[Swig-user] trouble compiling function for python

[Christian M. <mee...@gm...>]

Hi,

When running SWIG on this function:
http://svn.origo.ethz.ch/viewvc/sas-rigid/test/calc.c?revision=211&view=markup
with '$ swig -python calc.i'
I get no complaints from swig at all. Nice. But the compiling results in
the following errors:

gcc: src/calc_wrap.c
src/calc_wrap.c:2509: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or
‘__attribute__’ before string constant

src/calc_wrap.c -o build/temp.linux-x86_64-2.5/src/calc_wrap.o" failed
with exit status 1

and my calc.i file is

%module calcwrap

%{
  import "calc.h";
  typedef struct coordinate;
%}

typedef struct coordinate;
extern unsigned long *_pofr(double r[], coordinate coords[]);

I presume I am naive at some point. Can anybody tell me my mistake? (Or
give an example on what I need to correct?

TIA
