Structure C and transform it to Python using Swig

16 New Member
Hello
I am trying to convert and manage a simple structure C ,to Python by using SWIG. The code is the following :
/* example.c*/
double sum(Vector c)
{
return c.x+c.y+c.z;
}
/*header.h*/
struct Vector{
double x,y,z;
}
/*interface_file .i*/
%module interface
%{
#include "structure. h"
%}
#include "structure. h"

I execute the following commands:
swig -python interface.i
gcc -c example.c interface_file_ wrap.c -I/usr/include/python2.5
and after that an error appears:
example.c:3: error: expected ‘)’ before ‘c’
What is the solution?

{
return c.x+c.y+c.z;
}
i think "Vector c" is a local variable, so make it as "Vector *c" and function definition as
Expand|Select|Wrap|Line Numbers
  1. double sum(Vector *c)
  2. {
  3. return (c->x+c->y+c->z);
  4. }
and call the function as

Vector a;
sum(&a);

bye

Hi- I've been searching the web for a while and I've been unable to find a way to access c data objects in python without using SWIG. I can do methods just fine but I can't access variables. It seems like PyModule_AddObject should work but it segfaults my program. There's a good chance I'm just using it wrong, or I should be using something else. Could someone give me a simple, complete example pretty please? Thanks!

Hi, I'm using Python in my win32 app by linking to the python23.dll. I'm trying to expose some c++ code in my app to Python so I can make application calls from Python scripts (according to the Python windows FAQ I shouldn't have to make a seperate dll, see link below). I create a MyModule.i file for swig which contains a simple test c++ class. I run swig on it with the following options: swig -python -c++ -includeall -shadow MyModule.i,...

I've got a C library with about 50 calls in it that I want to wrap in Python. I know I could use some tool like SWIG, but that will give me a too-literal translation; I want to make some modifications along the way to make the interface more Pythonic. For example, all of these functions return an error code (typically just errno passed along, but not always). They all accept as one of their arguments a pointer to someplace to store...

Hi, I'm trying to setup viewcvs to work with subversion 1.2.0 on Linux with Python 2.4.1. The last viewcvs (from CVS) needs subversion python bindings. I installed swig and built subversion from source with it. Everything works fine until I try to build the Python bindings. When I try "make swig-py" I get the following, Python related, error: # make swig-py

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
