacted: --------------- perf config: Rename to HAVE_DWARF_GETLOCATIONS_SUPPORT perf version: Print the compiled-in status of libraries others not changed
Jin Yao (5): perf config: Add some new -DHAVE_XXX to CFLAGS perf config: Rename to HAVE_DWARF_GETLOCATIONS_SUPPORT 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
