Cross compiler environment using scons

Hi Team


I need to cross compile open source project opencontrail on ubuntu for ARM
using the below link..

http://juniper.github.io/contrail-vnc/README.html

The SConstruct file is as below..

*#####################################################################################################################################*

# -*- mode: python; -*-

# repository root directory
import os
import sys


sys.path.append('tools/build')

import rules
conf = Configure(DefaultEnvironment(ENV = os.environ))
env = rules.SetupBuildEnvironment(conf)

SConscript(dirs=['controller', 'vrouter', 'tools/sandesh'])

SConscript('openstack/nova_contrail_vif/SConscript',
           variant_dir='build/noarch/nova_contrail_vif')

if
os.path.exists("openstack/contrail-nova-extensions/contrail_network_api/SConscript"):

SConscript('openstack/contrail-nova-extensions/contrail_network_api/SConscript',
               variant_dir='build/noarch/contrail_nova_networkapi')

SConscript('openstack/neutron_plugin/SConscript',
           variant_dir='build/noarch/neutron_plugin')

if os.path.exists("openstack/ceilometer_plugin/SConscript"):
    SConscript('openstack/ceilometer_plugin/SConscript',
               variant_dir='build/noarch/ceilometer_plugin')

if os.path.exists("contrail-f5/SConscript"):
    SConscript('contrail-f5/SConscript',
               variant_dir='build/noarch/contrail-f5')

Whenver I'm trying to compile using command scons vrouter,it is using gcc
configuration instead of cross compiler environment.I want to know the
changes which I need to make in SConstruct file in order to use Cross
compiler.

The cross compiler are placed at path
/home/ubuntu/jain/LS2085A-SDK-20160304-yocto/build_ls2085ardb_release/tmp/sysroots/x86_64-linux/usr/bin/aarch64-fsl-linux.


Thanks
