    How do they compile code for an OS ?

    Hi,

    HOw do you write an OS using C? OR actually how do u write os for practically ANY language? I am not asking for the details. But i was just wondering what compilers people use to compile code for an os. I thought compilers were platform-dependent, and if you're writing an OS you're creating a new platform...

    thnx

    Well, don't tell anyone, but from one os-dev'r to another:

    First, print out yor code. Doesn't matter if it's 500 pages long, print it all. Then seperate each module into its own stack, and you can optionally surround it with a securing device (rubber band). Then pick up the magical shaft of OS-Dev, and dance around the fire singing ceremonial os-dev chants to the os-dev gods. If they smile upon you, great flames should shoot up from your files, and the ashes shall form your kernel. Recompiling is a .........., though...


    Or you could go to osdev.org, but that's for sissy newbies. Now excuse me while I compile the keyboard interface ::dons ceremonial mask::

    Oh, and go to Flashdaddee's OS-dev forums is you run into any problems. We'll help you out there.

    A good one I've used is the enviroment of Keil. Used that for writing an MicrOS for M68000 and for 8051 programming.

    For PC's I think GCC will be a good one. Though note that an OS can't be completely written in C. You'll need some assembly too. I think that NASM is a good one.

    Linus Torvalds used the gcc to compile his OS (Linux).
    Of course assembly is nescessary, but the gcc also compiles assembly-code. That means that you donīt need any "NASM".

    LMAO I thought that was just funny, specially the thumbs up thing...........hey did you know that back in Roman Time the thumbs up actually meant to kill the opponent after the match was over? Yup, now you know.......well something like that, I read that online and saw it on the History Channel.....but then again you probably dont' care.

    I thought GCC originated on Linux? Or did he write GCC to compile his os?

    An OS can only be compiled by a compiler written on that OS. Conversely, a compiler can only be written on an OS compiled by that compiler.

    >the thumbs up actually meant to kill the opponent after the match was over
    Actually, there were two ways and I believe the Romans used the second. The first was thumbs up and down where down mean kill and up meant mercy. The second was a simple palm up and palm down where down meant kill and up meant mercy. I could very well be wrong about the method, but I do know that down means to kill the opponent.
