Not necessarily a problem.
I've written a dummy sausage_tree.c (just returns a null pointer).


sausage_tree.c:

#include "sausage_tree.h"

s_node *s_node_new(double offset, double range, s_node *parental)
{
~  return 0x0;
}



The command "mkoctfile opt_sausage.cc sausage_tree.c" then worked
(I changed string to std::string in opt_sausage.cc for g++ 3.3.1):


address@hidden:~/sausage$ ls
declares.h  opt_sausage.cc*  sausage_tree.c*  sausage_tree.h

address@hidden:~/sausage$ mkoctfile opt_sausage.cc sausage_tree.c

address@hidden:~/sausage$ ls
declares.h       opt_sausage.o     sausage_tree.c*  sausage_tree.o
opt_sausage.cc*  opt_sausage.oct*  sausage_tree.h

Does this work for you?
