About the OPNsense tools

In conjunction with src.git, ports.git, core.git and plugins.git they create sets, packages and images for the OPNsense project. The license is a standard BSD 2-Clause as reproduced here for your convenience:

Setting up a build system

Install FreeBSD 10.2-RELEASE (i386 or amd64 depending on your target arch) on a machine with at least 10GB of hard disk (UFS works better than ZFS) and at least 2GB of RAM. All tasks require a root user. Do the following to grab the repositories (overwriting standard ports and src):

# pkg install git
# cd /usr
# rm -rf src ports
# git clone https://github.com/opnsense/plugins
# git clone https://github.com/opnsense/ports
# git clone https://github.com/opnsense/tools
# git clone https://github.com/opnsense/core
# git clone https://github.com/opnsense/src
# cd tools

TL;DR

# make everything

If successful, images can be found here: /tmp/images

Detailed build steps and options

The build is broken down into individual stages: base, kernel and ports can be built separately and repeatedly without affecting the others. All stages can be reinvoked and continue building without cleaning the previous progress. A final stage assembles all three stages into a target image.

All build steps are invoked via make(1):

# make step OPTION="value"

Available build options are:

  • CONFIG: reads the below from the specified file
  • FLAVOUR: "OpenSSL" (default), "LibreSSL"
  • MIRRORS: a list of mirrors to prefetch sets from
  • NAME: "OPNsense" (default)
  • PRIVKEY: the private key for signing sets
  • PUBKEY: the public key for signing sets
  • SETTINGS: the name of the selected settings in config/
  • TYPE: the name of the meta package to be installed
  • VERSION: a version tag (if applicable)

Build the userland binaries, bootloader and administrative files:

# make base

Build the kernel and loadable kernel modules:

# make kernel

Build all the third-party ports:

# make ports

Build additional plugins if needed:

# make plugins

Wrap up our core as a package:

# make core

A cdrom live image is created using:

# make iso

A memstick image for VGA and serial is created using:

# make memstick

A direct disk image in NanoBSD style is created using:

# make nano

About other scripts and tweaks

Before building images, you can run the regression tests to check the integrity of your core.git modifications plus generate output for the style checker:

# make regress

For very fast ports rebuilding of already installed packages the following works:

# make ports-<packagename>[,...]

For even faster ports building it may be of use to cache all distribution files before running the actual build:

# make distfiles

Compiled sets can be prefetched from a mirror, while removing any previously available set:

# make prefetch-<option>[,...] VERSION=version.to.prefetch

Available prefetch options are:

  • base: prefetch the base set
  • kernel: prefetch the kernel set
  • packages: prefetch the packages set

Core packages (pristine copies) can be batch-built using:

# make core-<repo_branch_or_tag>[,...]

Package sets (may be signed depending on whether the key is found under /root) ready for web server deployment are automatically generated and modified by ports.sh and core.sh.

Release sets can be built using:

# make release VERSION=product.version.number_revision

Kernel, base, packages and release sets are stored under /tmp/sets

All final images are stored under /tmp/images

A couple of build machine cleanup helpers are available via the clean script:

# make clean-<option>[,...]

Available clean options are:

  • base: remove the base set
  • distfiles: remove the distfiles set
  • iso: remove iso image
  • kernel: remove the kernel set
  • memstick: remove memstick images
  • nano: remove nano image
  • packages: remove the packages set
  • release: remove the release set
  • src: reset the kernel/base build directory
  • stage: reset the main staging area

The ports tree has a few of our modifications and is sometimes a bit ahead of FreeBSD. In order to keep the local changes, a skimming script is used to review and copy upstream changes:

# make skim[-<option>]

Available options are:

  • used: review and copy upstream changes
  • unused: copy unused upstream changes
  • (none): all of the above

In case a release was wrapped up, the base package list and obsoleted files need to be regenerated. This is done using:

# make rebase

Shall any debugging be needed inside the build jail, the following command will use chroot(8) to enter the active build jail:

# make chroot
