[PyQt] Compiler Error using SIP: error C3861: 'PyUnicode_FromFormat': identifier not found

[Jamie Riotto]

Hi,
I'm trying to learn to use SIP, and I've started out with a simple
Vector class. The sip file looks like this:

===========================================================================
%Module Vec3 0

class Vec3 {

%TypeHeaderCode
#include "Vec3.h"
%End

public:

	float x;
	float y;
	float z;	

	Vec3();
	Vec3(float xpos,float ypos,float zpos);
	float getX();
	float getY();
	float getZ();
	SIP_PYOBJECT __repr__() const;
%MethodCode
	sipRes = PyUnicode_FromFormat("Vec3(%f, %f, %f)", sipCpp->getX(),
sipCpp->getY(), sipCpp->getZ());
%End
};

==============================================================================

The __repr__ section is my frist attempt at implementing python
functions (operators next). I've used QPoint.h and QPoint.sip
as my starting point. The c++ code compiles ok , but when I try to
compile SIP with the following makefile,

I get the following error:

sipvec3Vec3.cpp
vec3.sip(26): error C3861: 'PyUnicode_FromFormat': identifier not found

Any suggestions? Thanks - jamie
