Prerequisites for building NUT on different OSes
================================================
endif::website[]
This chapter aims to list packages with the tools needed on a freshly minimally
deployed worker to build as many targets of NUT recipes as possible, mainly
the diverse driver and documentation types.
NUT codebase generally should not depend on particular operating system or
kernel technology and version, and with the operating systems listed below
one can benefit from use of containers (jails, zones) to build and test
against numerous OS distributions on one physical or virtual machine,
e.g. to cover non-regression with older tool kits while taking advantage
of new releases.
* For Linux systems, we have notes on link:ci-farm-lxc-setup.txt[Setting
up the multi-arch Linux LXC container farm for NUT CI]
Some of the below are alternatives, e.g. compiler toolkits (gcc vs. clang)
or SSL implementations (OpenSSL vs. Mozilla NSS) -- no problem installing
both, at a disk space cost.
[NOTE]
======
Some NUT branches may need additional or different software versions
that are not yet included into `master` branch dependencies, e.g. the DMF
(Dynamic Mapping Files) sub-project needs LUA 5.1 for build and run-time,
and some Python modules for build, e.g. using OS packaging or custom call
to `pip install pycparser`.
In case your system still provides a Python 2.x environment (and for some
reason you want to use it instead of Python 3.x), but does not anymore
provide a `pip` nor `pycparser` packages for it, you may need to use an
external bootstrap first, e.g.:
------
# Fetch get-pip.py for python 2.7
:; curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output get-pip.py
:; python2 get-pip.py
:; python2 -m pip --version
:; python2 -m pip install pycparser
------
======
More packages and/or system setup may be needed to actually run NUT with
all features enabled; chapters below concern just with building it.
General call to Test the ability to configure and build
-------------------------------------------------------
Check out from git, generate files and configure to tailor to your build
environment, and build some tests:
------
:; mkdir -p nut && cd nut && \
git clone https://github.com/networkupstools/nut/ -b master .
:; ./autogen.sh && \
./configure --with-doc=all --with-all --with-cgi && \
make all && make check && make spellcheck
------
You can toggle some `configure` options to check different dependency
variants, e.g. `--with-ssl=nss` vs. `--with-ssl=openssl`
For reproducible runs of various pre-sets of configuration during
development, take a look at `ci_build.sh` script and different `BUILD_TYPE`
(and other) environment variable settings that it supports. A minimal run
with it is just to call the script, e.g.:
------
:; mkdir -p nut && cd nut && \
git clone https://github.com/networkupstools/nut/ -b fightwarn .
:; ./ci_build.sh
------
[NOTE]
======
To build older releases, such as "vanilla" NUT 2.7.4 and older,
you may need to address some nuances:
* Ensure that `python` in `PATH` points to a python-2.x implementation
(`master` branch is fixed to work with python 2 and 3)
* Ensure that `bash` is your user and maybe system shell (or ensure the
generated `configure` script gets interpreted by it)
* Generally you may have better results with GNU Make newer than 3.81
than with other make implementations; however, builds are regularly
tested by CI with Sun dmake and BSD make as well, so recipes should
not expect GNU-only syntax and constructs to work
* Parallel builds should be okay in current development version and
since NUT 2.8.0 (is a bug to log and fix, if not), but they may be
failure-prone in 2.7.4 and earlier releases
======
For intensive rebuilds, `ccache` is recommended. Note that instructions
below detail how to provide its directory with symlinks as `/usr/lib/ccache`
which is not the default case in all OS distributions. Recent versions of
the NUT `ci_build.sh` script allow to override the location by using the
`CI_CCACHE_SYMLINKDIR` environment variable, which is cumbersome and only
recommended for build agents with immutable system areas, etc.
Build prerequisites to make NUT from scratch on various Operating Systems
-------------------------------------------------------------------------
Debian 10/11/12
~~~~~~~~~~~~~~~
Being a popular baseline among Linux distributions, Debian is an
important build target. Related common operating systems include
Ubuntu and customized distros for Raspberry Pi, Proxmox, as well
as many others.
For some (newer) distributions, `apt` or other front-ends may be
preferable to `apt-get`, but otherwise the commands are equivalent.
The package list below should largely apply to those as well,
however note that some well-known package names tend to differ.
A few of those are noted below.
[NOTE]
======
While Debian distros I've seen (8 to 11) provide a "libusb-dev"
for libusb-0.1 headers, the binary library package name is specifically
versioned package by default of the current release (e.g. "libusb-0.1-4"),
while names of both the library and development packages for libusb-1.0
must be determined with:
------
:; apt-cache search 'libusb.*1\.0.*'
------
yielding e.g. "libusb-1.0-0-dev" (string name was seen with different
actual package source versions on both Debian 8 "Jessie" and
Debian 11 "Buster").
======
[NOTE]
.FUN NOTE
======
For development on the road (or a native ARM build) you can use the
link:https://termux.dev/en/[Termux] project on Android. It provides
a sufficiently Debian-like operating environment for all intents and
purposes, but you may have to use their `pkg` wrapper instead of `apt`
tooling directly, and `ldd` may be in a package separate from `binutils`,
but otherwise the Debian/Ubuntu oriented lists of packages below apply.
You would need at least a couple of gigabytes available on the internal
phone storage though, especially if using `ccache` or setting up cross
builds.
The Termux distribution as of this writing seems to lack cppunit packages
but you can build it from https://www.freedesktop.org/wiki/Software/cppunit/
e.g. `--with-prefix=${HOME}/nut-deps/usr` and `make install` there.
A custom `PKG_CONFIG_PATH=${HOME}/nut-deps/usr/lib/pkgconfig` would find
it during NUT build.
======
Debian-like package installations commonly start with an update of
metadata about recently published package revisions:
------
:; apt-get update
:; apt-get install \
ccache time \
git perl curl \
make autoconf automake libltdl-dev libtool binutils \
valgrind \
cppcheck \
pkg-config \
gcc g++ clang
# To debug eventual core dump files, or trace programs with an IDE like
# NetBeans (perhaps remotely), you may want the GNU Debugger program:
:; apt-get install \
gdb
# NOTE: Older Debian-like distributions may lack a "libtool-bin"
:; apt-get install \
libtool-bin
# See comments below, python version and package naming depends on distro
:; apt-get install \
python
# NOTE: For python, you may eventually have to specify a variant like this
# (numbers depending on default or additional packages of your distro):
# :; apt-get install python2 python2.7 python-is-python2
# and/or:
# :; apt-get install python3 python3.9
# You can find a list of what is (pre-)installed with:
# :; dpkg -l | grep -Ei 'perl|python'
#
# For localization maintenance (currently in Python NUT-Monitor app),
# provide an `msgfmt` implementation, e.g.:
# :; apt-get install gettext
#
# To install the Python NUT-Monitor app, you may need some modules:
# :; apt-get install pip
# For Python3:
# :; python3 -m pip install PyQt5 configparser
# For spell-checking, highly recommended if you would propose pull requests:

Alternatives that can depend on your system's other packaging choices:
------
:; apt-get install libneon27-dev
# ... or
:; apt-get install libneon27-gnutls-dev
------
Over time, Debian and Ubuntu had different packages and libraries providing
the actual methods for I2C; if your system lacks the `libi2c` (and so fails
to `./configure --with-all`), try adding the following packages:
------
:; apt-get install build-essential git-core libi2c-dev i2c-tools lm-sensors
------
For cross-builds (note that not everything supports multilib approach,
limiting standard package installations to one or another implementation;
in that case local containers each with one ARCH may be a better choice,
with `qemu-user-static` playing a role to "natively" run the other-ARCH
complete environments):
------
:; apt-get install \
gcc-multilib g++-multilib \
crossbuild-essential \
gcc-10:armhf gcc-10-base:armhf \
qemu-user-static
------
NOTE: For Jenkins agents, also need to `apt-get install openjdk-17-jdk-headless`.
You may have to ensure that `/proc` is mounted in the target chroot
(or do this from the running container).
CentOS 6 and 7
~~~~~~~~~~~~~~
CentOS is another popular baseline among Linux distributions, being a free
derivative of the RedHat Linux, upon which many other distros are based as
well. These systems typically use the RPM package manager, using directly
`rpm` command, or `yum` or `dnf` front-ends depending on their generation.
For CI farm container setup, prepared root filesystem archives from
http://download.proxmox.com/images/system/ worked sufficiently well.
Prepare CentOS repository mirrors
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
For CentOS 7 it seems that not all repositories are equally good; some of
the software below is only served by EPEL (Extra Packages for Enterprise
Linux), as detailed at:
* https://docs.fedoraproject.org/en-US/epel/
* https://www.redhat.com/en/blog/whats-epel-and-how-do-i-use-it
* https://pkgs.org/download/epel-release
You may have to specify a mirror as the `baseurl` in a `/etc/yum.repos.d/...`
file (as the aged distributions become less served by mirrors), such as:
* https://www.mirrorservice.org/sites/dl.fedoraproject.org/pub/epel/7/x86_64/
+
------
# e.g. for CentOS7 currently:
:; yum install https://download-ib01.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-14.noarch.rpm
# And edit /etc/yum.repos.d/epel.repo to uncomment and set the baseurl=...
# lines, and comment away the mirrorlist= lines (if yum hiccups otherwise)
------
For systemd support on CentOS 7 (no equivalent found for CentOS 6),
you can use backports repository below:
------
:; curl https://copr.fedorainfracloud.org/coprs/jsynacek/systemd-backports-for-centos-7
> /etc/yum.repos.d/systemd-backports-for-centos-7.repo
------
For CentOS 6 (the oldest I could try) the situation is similar, with sites like
https://www.getpagespeed.com/server-setup/how-to-fix-yum-after-centos-6-went-eol
detailing how to replace `/etc/yum.repos.d/` contents (you can wholesale rename
the existing directory and populate a new one with `curl` downloads from the
article), and additional key trust for EPEL packages:
------
:; yum install https://dl.fedoraproject.org/pub/archive/epel/6/x86_64/epel-release-6-8.noarch.rpm
------
Set up CentOS packages for NUT
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Instructions below apply to both CentOS 6 and 7 (a few nuances for 6 commented).
For newer distributions, `dnf` may be preferable to `yum`, but otherwise the
commands are equivalent.
General developer system helpers mentioned in link:ci-farm-lxc-setup.txt[]:
------
:; yum update
:; yum install \
sudo vim mc p7zip pigz pbzip2 tar
------
To have SSH access to the build VM/Container, you may have to install and
enable it:
------
:; yum install \
openssh-server openssh-clients
:; chkconfig sshd on
:; service sshd start
# If there are errors loading generated host keys, remove mentioned files
# including the one with .pub extension and retry with:
#:; service sshd restart
------
NOTE: Below we request to install generic `python` per system defaults.
You may request specifically `python2` or `python3` (or both): current
NUT should be compatible with both (2.7+ at least).
NOTE: On CentOS, `libusb` means 0.1.x and `libusbx` means 1.x.x API version
(latter is not available for CentOS 6).
NOTE: On CentOS, it seems that development against libi2c/smbus is not
supported. Neither the suitable devel packages were found, nor i2c-based
drivers in distro packaging of NUT. Resolution and doc PRs are welcome.

NOTE: `busybox` is not packaged for CentOS 7 release; a static binary can
be downloaded if needed. For more details, see
https://unix.stackexchange.com/questions/475584/cannot-install-busybox-on-centos
CentOS packaging for 64-bit systems delivers the directory for dispatching
compiler symlinks as `/usr/lib64/ccache`. You can set it up same way as for
other described environments by adding a symlink `/usr/lib/ccache`:
------
:; ln -s ../lib64/ccache/ "$ALTROOT"/usr/lib/
------
[NOTE]
======
For Jenkins agents, also need to install JDK 17 or newer, which is not
available for CentOS 6 nor 7 directly (in distribution packaging).
Alternative packaging, such as Temurin from the Adoptium project, is possible
(checked for at least CentOS 7), see
link:https://adoptium.net/installation/linux/#_centosrhelfedora_instructions[their
instructions] for specific details. This may require updated library package
versions as dependencies from the OS distribution, so you may also have to make
sure that your `/etc/yum.repos.d/*` files (certainly `CentOS-Base.repo`, maybe
also `CentOS-fasttrack.repo` and/or `CentOS-CR.repo`) to use e.g.
----
baseurl=https://vault.centos.org/centos/$releasever/os/$basearch/
----
lines if the `mirrorlist` ones do not suffice to find living mirrors (WARNING:
the `/os/` part of the URL would vary for different repository types).

Slackware Linux 15
~~~~~~~~~~~~~~~~~~
Another long-term presence in the Linux landscape, and sometimes the baseline
for appliances, the Slackware project recently hit release 15 in 2022, averaging
two years per major release.
It can be installed e.g. in a VM, using ISO images from the project site; see:
* http://www.slackware.com/ => http://www.slackware.com/getslack/ =>
https://mirrors.slackware.com/slackware/slackware-iso/slackware64-15.0-iso/
* https://slackware.nl/slackware/slackware64-current-iso/
You would have to first log in as `root` and run `cgdisk` to define partitioning
for your virtual HDD, such as the common `/boot`, `swap` and `/` Linux layout,
and run `setup` to install "everything".
Note that "out of the box" Slackware does not currently on networked package
repositories and calculated dependency trees, so one has to know exactly what
they want installed.
Third-party projects for package managers are also available, e.g.
link:https://slackpkg.org/documentation.html[`slackpkg`] => see also
https://docs.slackware.com/slackware:slackpkg and
https://slackpkg.org/stable/ :
----
:; wget https://slackpkg.org/stable/slackpkg-15.0.10-noarch-1.txz && \
installpkg slackpkg-15.0.10-noarch-1.txz
----
Uncomment a mirror from `/etc/slackpkg/mirrors` according to your location
and other preferences (or use the top-listed default), and begin with:
----
:; slackpkg update
----
Note that packages may be only installed or re-installed/upgraded as separate
explicit operations, so the procedure to bring your system into needed shape
is a bit cumbersome (and each command may by default be interactive with a
choice menu), e.g.:
----
:; for P in \
bash mc vim sudo \
; do slackpkg info "$P" || slackpkg install $P || break ; done
----
For procedures below, this is automated via `root` profile to become a
`slackpkg-install` command:
----
:; grep "slackpkg-install" ~/.profile || {
echo 'slackpkg-install() { for P in "$@" ; do echo "=== $P:"; slackpkg info "$P" || slackpkg install "$P" || break ; done; }' >> ~/.profile
}
:; . ~/.profile
----
If something has a hiccup, it suggests to look for the right name, e.g.:
----
:; slackpkg search python
----
For NUT dependencies and build tools:
----
:; slackpkg update
# Baseline toolkits:
# Note there is no cppcheck, cppunit, valgrind...
# Note clang compiler tools are part of llvm package
:; slackpkg-install \
ccache time \
coreutils diffutils \
git python3 perl curl \
make autoconf automake libtool binutils \
pkg-config \
gcc llvm
# To debug eventual core dump files, or trace programs with an IDE like
# NetBeans (perhaps remotely), you may want the GNU Debugger program:
:; slackpkg-install gdb
# For spell-checking, highly recommended if you would propose pull requests:
:; slackpkg-install aspell{,-en}
# Note there is no direct "asciidoc" nor "a2x", just the competing project
# "rubygem-asciidoctor" that NUT currently has no recipes for, so you can
# not compile man/html/pdf docs here, per the default repository. See below
# for tools from alternative repositories, which seem to work well. Man page
# compilation would require docbook-xml resources; older versions are in
# this package https://slackbuilds.org/repository/15.0/system/docbook-xml/
# and recent ones are in not-installed part of main repository:
:; slackpkg-install linuxdoc-tools
# More on Python (for NUT-Monitor UI):
:; slackpkg-install \
python-pip qt5 gettext-tools gettext
# For CGI graph generation - massive packages (X11):
:; slackpkg-install \
gd
# General dependencies:
:; slackpkg-install \
openssl openssl-solibs mozilla-nss \
libusb \
net-snmp \
neon
# Shells:
:; slackpkg-install \
bash dash ksh93
----
Some more packages are available on the side, including Java (useful
e.g. to make this environment into a fully fledged Jenkins worker).
Other common NUT dependencies absent from primary Slackware repositories
can be found and downloaded (seek `*.txz` package files, although a few
are named `*.tgz`) from here, and passed to `installpkg`:
* http://www.slackware.com/~alien/slackbuilds/openjdk17/
* http://www.slackware.com/~alien/slackbuilds/asciidoc/
* http://www.slackware.com/~alien/slackbuilds/cppunit/
* http://www.slackware.com/~alien/slackbuilds/lua/ (5.1 in "stable") and
http://www.slackware.com/~alien/slackbuilds/lua53/ (5.4 in "current"
as of Slackware 15.1 candidate in the works) -- note that LUA is not
needed for the current NUT code base, but may become needed after import
of features from forks
...and even the environment for Windows cross-builds, ancient compilers
and modern toolkits to cover all bases:
* http://www.slackware.com/~alien/slackbuilds/MinGW-w64/
* http://www.slackware.com/~alien/slackbuilds/docker/
* http://www.slackware.com/~alien/slackbuilds/gcc34/
* http://www.slackware.com/~alien/slackbuilds/gcc5/
FWIW, another "more official" but older Java package seems to be at:
* http://www.slackware.com/~alien/slackbuilds/openjdk/
* https://slackbuilds.org/repository/15.0/development/jdk/
An example routine to install the latest instance of a package could be
like this:
----
:; wget -m -l1 http://www.slackware.com/~alien/slackbuilds/asciidoc/pkg/ && \
find . -name '*.t?z'
:; installpkg ./www.slackware.com/~alien/slackbuilds/asciidoc/pkg/asciidoc-8.1.0-noarch-2.tgz
----
Note that some packages are further separated by Slackware version, e.g. with
sub-directories for `15.0` and `current`:
----
:; wget -r -l1 -nd -R gif,css,jpg,html,htm --remove-listing \
http://www.slackware.com/~alien/slackbuilds/openjdk17/pkg64/15.0/
:; installpkg openjdk17-17.0.12_7-x86_64-1alien.txz
----
Upon community members' recommendations, Sotirov's SlackPack is also considered
a reputable repository: https://sotirov-bg.net/slackpack/ and should cover most
if not all of the dependencies required for NUT building (including PowerMan,
IPMI etc.)
[NOTE]
======
If setting up a CI farm agent with builds in RAM disk, keep in mind that
default mount options for `/dev/shm` preclude script execution. Either set up
the agent in a non-standard fashion (to use another work area), or if this is
a dedicated machine -- relax the mount options in `/etc/fstab`.
Here is an example with `noexec` which we *must avoid* for such use-case:
----
:; mount | grep /dev/shm
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev,noexec,relatime,inode64)
----

FreeBSD 12.2
~~~~~~~~~~~~
NOTE: As of 2024, this version is way beyond EOL -- packages have been
removed from mirrors. A discussion at
https://forums.freebsd.org/threads/easy-upgrading-from-12-2-rel-in-2024.92695/
touches on upgrades in such situation. An alternate mirror (that worked to
bump the system to `openjdk17`, as of this writing in Nov 2024) can be found
at https://mirror.sg.gs/freebsd-pkg/FreeBSD:12:amd64/quarterly/ and written
into `/etc/pkg/FreeBSD.conf` similarly to existing `url` entry.
Note that `PATH` for builds on BSD should include `/usr/local/...`:
------
:; PATH=/usr/local/libexec/ccache:/usr/local/bin:/usr/bin:$PATH
:; export PATH
------
NOTE: You may want to reference `ccache` even before all that, as detailed
below.
------

# NOTE: At least on FreeBSD 12, system-provided crypto exists and is used
# by libnetsnmp, libneon, etc. - but is not marked as a package. Conversely,
# the openssl-1.1.1k (as of this writing) can be installed as a package into
# /usr/local/lib and then causes linking conflicts. The core system-provided
# build of openssl does include headers and is useful for NUT build "as is".
# ONLY INSTALL THIS PACKAGE IF REQUIRED (may get problems to rectify later):
:; test -e /lib/libcrypto.so -a -e /usr/lib/libssl.so || \
pkg install openssl
:; pkg install \
lua51
:; pkg install \
bash dash busybox ksh93
------
Recommended:
------
:; pkg install ccache
:; ccache-update-links
------
For compatibility with common setups on other operating systems, can symlink
`/usr/local/libexec/ccache` as `/usr/lib/ccache` and possibly add dash-number
suffixed symlinks to compiler tools (e.g. `gcc-10` beside `gcc10` installed
by package).
NOTE: For Jenkins agents, also need to `pkg install openjdk11` (17 or 21
required since autumn 2024) -- and do note its further OS configuration
suggestions for special filesystem mounts.
Due to BSD specific paths *when not using* an implementation of `pkg-config`
or `pkgconf` (so guessing of flags is left to administrator -- TBD in NUT
`m4` scripts), better use this routine to test the config/build:
----
:; ./configure --with-doc=all --with-all --with-cgi \
--without-avahi --without-powerman --without-modbus \
### CPPFLAGS="-I/usr/local/include -I/usr/include" \
### LDFLAGS="-L/usr/local/lib -L/usr/lib"
----
Note the lack of `pkg-config` also precludes `libcppunit` tests, although
they also tend to mis-compile/mis-link with GCC (while CLANG seems okay).
OpenBSD 6.5
~~~~~~~~~~~
Note that `PATH` for builds on BSD should include `/usr/local/...`:
------
:; PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:$PATH
:; export PATH
------
NOTE: You may want to reference `ccache` even before all that, as detailed
below.
OpenBSD delivers many versions of numerous packages, you should specify
your pick interactively or as part of package name (e.g. `autoconf-2.69p2`).
NOTE: For the purposes of builds with Jenkins CI agents, since summer 2022 it
requires JDK11 which was first delivered with OpenBSD 6.5. Earlier iterations
used OpenBSD 6.4 and version nuances in this document may still reflect that.
FIXME: Since autumn 2024, JDK17+ is required. Maybe time to EOL OpenBSD 6.x
workers, or to SSH into them from a nearby machine's Java agent?.. Alternately,
consider https://github.com/adoptium/jdk17/blob/master/doc/building.md
During builds, you may have to tell system dispatcher scripts which version
to use (which feels inconvenient, but on the up-side for CI -- this system
allows to test many versions of auto-tools in the same agent), e.g.:
------
:; export AUTOCONF_VERSION=2.69 AUTOMAKE_VERSION=1.13
------
To use the `ci_build.sh` don't forget `bash` which is not part of OpenBSD
base installation. It is not required for "legacy" builds arranged by just
`autogen.sh` and `configure` scripts.
NOTE: The OpenBSD 6.5 `install65.iso` installation includes a set of packages
that seems to exceed whatever is available on network mirrors; for example,
the CD image included `clang` program while it is not available to `pkg_add`,
at least not via http://ftp.netbsd.hu/mirrors/openbsd/6.5/packages/amd64/
mirror. The `gcc` version on CD image differed notably from that in the
networked repository (4.2.x vs. 4.9.x).
You may have to echo a working base URL (part before "6.5/..." into the
`/etc/installurl` file, since the old distribution is no longer served by
default site.
------
# Optionally, make the environment comfortable, e.g.:
:; pkg_add sudo bash mc wget rsync
:; pkg_add \
git curl \
gmake autoconf automake libltdl libtool \

cppcheck \
pkgconf \
gcc clang
# To debug eventual core dump files, or trace programs with an IDE like
# NetBeans (perhaps remotely), you may want the GNU Debugger program:
:; pkg_add install \
gdb
# See comments below, python version and package naming depends on distro
:; pkg_add \
python
# NOTE: For python, you may eventually have to specify a variant like this
# (numbers depending on default or additional packages of your distro):
# :; pkg_add python-2.7.15p0 py-pip
# and/or:
# :; pkg_add python-3.6.6p1 py3-pip
# although you might succeed specifying shorter names and the packager
# will offer a list of matching variants (as it does for "python" above).
# NOTE: "perl" is not currently a package, but seemingly part of base OS.
# You can find a list of what is (pre-)installed with:
# :; pkg_info | grep -Ei 'perl|python'

# you may currently require to add a `libneon.so` symlink (the package seems
# to only deliver a numbered SO library name), e.g.:
:; pkg_add neon && \
if ! test -s /usr/local/lib/libneon.so ; then
ln -s "`cd /usr/local/lib && ls -1 libneon.so.* | sort -n | tail -1`" /usr/local/lib/libneon.so
fi
# Select a LUA-5.1 (or possibly 5.2?) version
:; pkg_add \
lua
:; pkg_add \
bash dash ksh93
:; pkg_add \
