Question

I have problem. I have compiled file boot.o:

[BITS 16]   
[ORG 0x7C00]
[global start]
[extern _main]
start:
call _main
cli 
hlt

and compiled C++ file main.o:

 int main(){
//processes
}

Im using this LD file linker.ld for linking:

OUTPUT_FORMAT("binary")
ENTRY(start)
SECTIONS
{
. = 0x100000;

.text ALIGN(4096) :
{
    *(.text*)
    *(.gnu.linkonce.t*)
}

.rodata ALIGN(4096) :
{
    start_ctors = .;
    *(.ctor*)
    end_ctors = .;

    start_dtors = .;
    *(.dtor*)
    end_dtors = .;

    *(.rodata*)
    *(.gnu.linkonce.r*)
}

.data ALIGN(4096) :
{
    *(.data*)
    *(.gnu.linkonce.d*)
}

.bss ALIGN(4096) :
{
    *(.COMMON*)
    *(.bss*)
    *(.gnu.linkonce.b*)
}

}
So I want to start linking and I’m using g++ for windows, and I’m using this commands in cmd: ld -T linker.ld -o kernle.bin main.o boot.o. And is rejecting me error: ld: cannot preform PE operations on non PE output file kernel.bin. Does anybody know how can I repair it? Please help me.

Answer 1

Maybe -oformat bin?

And I doubt you will be able to boot it, anyway… Go read some bootloader tutorials (on osdev.org and brokenthorn.com) and you will get an answer why.
