Strange thing with cross compiler

[NeonLightions]

Hi,
Now I'm trying to develop 64-bit OS. But I got a strange thing when compiling: When I use x86_64-elf-gcc or x86_64-elf-ld, GRUB shown this error:

When I change to system compiler, it's back to normal. Can anyone explain this for me?

Your image is broken, so we can't see the error message.

But, are you perhaps using some libc function?

Your image is broken.

I used grub-file --is-x86-multiboot2 to check the binary and there is no multiboot in binary file. So i don't think the image i broken.

The image you tried to post of the error message.

The image you tried to post of the error message.

Oh,
It said: "Multiboot header not found"

It's impossible to say what the problem is without seeing your code, your linker file, and the exact commands you are using. Can you link to an on-line repository of your code. Something in this thread may help: viewtopic.php?f=1&t=33521

Are you using multiboot or multiboot2?

I'm using multiboot2.

Here is my repo: https://github.com/NeonLightions/Amore-OS-x64. The header is at src/boot/grub/header.S, the _start function is at src/sys/_start.S and the linker is at scripts/linker.ld

That's the wrong LD. Also, you might need to use "-z max-page-size=0x1000" to tell LD that it shouldn't add a bunch of padding to your kernel.

Thank you very much! Now I can use cross linker.
