ive always wondered about things like this, becuase operating systems seem to just evolve from themselves eg. linux is programmed under linux and windows is programmed under windows.

then how about creating Unix from scratch?? Unix was first created in Bell Lab...

 

Let's forget everything

How do you start a OS from Scratch??

 

How are you going to compile??

 

Albert

You make the libraries yourself. Then you compile.

thnx Cap'n Refsmmat!!

 

but you compile the OS source code on top of what???

Another OS. Linux grew from Minix, which it turn was derived from UNIX.

 

Of course the first OS was programmed in machine code... or pieces of paper with holes in them.

thx Silencer,

 

so if I have the windows API + Windows, can I actually create a Windows-Like OS??

 

if so, any example??

 

thx

 

Albert

so they do sort of "evolve" like i thought? so in windows case it was from BASIC machine code to dos to gui and dos to a fully fleged os? must have been alot harder for them back in the day!

I thought that Windows isn't built on top of Dos!!

windows 3.1 was. From there it evolved further.

 

To create you own version you would need the windows source code, which of course is greatly protected.

I know, Silencer,

 

but maybe you guys misunderstood me abit...

 

I mean, if I want to create a very simple OS, and create the libraries myself (from scratch, so not using any OS's API), where do I write the codes?? and where do I compile them??

 

Albert

I don't know. I guess it could be any system you like.

yeah, any OS you like, from DOS to windows to linux...

 

presumably the compiler would have to be compatable with the OS you are using, other than that its all your choice.
