Rajisha,
The scripts in that directory are woefully out of date.
Plesae see the vpp 18.10+ directions in
https://wiki.fd.io/view/VPP/Pulling,_Building,_Running,_Hacking_and_Pushing_VPP_Code#Building_without_virtualization
Thanks,

Hi Team,
We are trying to build VPP on ubuntu 20.04 with kernel version:5.4.x.
We cloned the gerrit code:https://gerrit.fd.io/r/vpp
When we try to build with : /build-root/vagrant/build.sh, we see below
issues:

We have seen posts on similar issue(vpp-dev@lists.fd.io | Arm build
failures on Qualcomm, ThunderX2, Mellanox Bluefield
<https://lists.fd.io/g/vpp-dev/topic/30829032?p=,,,20,0,0,0::,,,0,0,0,30829032>),but
couldn’t find a proper answer.
We tried with a stable version also, but seeing same issue.
Is there any prerequisites to build VPP on ubuntu 20.
Can anyone please share your points on this.
Regards,
Rajisha
