I decided against a multi level bootstrap process in NixOS because it increases the build time immensely.
In NixOS every dependent package is automatically rebuild if only the slightest change is happening in the base package.
The more levels the more complex it gets.

I don't know nothing about OpenBSD. What is the problem with packaging LDC? What makes the packaging in OpenBSD so special?

In NixOS I use LDC 0.17.6 to bootstrap the latest LDC version and then the latest LDC version to bootstrap dmd.
For now it seems that the LDC maintainers find it important to keep the bootstrapping version 0.17.x working as there are new versions every now and then.
If you want to have LDC and dmd, which is not a bad idea anyway, you are probably spending your time the most effective way possible currently.
Bootstrapping dmd with dmd doesn't have a fixed N as nobody cares really hard about the version required to build the latest version. Because of this it's quite obvious that N will grow in the near future as people might want/need newer features to implement stuff in the dmd frontend or backend.

Nothing really.  It's about the same as trying to get LDC to work on a new OS that LDC doesn't know about yet.

This is what I am doing at the moment.  It's taking time because there are OS specific items that need to be added to LDC (mainly druntime so far) for it to work on OpenBSD.

Just to bring everyone else up to speed on this. I'm currently focused on porting over LDC 0.17.6 as a bootstrap port for OpenBSD. I have a working Makefile on OpenBSD ports but the
build is currently bombing on the DRuntime build, which was expected based on conversations with the person who initially started porting this about a year ago.  I'm trying to build patches to get DRuntime to build but it is a slow process, as you can imagine.

Quick question for those in the know:
I'm working on patching sys/signal.d for this and there is a struct in here called "sigstack" that seems to need defining.  However, the struct doesn't seem to exist on OpenBSD.  Does anyone know if this struct is actually required or is there a known alternative that I can try?

Figured this out and moved on to the next batch of OpenBSD porting issues, which is currently rt/sections.d and elf related items.

FYI - If anyone is curious about the progress on this, I've push this work to the link below.  It's just the bootstrap port but it is the beginning.  And I am working on more patches which I will push to the repo below as time permits...

Made more progress but I am now trying to work on rt/sections.d and rt/sections_elf_shared.d but I am having some trouble with these. Should I be coming here for questions on these files or is there somewhere else I should go?

Thanks,
Ryan
