How to get started with a new compiler/extend the existing ones?

[jgspires]

Hello, my research peers and I are trying our best to extend/create a compiler for ThingML, but after some weeks we are not really sure how to proceed. We have been using ThingML for a little over six months now and we are seeking to extend the C compiler and better comprehend how it all works under the hood.

We have read quite a bit about the Code Generation Framework and have studied the little up-to-date documentation we could find. Besides, all links related to the Code Generation Framework Eclipse bundles seem to be down. Is there anywhere we could get some extra info on how to proceed? Whether it be source code, up-to-date tutorials or tools?

I apologize if we are missing something here, all we want is for someone to hopefully point us in the right direction.

Thank you!
