如何才能把这个简单的汇编程序编译通过并成功运行

WSL Ubuntu18.04
gcc version 7.4.0 (Ubuntu 7.4.0-1ubuntu1~18.04.1)

.section .rodata

msg:

   .ascii "Hello, world.\n"



.section .text

.globl main

main:

   movl  $4,    %eax

   movl  $1,    %ebx

   movl  $msg,  %ecx

   movl  $14,   %edx

   int   $0x80



   movl  $1, %eax

   movl  $0, %ebx

   int   $0x80

1. 不加任何选项，是这样的

$ gcc hello.s

/usr/bin/ld: /tmp/ccjICv40.o: relocation R_X86_64_32 against `.data' can not be used when making a PIE object; recompile with -fPIC

/usr/bin/ld: final link failed: Nonrepresentable section on output

collect2: error: ld returned 1 exit status

2. 加-no-pie选项后是这样的

gcc -no-pie hello.s

wj@wj:~/study/asm$ ./a.out

Segmentation fault (core dumped)

可这明明是个简单的程序，不会有段错误的啊

我向学写汇编，怎么就这么难啊
