## Question:

Tag: ruby,gitlab,raspberry-pi2

I want to install the GitLab Runner for CI on my RPI 2 machine running Raspbian.

There is no armhf package available or mentioned on the official page: https://gitlab.com/gitlab-org/omnibus-gitlab-runner/blob/master/doc/install/README.md

and I could not find one on the net.

I've tried building it from source but it failed to make ruby 2.1.5

Tried to install it as per the follwing guide:

http://qiita.com/honeniq/items/b5c767f947725280662e

but it fails:
