Python and Swig

[gerard4143]

Has anyone one successfully compiled a C shared object for Python 2.6 using Swig?
I've been trying but I keep getting this error when I try to import - "dynamic module does not define init function (initarith)"

arith.c

int add(int a, int b)
{
      return a + b;
}

Compile lines:

swig -python -module arith arith.c

gcc -I/usr/include/python2.6 -fPIC -c arith.c arith_wrap.c

ld -shared -o arith.so arith.o arith_wrap.o

I tried several sites and tutorials but I always get the same error. So has anyone got this to work? Does anyone know what's wrong?...Thanks...Gerard4143

Does anyone know how to bring C code into Python? Any answer will be appreciated..

Got it working...Gerard4143

MyLibrary2.c

unsigned short getidt()
{
	char ch1[(sizeof (unsigned short) + sizeof(void*))];

	__asm__ __volatile__
	(
	 	"sidt	%0\n\t"
		:"=m"(ch1)
	);
	return *(unsigned short*)ch1;
}

MyLibrary2.h

unsigned short getidt();

MyLibrary2.i

%module MyLibrary2

%{
#include "MyLibrary2.h"
%}

unsigned short getidt();

And finally the compile lines:

swig -python MyLibrary2.i

gcc -fPIC -c MyLibrary2.c

gcc -fPIC -c -I/usr/include/python2.6 MyLibrary2_wrap.c

gcc -shared MyLibrary.o MyLibrary2_wrap.o _MyLibrary2.so

Start Python interrupter
import MyLibrary2
MyLibrary2.getidt()

And after those simple steps...it works.....Its too hot to be doing this...Gerard4143
