sys_write doesn't print a message to the terminal

Hi guys!

I'm trying to explore GNU Assembler using this example: https://0xax.github.io/asm_1/

My code of main.s is
Quote:

.data message: .ascii "ASSEMBLY OUTPUT" .text .globl _start _start: movq $1, %rdi movq $1, %rax movq $15, %rdx movq $message, %rsi syscall movq $60, %rax movq $0, %rdi syscall

Command line preparation:

Quote:

as -g -o main.o main.s ld -o main main.o

Now, I run ./main But it doesn't print anything and terminal is waiting my next command.

What's going wrong?

In GNU Debugger numbers were successfully stored in registers.

I see result of first syscall "-14" in RAX.
