With the Fedora mapping in place, this patch extends it to the RHEL
family (RHEL, CentOS Stream, Rocky Linux, AlmaLinux, Oracle Linux),
which shares most Fedora package names and runs dnf (RHEL 8 and
later). The names that differ are handled by probing the enabled
repos:
- zlib.h comes from zlib-ng-compat-devel on the RHEL 10 family,
zlib-devel on RHEL 9 and earlier;
- there is no java-latest-openjdk-devel: the JDK devel package is
versioned per release, java-21-openjdk-devel on the RHEL 10
family, java-17-openjdk-devel on RHEL 9, java-11-openjdk-devel
on RHEL 8;
- libbpf-devel and capstone-devel live in the CRB repo on RHEL and
CentOS Stream 10, in EPEL on RHEL 9 and earlier;
- libbabeltrace2-devel is not packaged on the RHEL 10 family.
Packages not available on the enabled repos are skipped instead of
aborting the dnf transaction, and are listed at the end of the run, with
the repo that provides them pointed out in the header comment and help
text: a distro with CRB/EPEL enabled gets the full set, one without them
still installs what it can.
This also holds for the base set: e.g. 'rust' exists only as the
rust-toolset AppStream module on RHEL 8 and 9, where it is not
installable as a plain package, so it is skipped and noted there instead
of failing the whole dnf transaction.
The base set lists pkgconf-pkg-config instead of pkgconfig: both
families have been on pkgconf since Fedora 26 / RHEL 8, where
'pkgconfig' lives only as a virtual Provides of that subpackage, and
a minimal RHEL-family container may not have it preinstalled.
Validated on a fresh CentOS Stream 10 distrobox container, with the
CRB repo enabled, so the host system is not modified:
distrobox create --image quay.io/centos/centos:stream10
distrobox enter centos-stream10
dnf config-manager --set-enabled crb
make -C tools/perf install-build-deps
which installed the 28 available mapped packages; libbabeltrace2-devel, the
only mapped package with no RHEL 10 package, is reported at the end
of the run.
A subsequent 'make -C tools/perf feature-dump' enabled every feature
with an external dependency the RHEL 10 family provides, including
libbpf and libcapstone from the CRB repo, with only
babeltrace2-ctf-writer left out along with the deliberately unmapped
opt-in features.
Re-running the target is a no-op (dnf reports "Nothing to do"); with the
CRB repo disabled, the skipped packages are instead listed in the
end-of-run note, whose header comment and help text point out which repo
provides them.
Members of the family without dnf (RHEL 7 and earlier, e.g. Oracle
Linux 7, a yum-only distro) are rejected with an explicit error while
the dnf-based members get the full mapping.

With the Fedora and Ubuntu mappings in place, this patch adds Debian
support: Debian installs the same devel packages, under the same
names, as the Ubuntu mapping, so it reuses debian_pkg_for() and
debian_base_pkgs as-is, with only auto-detection in detect_distro()
(and the shared apt-get install path) added, keeping the script's
per-distro dispatch ready for distros with their own package names.
Validated on a fresh Debian 13 (trixie) container so the host system
is not modified:
distrobox create --image debian:trixie
distrobox enter debian-trixie
make -C tools/perf install-build-deps
which installed the 29 mapped packages; re-running the target is a
no-op (apt-get reports "0 newly installed"). A subsequent clean build
enabled the same feature set as Ubuntu: 'perf version --build-options'
shows every feature with an external dependency Debian has a package
for [on], including the BPF skeletons compiled with clang/llvm
(libLLVM), the python binding and the C++-based features, with only
the deliberately unmapped libbfd family, libperl, libunwind and the
CoreSight (libopencsd) packages [OFF].
RHEL, whose package mapping is largely similar to Fedora's, is the
remaining planned distro, to be enabled once that mapping is
validated on it.

With the framework and Fedora mapping in place, this patch adds the
Ubuntu (apt) mapping: same feature-to-package correspondence as the
Fedora one, adapted to Debian packaging conventions (libfoo-dev), on
a per-distro dispatch so future distros can pick their own mapping or
reuse one of these (Debian shares the Ubuntu mapping).
Notable differences from Fedora:
- base set: g++ (ships libstdc++-*-dev, covering cxa-demangle),
pkg-config (installed implicitly by Fedora's default toolchain
metapackage, but not by Ubuntu's), linux-libc-dev and libc6-dev
instead of kernel-headers and glibc-devel, and rustc for rust;
- cxa-demangle maps to nothing, covered by g++'s libstdc++;
- the clang-bpf-co-re test needs the clang compiler binary (Fedora's
clang-devel provides it transitively), and llvm-dev, which also
brings llvm-config (deps on the llvm package), used by the
llvm/llvm-perf tests;
- libslang maps to libslang2-dev and jvmti to default-jdk;
- the install command runs 'apt-get update' first since a fresh
container has no package indexes, unlike dnf.
Validated on a fresh Ubuntu 26.04 distrobox container so the host
system is not modified:
distrobox create --image ubuntu:26.04
distrobox enter ubuntu-26-04
make -C tools/perf install-build-deps
which installed the 29 mapped packages; a subsequent clean O= build
enabled every feature with an external dependency Ubuntu has a
package for: perf's build-options then showed all of them [on],
including the BPF skeletons requiring clang/llvm, the python binding
and the C++-based features, with only the deliberately unmapped
(deprecated) libbfd family, libperl and libunwind [OFF], and the
build linked libpfm, libbabeltrace2-ctf-writer, libcapstone,
libtraceevent, libslang, libnuma, libdw and libssl. Re-running the
target is a no-op (apt-get reports "0 newly installed").
Debian (trixie) is the next planned distro: it shares this Ubuntu
mapping, so enabling it reuses it as-is, once it gets validated on a
Debian release.

With the framework from the previous commit in place, this patch adds
the per-feature mapping for Fedora/dnf: for each feature test in
tools/build/feature/, the Fedora devel package providing the headers
or library the test compiles against, kept explicit in the script
next to the test that requires it.
Special cases:
- test-libdebuginfod.c includes <elfutils/debuginfod.h>, provided
by elfutils-debuginfod-client-devel, not elfutils-devel;
- the cxa-demangle test links against libstdc++'s builtin demangler,
pulling in libstdc++-devel;
- the BPF-oriented features (bpf, clang-bpf-co-re) get their headers
from the base packages and clang-devel.
Tests with no Fedora equivalent (bionic, compile-32, compile-x32) and
the opt-in/deprecated ones (libbfd disassembler family, GTK2, LIBPERL,
LIBUNWIND, CoreSight, and the tests perf itself doesn't check, like
libcpupower) are deliberately not mapped.
Validated on a fresh Fedora 44 toolbx container, so the host OS is not
modified:
toolbox create fedora:44
toolbox enter fedora:44
make -C tools/perf install-build-deps
which installed the 29 mapped packages; a subsequent clean O= build
enabled every feature with an external dependency Fedora provides
(feature tests went to 1, except bionic/compile-32/compile-x32, which
have no Fedora equivalent, and the libunwind-debug-frame tests, whose
symbols Fedora's libunwind does not export), linking libpfm,
libbabeltrace2-ctf-writer, libcapstone, libtraceevent, libslang and
libnuma, as well as building the BPF skeletons requiring clang/llvm.
Re-running the target is a no-op (dnf reports "Nothing to do").
RHEL and its derivatives share most Fedora package names but are
refused by the script until this mapping is validated on them.

$ grep PRETTY_NAME /etc/os-release

Installing the development packages needed to build perf is
error-prone on a fresh distro install: the packages are scattered
across the feature tests in tools/build/feature/, each checking for a
specific header/library, and the build only tells you what's missing
after failing a check.
This series adds a 'make -C tools/perf install-build-deps' target to
install them in one go, deriving the package list from the feature tests
themselves.
This commit adds the framework, on top of the parse-time compiler
probe guard from the previous commit:
- the install-build-deps target in tools/perf/Makefile.perf, exempted
from the config/feature detection pass, since it must run in a fresh
container, before gcc or pkg-config exist, to install them;
- the install-build-deps.sh script, with --list, --dry-run and
--distro options, distro detection (Fedora and Ubuntu), dnf and
apt-get drivers, root/passwordless-sudo handling, and the base
packages common to any build: compiler, C++ compiler, make, flex,
bison, libc and kernel headers, python3-setuptools (needed by the
python binding) and rust (checked by the rust feature test);
- the parse-time probes for optional tools, like pkg-config, use
'command -v' with stderr discarded, so a fresh container without
them gets no 'which: no pkg-config in (...)' spew from make;
- the script does not rely on 'set -e': its error paths are explicit,
since the make target runs it via $(SHELL), where a shebang option
would be ignored anyway, so direct and make-driven runs behave the
same.
The per-feature mappings, from each feature test to the devel package
providing its headers on a given distro, are added by the follow-up
patches, one per distro, together with the validation of each mapping
in a fresh container: until then the target installs just the base
toolchain.
