I\'m trying to create a simple kernel using Ubuntu. In the terminal I typed
ld -Ttext 0x1000 -o kernel.bin loader.o main.o Video.o
But I got
I also faced the same problem, i figured out that i am 32 bit registers(eax,ecx,edx,ebx,esp,ebp,esi,edi) insist of 64 bit registers (rax,rcx,rdx,rbx,rsp,rbp,rsi,rdi), in my 64 bit computer. Then use these command to compile my program-
nasm -felf64 hello.asm
ld hello.o
./a.out
Use 64 bits instead of 32 for your loader and compile it with the following command:
nasm -f elf64 loader.asm -o loader.o
This should solve your error
If want compile the file as 32 bits, you can use:
ld -m elf_i386 -s -o file file.o
When compiling/linking 32-bit apps on x86_64, setting emulation to elf_i386 provides the correct elf format. So, for example, if you compile an assembler app with nasm -f elf file.asm -o file.o, the link command is ld -m elf_i386 -o exename file.o
