Abstract

In the article Python Extensions In C++ Using SWIG, I describe how to extend Python with C++ code. That article also contains instructions for building SWIG extension DLLs on Windows. This article contains instructions for using GNU Automake and Autoconf to build SWIG extensions as shared objects on GNU/Linux.

Abstract

This article walks you through the process of writing a Python extension module in C++. To simplify the task, we are going to use SWIG to produce the “glue code” between Python and C++. The article presents the following concepts:

  • Converting between C++ and Python data types
  • Setting up an extension module project that uses SWIG
  • Using SWIG interface definition files
  • Exporting functions and classes
  • Exporting STL containers
