devkitPro

Hello.
I would like to learn to develop for the Nintendo DS.
I have Gentoo installed, and i read on the official wiki, that i can use pacman to pull in packages, but I'd rather not install it, because there is a reason, that it's not in the main Gentoo repo. Also the tutorial says to do other stuff too, which I'd rather not do:

Set RootDir to root (/)

I'm familiar and used to building a lot of stuff manually, so I'm prepared if this is not a walk in the park.

So my question is, what are the bare minimum repositories, that I need to build to have a toolchain?
I presume i need the following:

• https://github.com/devkitPro/libnds

• https://github.com/devkitPro/libfat

• https://github.com/devkitPro/dstools

But is there a "core" repository? I tried https://github.com/devkitPro/buildscripts, but the first thing it needs is root access, so no...
Also I saw there a gcc patch. Is that mandatory?
I'd also rather have it sitting in my user's environment only and not in the whole system.

I really would like to get this to work, but I do not want to install stuff all over the system.

We don't support users building our packages themselves, sorry. There are around 300 packages with various interdependencies that are difficult to handle without a package manager.

We do provide docker images which may suit you better.

yeah, was thinking about something similar: worst case I'll just set up some virtual machine to use as a build system with some easy out-of-the box linux distro
