- The problem statement, all variables and given/known data:
I am trying to convert a C language program over to Sparc Assembley and I am getting Undefined first referenced
symbol in file
i3 /var/tmp//ccg4vymi.o
i4 /var/tmp//ccg4vymi.o
l0 /var/tmp//ccg4vymi.o
l1 /var/tmp//ccg4vymi.o
l2 /var/tmp//ccg4vymi.o
l3 /var/tmp//ccg4vymi.o
l4 /var/tmp//ccg4vymi.o
l5 /var/tmp//ccg4vymi.o
uinput_r /var/tmp//ccg4vymi.o
outfib /var/tmp//ccg4vymi.o
ld: fatal: Symbol referencing errors. No output written to k9
collect2: ld returned 1 exit status
I think it has something to do with how i am trying to Define my variables
define(fib1, i4) ![%fp + fib1]
define(fib2, i3) ![%fp + fib2]
define(fib3, l0) ![%fp + fib3]
define(j_r, l1) ![%fp + j_r]
define(temp_r, l2) ![%fp + temp_r]
define(userinput_r, l3) ![%fp + uinput_r]
define(final_r, l4) ![%fp + final_r]
define(max_r, l5) ![%fp + max_r]

- Relevant commands, code, scripts, algorithms:
$ m4 k9.m > k9.s
$ gcc k9.s -o k9
- The attempts at a solution (include all code and scripts):
maybe i should define my varibles like so
define(fib1, i4)
define(fib2, i3)
define(fib3, l0)
define(j_r, l1)
define(temp_r, l2)
define(userinput_r, l3)
define(final_r, l4)
define(max_r, l5)
and not in a frame pointer.
