SWIG raise Syntax error - possibly a missing semicolon

Question

I'm new to SWIG
I'm trying to make a dll wrapper for python

• Below is the content of the SWING Interface file

%module IviDCPwr
%{
#include <stdarg.h>
#include <limits.h>
#include <sys.types.h>
#include "visatype.h"
#include "visa.h"
#include "ivi.h"
#include "IviVisaType.h"
#include "IviDCPwr.h"
#include "IviDCPwrObsolete.h"
%}
%include "IviDCPwr.h"

• Below is command I use

.\swig.exe -I"C:/Program Files (x86)/IVI Foundation/IVI/Include" -I"C:\Program Files (x86)\IVI Foundation\VISA\WinNT\Include" -python "IviDCPwr.i"

• Below is result of the above command

C:\Program Files (x86)\IVI Foundation\IVI\Include\IviDCPwr.h(179) : Error: Syntax error - possibly a missing semicolon (';').

• Below is the part of IviDCPwr.h

Answer 1

This is most likely caused by the _VI_FUNC define that does not come from this file and SWIG does not know anything about it.

Add

#define _VI_FUNC

like this:

%module IviDCPwr
#define _VI_FUNC
%{
#include <stdarg.h>
#include <limits.h>
#include <sys.types.h>
#include "visatype.h"
#include "visa.h"
#include "ivi.h"
#include "IviVisaType.h"
#include "IviDCPwr.h"
#include "IviDCPwrObsolete.h"
%}
%include "IviDCPwr.h"
