About the OPNsense tools

In conjunction with src.git, ports.git and core.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 10.1 (i386 or amd64 depending on your target arch) RELEASE 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/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:

• NAME: "OPNsense" (default)
• FLAVOUR: "OpenSSL" (default), "LibreSSL"
• VERSION: a version tag (if applicable)
• CONFIG: reads the above from the specified file

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

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

A known state can be checked out, removing all unwanted files from the repository, fetching all remote updates, via:

# make checkout[-<repo_branch_or_tag>]

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>[,...]

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

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 options are:

• images: remove all available images
• obj: reset the kernel/base build directory
• kernel: remove the kernel set
• base: remove the base set
• packages: remove the packages set
• release: remove the release set
• 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
