Typekit Package

[Aladdin-Ark]

Hi,
Actually this is a question to understand more than an issue.
I assume you already know about it.
I can not use orocos-toolchain2.8 (typegen, and orogen) anymore with ruby2.3.0 and when I checked it in the installation instruction I found you mentioned orogen is not included anymore and the installation is from rock.
But I still can not understand what should I do to build my typekits? I thought it is a problem because of my typekits was developed on old my environment and I created a new one using orocreate-pkg but still same error.

Thank you and I appreciate if there is any reference that I can use to understand
