I'm trying to implement ptrace within my ELF but I get the undefined symbol error regarding PTRACE_ATTACH when I attempt to compile it, here's a snippet of the code.

Code:
section '.text' executable
public main
extrn  printf
extrn  ptrace
extrn  exit
main:
      ccall ptrace,PTRACE_ATTACH,mypid,0,0     


Could anyone point towards what's going wrong?

PTRACE_ATTACH is not defined.


So how would one get around this?
