linux - gcc compiling assembly on ubuntu -


on first assignment of course we've been asked try compile simple assembly file on ubuntu terminal using following line:

gcc hello.s ./a.out

here code inside file:

#this simple "hello world!" program     .section    .rodata #read data section str:    .string "hello world!\n"     ########     .text   #the beginning of code .globl  main    #the label "main" used state initial point of program     .type   main, @function # label "main" representing beginning of function main:   # main function:     pushq   %rbp        #save old frame pointer     movq    %rsp,   %rbp    #create new frame pointer      movq    $str,%rdi   #the string parameter passed printf function (remember- first parameter goes in %rdi).     movq    $0,%rax     call    printf      #calling printf after passed parameters.      #return printf:     movq    $0, %rax    #return value 0 (just in c - tell os program finished successfully)     movq    %rbp, %rsp  #restore old stack pointer - release used memory.     popq    %rbp        #restore old frame pointer (the caller function frame)     ret         #return caller function (os)

but after compilation printed on terminal:

"/usr/bin/ld: /tmp/ccm5bvmg.o: relocation r_x86_64_32s against `.rodata'       can not used when making shared object; recompile -fpic /usr/bin/ld: final link failed: nonrepresentable section on output collect2: error: ld returned 1 exit status"

i've looked on web problem , tried compile flag, still nothing.
