Build V8 (static,monolithic) from source

STEP 1
Download depot_tools from https://storage.googleapis.com/chrome-infra/depot_tools.zip if using Windows, and extract it to a path you want.

Otherwise, get depot_tools from the git repository:

git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git

STEP 2

Add the depot_tools path into the environment variable PATH.

On windows:

set PATH=Your\Path\To\depot_tools;%PATH%
set DEPOT_TOOLS_WIN_TOOLCHAIN=0

Note

If DEPOT_TOOLS_WIN_TOOLCHAIN is not set, depot_tools will fail to build because it will try to use the google internal toolchain instead of the locally installed Visual Studio.

On linux, macos:

export PATH=Your/Path/To/depot_tools:$PATH

STEP 3

Sync and fetch v8:

cd Your/Path/To/depot_tools
gclient 

mkdir -p Your/Path/To/v8 
cd Your/Path/To/v8
fetch v8
cd v8
git checkout refs/tags/12.4.254.20
gclient sync

STEP 4

Generate build configurations:

gn gen ./out.gn/x64.release

Modify the options in out.gn/x64.release/args.gn. See Options

STEP 5

Build:

ninja -C ./out.gn/x64.release v8_monolith
