# Building on FreeBSD

# Install dependencies

Install dependencies with pkg.

sudo pkg install autoconf automake bash cmake coreutils docbook-xsl dpkg fakeroot findutils gettext git gmake gnugrep gnupg gsed gtar libtool libplist ncurses openssl patch perl5 pkgconf po4a python39 wget zstd

You'll also need to install triehash

wget -O triehash https://raw.githubusercontent.com/julian-klode/triehash/main/triehash.pl
gsed -i 's|#!/usr/bin/perl -w|#!/usr/bin/env perl -w|g' triehash
sudo install -m755 triehash /usr/local/bin

# Install toolchain

# Automatic install

This script (opens new window) will setup your SDKs, cctools-port with your iOS toolchain, and other dependencies needed.

To run the script

wget -qO- https://gist.githubusercontent.com/asdfugil/8d629aa1d9f5080a4c6c868b47600879/raw/d845a136b5e1d447d8bd5a042199f8a309d684ab/procursus-toolchain-fbsd.sh | bash

Then, add the following to your shell's startup file (such as ~/.profile)

export PATH=${HOME}/.local/bin:${PATH}
export GNUBINDIR=${HOME}/.local/libexec/gnubin

# Manual install

If you want to install the toolchain manually for whatever reason, begin with exporting the location where you want to install the toolchain.

export PREFIX=${HOME}/.local
# or
# export PREFIX=/usr/local

Then, create a directory of GNU binaries

COREUTILS='basename cat chgrp chmod chown chroot cksum comm cp csplit cut date dd df dir dircolors dirname du echo env expand expr factor false fmt fold groups head hostid hostname id install join kill link ln logname ls md5sum mkdir mkfifo mknod mv nice nl nohup od paste pathchk pinky pr printenv printf ptx pwd readlink rm rmdir seq sha1sum shred sleep sort split stat stty su sum sync tac tail tee test touch tr true tsort tty uname unexpand uniq unlink uptime users vdir wc who whoami yes'
OTHER_GNU_BINS='make tar sed patch find'
export GNUBINDIR="${PREFIX}/libexec/gnubin"
mkdir -p "${GNUBINDIR}"
for util in $COREUTILS $OTHER_GNU_BINS; do
        ln -sfn /usr/local/bin/g$util "${GNUBINDIR}/${util}" 
ln -sfn /usr/local/bin/grep "${GNUBINDIR}/grep"

Temporarily add it to PATH

export PATH="${GNUBINDIR}":"${PATH}"

# Building Procursus

Clone the Procursus repository

git clone --recursive https://github.com/ProcursusTeam/Procursus.git

Next, you should remove ${GNUBINDIR} from your PATH because many things in FreeBSD do not expect GNU binaries

The easiest way is to restart your shell.

Then, add this to ~/.profile or the equivalent for your shell.

# Add our toolchain to the path.
export PATH=${PREFIX}/bin:${PATH}
# This tells the Procursus makefile where to find the GNU binaries
export GNUBINDIR="${PREFIX}/libexec/gnubin"

After that, run the above commands in your current shell or restart your shell.

Then, try to build bash

cd Procursus
gmake bash-package

If the build is successful, congrats! You should now be able to compile packages from Procursus. Take note that because you're not using macOS, it's likely that some packages (particularly those that need Go, Python, and/or NodeJS) will fail to compile. You will need a macOS enabled computer to compile those.

In addition, there are a few things that you might find useful.

# Extras

# Building Go Packages

Currently unsupported.

# Building Rust Packages

If you want to build Rust packages, you'll need to install rustup and install the following targets

Installing rustup

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

# iOS arm64
rustup target add aarch64-apple-ios

# macOS arm64
rustup target add aarch64-apple-darwin

# macOS x86_64
rustup target add x86_64-apple-darwin

# Tell rust to use our toolchain
cat <<EOF >>${HOME}/.cargo/config
linker = "x86_64-apple-darwin-clang"
ar = "x86_64-apple-darwin-ar"

linker = "aarch64-apple-darwin-clang"
ar = "aarch64-apple-darwin-ar"

linker = "aarch64-apple-darwin-clang"
ar = "aarch64-apple-darwin-ar"

rustflags = ["-C", "link-args=-shared"]
