networking_ebpf build: Numerous build errors

[chrispsommers]

Follow-up to https://github.com/ipdk-io/ipdk/issues/295. I tried building this recipe and saw errors throughout the build process. I've attached a detailed transcript. Below is a summary. Briefly, errors appeared on the console during vagrant up, host_install.sh and make start-demo. My system is an x86 tower running Ubuntu 20.04 natively, 64G RAM, 500G SSD.

BUILD ATTEMPT

I followed instructions on https://github.com/ipdk-io/ipdk/blob/main/build/networking_ebpf/README_DOCKER.md

ON HOST

 1986  cd ipdk/build/networking_ebpf/
...
 1995  vagrant up
 1997  vagrant ssh

INSIDE VM:

vagrant@bullseye:/git/ipdk/build$ history 
    1  /git/ipdk/build/networking_ebpf/scripts/host_install.sh *
    2  cd /git/ipdk/build
    3  ./ipdk install ebpf-ubuntu2004
    4  ./ipdk build
    5  make start-demo

*Note: Step 1 above is not listed in the instructions in README_DOCKER.md. When I first followed the instructions, this caused problems further on ("No docker") etc. I read https://github.com/ipdk-io/ipdk/tree/main/build/networking_ebpf#vagrant and figured I should do "host_install.sh" See https://github.com/ipdk-io/ipdk/issues/295/

Looks like there is a permission issue. Can you please try with sudo? Ex: _sudo /git/ipdk/build/networking_ebpf/scripts/host_install.sh_

Verified the build procedure vagrant native mentioned here https://github.com/ipdk-io/ipdk/tree/main/build/networking_ebpf everything went well after adding "sudo". I will update the READEME to add the _"sudo /git/ipdk/build/networking_ebpf/scripts/hostinstall.sh".

Thanks, I confirmed sudo solves it.

Hi @vsureshkumarp, is there a workaround for remaining problems? I tried the following but it didn't help:

vagrant@bullseye:~$ sudo cp -r /root/go .
vagrant@bullseye:~$ make start-demo
make: *** No rule to make target 'start-demo'.  Stop.
