Subject: [Linux-v5.17-rc6] Building tools/perf with perl v5.34

Hi,

I am here on Debian/unstable AMD64 which switched over to perl v5.34
in February 2022.

Unfortunately, my perf does not build with this (lib)perl version:

$ ~/bin/perf -vv
perf version 5.17-rc6
                dwarf: [ on  ]  # HAVE_DWARF_SUPPORT
   dwarf_getlocations: [ on  ]  # HAVE_DWARF_GETLOCATIONS_SUPPORT
                glibc: [ on  ]  # HAVE_GLIBC_SUPPORT
        syscall_table: [ on  ]  # HAVE_SYSCALL_TABLE_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: [ OFF ]  # 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
                  aio: [ on  ]  # HAVE_AIO_SUPPORT
                 zstd: [ on  ]  # HAVE_ZSTD_SUPPORT
              libpfm4: [ OFF ]  # HAVE_LIBPFM

$ grep libperl ../make-log_perf-python3.10-install_bin.txt
9:Makefile.config:788: Missing perl devel files. Disabling perl
scripting support, please install perl-ExtUtils-Embed/libperl-dev
22:...                       libperl: [ OFF ]

Checking for these requirements:

# dpkg -l | grep perl | grep 5.34 | awk '/^ii/ {print $1 " " $2 " "
$3}' | column -t
ii  libperl-dev:amd64  5.34.0-3
ii  libperl5.34:amd64  5.34.0-3
ii  perl               5.34.0-3
ii  perl-base          5.34.0-3
ii  perl-modules-5.34  5.34.0-3

# dpkg -L perl-modules-5.34 | grep -i ExtUtils | grep -i Embed
/usr/share/perl/5.34.0/ExtUtils/Embed.pm

Can you please comment on this?

Thanks.
