You probably want the main repo[0], node-v8 is unstable.

Apropos GN, we only use GYP. If you run configure in the top-level
directory, it writes out a config.gypi file and invokes tools/gyp to
create the Makefiles.

Also, I tried building your node version of V8
(https://github.com/nodejs/node-v8).. Didn't really work out very
well. What kind of massaging would I need to do to get it to cooperate
-- the gclient/gn build system that is?

Damn. There's gotta be a way to integrate freebsd support. I still
can't rap my head around the fact that no one cared to make a FreeBSD
CIPD port, or no one cared enough to add it in.

Not without manual massaging. V8 has quite a bit of platform-specific
code. If you copy over the ninja.build file verbatim, it'll try to
build a linux binary, not a freebsd binary.

We (that is, Node.js) don't build V8 standalone on anything but Linux,
although we do build it for different archs (at least x86_64 and
s390x.)

The integrated V8 build uses GYP, which we maintain, and is known to
work on FreeBSD; we have amd64 fbsd10 and 11 machines in our CI
matrix.

The relevant code is in deps/v8 and tools/gyp. You're welcome to use
that as long as you understand and accept it comes with zero
guarantees. :-)

Also, apparently they patch it, they're using V 7.0.276.38. They also
use make-v8.sh on a build machine, I'm guessing, to build it.

Re: [v8-users] Cannot build V8 with gclient/gn

[Jakob Kummerow]

Yes, the official V8 build instructions don't work on FreeBSD. That's
because nobody cared enough to make it work. Do you?

You can look at whatever Node is doing to build V8 on FreeBSD -- I believe
they have a solution. Feel free to submit a patch to the documentation (via
GitHub PR to v8.dev ) once you've figured it
out.

As for CMake/autoconf/whatever: choosing build systems is harder than most
people realize, and there are many constraints. For the time being, the
best fit for V8's needs is GN.

[v8-users] Cannot build V8 with gclient/gn

[Ethin Probst]

I followed the steps on building V8 at https://v8.dev/docs/build and 
https://v8.dev/docs/source-code, but I'm using FreeBSD and so CIPD isn't 
supported on FreeBSD. That's a huge problem because i prevents me from 
building V8 at all. Not to mention it limits me to Python 2.7 when I want 
to use Python 3.7 for the build process. Ah well.
Anyway, I run:
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
Cloning into 'depot_tools'...
remote: Sending approximately 22.24 MiB ...
remote: Total 29246 (delta 20781), reused 29246 (delta 20781)

Resolving deltas: 100% (20781/20781), done.
I then create a v8 path, set pyenv to use python 2.7.15, link v8 into my 
path, and run gclient and fetch:
$ gclient
