我编写了可以编译的汇编代码:

as power.s -o power.o

当我链接power.o目标文件时出现问题:

ld power.o -o power

为了在64位操作系统(Ubuntu 14.04)上运行,我.code32在power.s文件的开头添加了,但是我仍然得到错误:

addl %eax, %ebx

movl $1, %eax

I have a function foo written in assembly and compiled with yasm and GCC on Linux (Ubuntu) 64-bit. It simply prints a message to stdout using puts(), here is how it looks:

section .data

message:
  db 'foo() called', 0

section .text

foo:
  push rbp
  mov rbp, rsp
  lea rdi, [rel message]
  call puts
  pop rbp
  ret

It is called by a C program compiled with GCC:

extern void foo();

int main() {
    foo(); …
