When you need to build Golang app. in different ubuntu version, you can use chroot. I made it for the usecase. It makes chroot environment and builds a debian file. And I made a lucid with vagrant, and installed below 3 ubuntu version debians in it. Since ZMQ library is needed for this app, only lucid debian can run in lucid VM.
1. install chroot
apt-get install dchroot
apt-get install debootstrap
2. edit chroot configuration
vi /etc/schroot/schroot.conf
[precise]

location=~/chroot/precise
priority=3
users=hello
group=hello
root-groups=root
[lucid]
description=Ubuntu lucid
location=~/chroot/lucid
priority=3
users=hello
group=hello
root-groups=root
[trusty]

location=~/chroot/trusty

users=hello
group=hello
root-groups=root
$ bash chroot.sh lucid 1.0
- 1st arg: ubuntu version precise / lucid / trusty ...
- 2nd arg: want to build version
$ bash chroot.sh precise 1.0
$ bash chroot.sh trusty 1.0
- install vagrant 4.3

- add lucid in vagrant
vagrant box add lucid64 http://files.vagrantup.com/lucid64.box
- run vm
vagrant up
vagrant@hello:/vagrant$ hello server
- open another terminal and run hello with client argument.
vagrant ssh
vagrant@hello:/vagrant$ hello client
=> it works!
- but When you install hello_precise.deb in lucid, you'll get this error!
dpkg -i hello_precise.deb
vagrant@hello:/vagrant$ hello server
=> hello: /lib/libc.so.6: version `GLIBC_2.14' not found (required by hello)
