Hi! I hope I'm right here. I've the following assembler code:
SECTION .DATA hello: db 'Hello world!',10 helloLen: equ $-hello
SECTION .TEXT GLOBAL main
main:
; Write 'Hello world!' to the screen mov eax,4 ; 'write' system call mov ebx,1 ; file descriptor 1 = screen mov ecx,hello ; string to write mov edx,helloLen ; length of string to write int 80h ; call the kernel
; Terminate program mov eax,1 ; 'exit' system call mov ebx,0 ; exit with error code 0 int 80h ; call the kernel
Then I run:
nasm -f elf hello.asm
I link it with ld and run it:
ld -s -o hello hello.o ./hello segmentation fault
I link it with the gcc and run it:
gcc hello.o -o hello ./hello Hello world!
What's wrong with the ld?
