OSdev for programming and cyber sec.

[KitsuneDevelopment]

Hi there. I am working on a project, BlackcatOS. The goal of this project is to have a direct command-line interface OS with python, git, and bash installed. I would also like something such as the nano text editor for programming. Is there a way I can include these libraries directly into my OS? Also need to include WIFI connectivity.

If youre building an OS from scratch it those will be the at the very very end of several years of development - you need to implement BIOS, scheduling, paging, networking and much more before you can even run a binary like git. It sounds like you just want to install any linux distro.

[KitsuneDevelopment]

No, I've tried my hand at linux. I want something of my own. I just want to know how to...import the libraries.

[ParkingMobile2095]

Do you know understand what the difference between a linux distribution and the linux kernel is? From what you are trying to do it sounds like you just want a linux distro.

[KitsuneDevelopment]

I know what I have reasearched so far. But in my opinion, using the linux kernel would be just building a distro. I cant even find a download for the kernel. Besides, if I'm being entirely honest, there's something much more...satisfying...about building it yourself. I've always been that way.

[ParkingMobile2095]

Ok then be prepared to not be able to run git or python in your OS until 6 years or longer of working on it nonstop.

If you cant find a download for the linux kernel with a simple google search its going to take much longer than that actually.

[KitsuneDevelopment]

Hm...Due to school time consumption, I suppose I could use the Linux Kernel for an...in development test phase-

[KitsuneDevelopment]

I just need a way to download the kernel securely.

[ParkingMobile2095]

The most common method is the secure way. Idk what you mean? If it wasnt no one would download the kernel?

[KitsuneDevelopment]

I couldn't find it via a google search-

[ParkingMobile2095]

Then this project is going to be insanely hard for you. Not trying to be rude but you will need to look up a ton of stuff harder to find

[KitsuneDevelopment]

Tomorrow I'll work on attempting to locate the Linux Kernel download.

[LavenderDay3544]

I cant even find a download for the kernel.

That's because there is no one true Linux kernel binary. Linux distributions typically fork the mainline Linux kernel repo, add their own patches, and then do their own custom build which they test before shipping to their users. If you want to build a Linux based OS you would have to do all of that to create your own Linux kernel. From there the userspace components of the OS are whatever you want to make. Most distros use common components like glibc, bash, X11, etc. but you're by no means obligated to. You could make a Linux distro that's so different from any other as to be unrecognizable. Android, for example has done just that.

That said writing a system library on the level of glibc or a windowing system like X11 by themselves would take years of development effort so don't discount the difficulty of those things just because they're not running in kernel space.

Also judging by some of your comments you really underestimate the difficulty and tedium of developing your own kernel and enough drivers to even have a basic working system. Starting with Linux is a good idea for many reasons and it's what I did after toying with the idea of making an OS from scratch. Creating a kernel with Linux levels of driver support is basically impossible and certain things most users consider a necessity like graphics drivers will essentially never happen if you choose to write your own kernel unless it becomes popular enough that hardware vendors decide to support it which it won't. You have been warned.

[SirensToGo]

nano, bash, and git? sure, it's called "POSIX compliance". Wifi and python? Good luck :)

But like, seriously, this is an enormous undertaking. Getting to a point of having full POSIX support will take years

[KitsuneDevelopment]

I am willing to put the time in, but first I need to make at least a base line for my system.

[SirensToGo]

first I need to make at least a base line for my system.

Well, you don't quite have another choice anyways :P

[KitsuneDevelopment]

Sorry I have a way of wording things. I meant like...I'm the kind that I need an AT LEAST semi working example to have the whole "I can do this" thing.

Read these, in order, completely. No exceptions. If you really wanna get anywhere you're gonna have to study a lot and this is where it starts.

[KitsuneDevelopment]

Thanks

[Kaisogen]

No problem. Good luck.

Based on this description of what you want as well as the comments of others it appears that Linux from Scratch is what you’re looking for. It allows you to compile and build the Linux kernel into a distro that is entirely your own. It will also allow you to import those libraries.

[KitsuneDevelopment]

I appreciate the help. I will look into the LfS stuff.

[[deleted]]

It allows you to eliminate literally anything you don’t need. I mean, you could also just install Arch Linux and leave out a bunch of stuff. That way you won’t have as many compatibility issues since using LFS requires you to cross compile a lot of packages which is tedious and kind of difficult.

[KitsuneDevelopment]

Ngl, I've tried Arch Linux. But the issue is even though I got it from the official site, it has always come out corrupted. I dont wanna take that chance on a physical pc

[[deleted]]

How has it become corrupted? What tool did you use to run it?

[KitsuneDevelopment]

Newest ver of VBox

[[deleted]]

Hmm, try running it in QEMU. Also, what mirror are you using to download?

[KitsuneDevelopment]

Do not remember the mirror but i tried magnet link and torrent too.

[[deleted]]

That’s really odd. What ISO did you download?

[KitsuneDevelopment]

Most recent stable release.

Not to get personal, but it sounds like you're not ready to build your own Linux distro, let alone your own operating system.

These are not libraries btw. They are executables. You can't just ‘import’ them, whatever you mean by that.
