C++ dynamically linked functions

[Kiran Kumar Sagi]

Hi,

 I am trying to call a C function from the oregonator.cc
 to get started with using C libraries in octave.

 first i tried,
  mkoctfile oregonator.cc myfunc.c
  copied the oregonator.oct file into octave bin directory.
  on using it, it breaks saying myfunc: reference symbol not found.

 next i tried creating static library from myfunc.o and tried
  mkoctfile oregonator.cc -lmyf
  it still doesnt solve the probelm.

 could you please let me know what i am missing here?

 The below is the sample oregonator.cc file.

Thanks,
kiran

#include <oct.h>

int myfunc();

DEFUN_DLD (oregonator, args, ,
  "The `oregonator'.\n\

{
  int i;
  ColumnVector dx (3);

  ColumnVector x = args(0).vector_value ();

  dx(0) = 77.27 * (x(1) - x(0)*x(1) + x(0) - 8.375e-06*pow (x(0), 2));
  dx(1) = (x(2) - x(0)*x(1) - x(1)) / 77.27;
  dx(2) = 0.161*(x(0) - x(2));
  i = myfunc();
  printf("i %d\n",i);
  return octave_value (dx);
}
