No Headers
May 19, 2009 at 2:52pm
Is it possible to create a program without any C/C++ Headers.
I had asked this question before also but got all answers like to look at linux source code.I don't know where to start in the source code.
Help would be appreciated.

The answers you got then are the answers you'll get now. There are no easy ways to do it. Then again, no one said writing an OS was easy.

Yes, easily, but why on earth would you want to do that? Headers provide prototypes and interfaces to all the functions you need to compile your programs.

Anyone who directs you to look at the linux source is not treating you nicely. A bootloader or OS core will not use standard headers, because they are not available at the time the program is executed. That is a very special case and you shouldn't need to emulate it.
Hope this helps.

Except his whole goal was to write a 'Hello world OS', ie emulating it is exactly what he's trying to do.

Would some assembly be required for this? And would that ASM be the core of this little app?

I just said that I was making a Hello World OS so that someone could answer my question without asking much questions.

Why, may I ask, are you asking the question again given all the help you received there? Are our answers supposed to get any better?
| It looks like you are trying to do something way over your head right now. That OS FAQ that helios posted for you is the first place to start reading. Good luck! |

Hi Ashishm1995,
I have idea to write own operation system. If we create a union it will be easy

They'll certainly need it.
Denis: If you really know what you're doing and understand just what it takes to write an OS, you'll do well to choose a different partner, because Ashishm1995 obviously doesn't know the difference between application and systems programming.
