my kernel is loading but is not printing anything..
i am using grub..

Im sorry, but your description provides no clue as to why you are having this problem.

i wrote a c function to print strings on the screen...
when i booted this kernel in bochs..

it did not print anything..

if i give one print statement the system halts..
if i give more print statement then it restarts..

i have attached the file

What does bochs say before it crashes? Is that all code? how do you compile it? have you read the [wiki]Category:FAQ[/wiki] page about strings? 5)...? 6)...? 7)...? X) ...? Z)....? why is cline not set in clear_screen()?

ya. only one file..
gcc -c -m32 -B /home/vivek/os/kernel -Wall -nostdlib -nostartfiles -nostdinc -std=gnu99 *.c
as --32 startk.s -o startk.so
'ld -m elf_i386 -T linker.ld startk.so *.o -o kernel'

i use these for compilations..

bochs does not crash.. it keeps on restarting...

whats in your 'startk.s' file? Try adding a for loop after the kprint call and see what happens.

-JL

this is the main function

void main()
{
while(1);
}

but still it rebooots.
i have attached the floopy image..

sorry i could not upload the floopy image..

this is the assembly file..

including the link.ld file would be useful and in an archive would be better.

I can't see much but putting a after the "hlt" instruction might help and insert at the bottom of kmain.

Try running it with these and see what it does. If that fails use the bochs debugger to find the error.

i get undefined reference to _alloca
undefined reference to _main

when i link the files y is it????

Read the FAQ.

You need a crosscompiler.
