How to build .oct file under cygwin?

[Kenneth Ljungh]

Hello!

I'm using cygwin 2.1.35 (also tried .34) and I'm trying to build the
example file oregonator.cc found under the examples directory that
comes with octave but I get errors during linking. I'm using the
mkoctfile script like this:

> mkoctfile -L/usr/local/lib/octave-2.1.35 -L/lib 
> -L/lib/gcc-lib/i686-pc-cygwin/2.95.3-5 -loctave -loctinterp -lcruft -lg2c 
> -ltermcap -lreadline -lkpathsea oregonator.cc

but get a lot of unresolved symbols like this:

cc1plus.exe: warning: -fPIC ignored for target (all code is position 
independent)
/usr/local/lib/octave-2.1.35/liboctinterp.a(defun.o): In function 
`install_builtin_function(octave_value_list (*)(octave_value_list const &, 
int), basic_string<char, string_char_traits<char>, 
__default_alloc_template<false, 0> > const &, basic_string<char, 
string_char_traits<char>, __default_alloc_template<false, 0> > const &, 
bool)':
/cygdrive/c/klj/filer/octave/octave-2.1.35/src/ov-builtin.h:73: undefined 
reference to `octave_allocator::alloc(unsigned int)'
/cygdrive/c/klj/filer/octave/octave-2.1.35/src/ov-builtin.h:73: undefined 
reference to `octave_allocator::free(void *, unsigned int)'
/usr/local/lib/octave-2.1.35/liboctinterp.a(defun.o): In function 
`install_dld_function(octave_value_list (*)(octave_value_list const &, int), 
basic_string<char, string_char_traits<char>, __default_alloc_template<false, 
0> > const &, octave_shlib const &, basic_string<char, 
string_char_traits<char>, __default_alloc_template<false, 0> > const &, 
bool)':

and so it continous. I'm not sure how to interpret this but could
it be that something went wrong when building liboctinterp.a?
If so, how would the correct way be?

Any help, pointers or tips is very much appreciated!
