undefined reference to 'kmain' ?

I've done like this

And it keep popping to my face like this

Did you name the function kmain?

I just tested it out here, works perfectly. Did you copy the code exactly?

Change your compile line to "-fno-leading-underscores" instead of "-fleading-underscores". All C functions will have been compiled with a leading underscore, so to access them properly from asm you would have had to add one there, too, e.g. "global _kmain; call _kmain". The easiest way is to change the flag.

Err, I have cross-compiler. Oh hell no, I called 'gcc', not 'i586-elf-gcc' => is that the problem ?

Did I go wrong?"

The problem solved: I should call 'i586-elf-gcc' etc instead of 'gcc'

Did anyone try: ld -T linker.ld -o kernel.bin kernel.o loader.o
rather than : ld -T linker.ld -o loader.o kernel.o
with this I get the same error
may be it will be useful for someone from Google
