-----Original Message----- From: Sells, Fred Sent: Tuesday, August 16, 2005 5:09 PM To: python-list@python.org Subject: python oldie, SWIG newbie needs help
I've been trying all day to get a simple SWIG generated interface to a
simple (but ugly) piece of c++ code provided to us by the gov't. I've tried
google, and every variation on the examples I can think of. I'm really
under the gun to get this working and would appreciate someone showing me
the error of my ways. We're running python 2.3 redhat 9 and gcc
although the code is c++, it does not use classes and the only function I
need to access is "RugCacl".
My typical error messages are shown below and the files attached. I've
tried SWIG with and without --shadow. If my last line of the .i file is
%include rug520.cpp, I don't get an error on import, but the RugCalc
function is undefined.
$ python rug520.py
Traceback (most recent call last):
File "rug520.py", line 5, in ?
import _rug520
ImportError: /home/frsells/dll/_rug520.so: undefined symbol: RugCalc
part of the c++ code is below; the whole file was bigger than the mail
handler would accept.
#include "rug520.h"
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>
#define LINUX
char masItemVal[108][5];
void LoadValue( char * sMdsRecord, int location, int length, char *
masItemValue )
{
for ( int i=0; i<length; i++ ) masItemValue[i] = sMdsRecord[location+i];
masItemValue[length] = '\0';
}
int LoadRange()
.....
#ifdef LINUX
