Wanting to build 16-CURRENT

[psmitty0227]

I've cloned my original Virtual-machine onto which I'd like to install FreeBSD 16-CURRENT on however, I can't seem to get a how-to that explains to me how to do-so.

Could one of the more experienced users explain the steps that one needs to take? At this point I'm willing to try anything.

You should probably try to build a -STABLE version first. Get some experience.

Thread 'Topics about unsupported FreeBSD versions'

Jun 24, 2013

The FreeBSD Forums cater primarily to end-users and systems administrators. As such, the Forums focus almost exclusively on FreeBSD versions that are officially supported according to the official FreeBSD website. Since resources are scarce, the FreeBSD Forums strongly suggest that anyone asking questions on the forums run one of the officially supported versions (see the links at the end of this post), for which the installed user base is logically the broadest.

In terms of 'unsupported versions' we make the following distinction:

1. FreeBSD versions that are...

Oh, with regards to building from source (which is what you're going to need to do);

Chapter 26. Updating and Upgrading FreeBSD

Information about how to keep a FreeBSD system up-to-date with freebsd-update or Git, how to rebuild and reinstall the entire base system, etc

docs.freebsd.org

And also build(7), src.conf(5) and make.conf(5).

Yes, yes, I know, pkgbase exist. But I believe it's good practice learning to actually build FreeBSD from source.

i you are interested this is my compile script,

cd /usr/src
git branch
git pull
make clean
make cleankernel
make cleanworld
make buildkernel  KERNCONF=MYKERNCONF -j 9
echo "DONE-KERNEL--------------------"
make buildworld  KERNCONF=MYKERNCONF -j 9
echo "DONE-WORLD---------------------"
make installkernel  KERNCONF=MYKERNCONF
etcupdate -p
make installworld  KERNCONF=MYKERNCONF
etcupdate -B
make -DBATCH_DELETE_OLD_FILES delete-old
make -DBATCH_DELETE_OLD_FILES delete-old-libs

you can build from source and still use pkgbase, you just build your own package repository instead of using make installworld.

i you are interested this is my compile script,

you should reboot after running installkernel and before running installworld. this is particularly important when running main since ABI changes can break the system if you try to run the new world on an older kernel.

also, you should rebuild ports before running delete-old-libs, otherwise it might delete libraries that are still in use.

Rebooting is for wimps.

 

[Alain De Vos]

Note i follow releng. Never had any problem. Mabye situation is different for stable/main.

 

[psmitty0227]

I'm using a completely different VM that I've just spun up for this sole purpose, so I'm not scared of hosing a perfectly functional system.

Rebooting is for wimps.

I did that yesterday morning after freebsd-update install. Now it's 15.0-RELEASE-p8.

"buildword" must be build first, then "buildkernel", to assure the toolchain to build the kernel matches the updated source tree. Otherwise it ends up using the running system toolchain.

See https://forums.freebsd.org/threads/...e-clang-version-13-0-0-for-13-1-upgrade.85393

Although I looked in the handbook, I didn't notice kernel is build after world.

The reason for that is: the toolchain (including the compiler) is part of the userland, therefore "world". It's also needed to build the kernel.

Alternatively, to build a kernel alone without "buildworld", use the kernel-toolchain target ( build(7) ).
