How to build v8 as part of larger project using GN

[Ronald Fenner]

I'm using GN to build a project i'm starting on and I'm wondering ow to build v8 as part of it's source.

I've got it as a dependency in the DEPS file and paces at the root of the project like it is in chromium.

However there seems to be imports that reference gmock, various tools etc that i'd not like to have to add just to build v8 and i 

was wondering if there is a way to build it using GN like it was a standalone build and then pull the libraries in.

my BUILD.gn looks ike this at the moment

import("//build_overrides/build.gni")
import("//v8/gni/v8.gni")

executable("v8App") {
    sources = [
        "hello.cc"
    ]

    cflags = ["-Wall"]
    include_dirs=["."]
    deps = [
        "//v8:v8",
        "//v8:v8_libbase",

        "//v8:v8_libplatform",
    ]
}

I'm currently trying to get the build system setup minimal to just compile the hello sample from v8.

I do have a number of other files setup like the .gn file to set the project root.

Is there a way to potetially remap //v8 to //?

I looking into the same problem. Did you manage to find out if this is possible?

Kind regards

HI Ronald and Lars,

Here's an example of the hello world V8 embedder built with GN: https://github.com/victorgomes/v8-gn-example

The problem I was having was trying to use GN to build my project and have it build v8 as part of that project like chromium. I could build v8 separately and in fact it's what I decided to do and jus package up the libraries and then link against them in the app I'm developing.

The problem when building as like s subproject it's path references when built as a sub project pointed in the main project which work for the chromium project but meant I had to start dragging in a lot of other stuff to support v8.

I also ended switching to using hazel for the build system.
