# dnf install git
Last metadata expiration check performed 0:00:00 ago on Mon Aug  3 13:07:23 2015.
Package git-2.4.3-3.fc22.x86_64 is already installed, skipping.
Dependencies resolved.
Nothing to do.
Complete!


Steps/procedure 


1) Depot tools can be installed as a non-root user and $PATH to include the location.

Install depot-tools as mentioned in link
http://dev.chromium.org/developers/how-tos/install-depot-tools

  1. Fetch depot_tools:
    $ git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
  2. Add depot_tools to your PATH:
    $ export PATH=`pwd`/depot_tools:"$PATH"
[arun@ ~]$ which fetch
~/workspace/gitrepo/chromedepot-tools/depot_tools/fetch

[arun@ v8]$ which gclient
~/workspace/gitrepo/chromedepot-tools/depot_tools/gclient

create a directory eg., v8engine and then execute the command: fetch v8 
2) fetch v8 
Note: this shall get v8 source code under the v8engine directory.

3) gclient sync

[arun@ v8]$ gclient sync

It took nearly an hour on my laptop for "make native" to complete.
