2. Basic File Structure and CMake configuration
|
|
=================================================
|
|
|
|
As a first example we will consider the ``Hurrican::Library``
|
|
class. To export a class into Python, we must create three files:
|
|
|
|
#. ``PyLibrary.h``, defines the ``PyLibrary`` C-Struct and the functions
|
|
needed outside the module istself (mostly for ``PyHurricane.cpp``).
|
|
|
|
#. ``PyLibrary.cpp``, contains the complete wrapping of the class and
|
|
the Python type definition (``PyTypeLibrary``).
|
|
|
|
#. ``PyHurricane.cpp``, the definition of the Python module into which
|
|
the classes are registered. The module act as a ``namespace`` in
|
|
Python so it is good practice to give it the same name as it's
|
|
associated C++ namespace.
|
|
|
|
|newpage|
|
|
|
|
To build a Python module in |cmake|, use the following macro:
|
|
|
|
.. code-block:: cmake
|
|
|
|
set( pyCpps PyLibrary.cpp
|
|
PyHurricane.cpp )
|
|
set( pyIncludes hurricane/isobar/PyLibrary.h
|
|
|
|
add_python_module( "${pyCpps}"
|
|
"${pyIncludes}"
|
|
"isobar;1.0;1" # Name & version of the supporting
|
|
# shared library.
|
|
Hurricane # Name of the Python module will give:
|
|
# Hurricane.so
|
|
"${depLibs}" # List of dependency libraries.
|
|
include/coriolis2/hurricane/isobar
|
|
# Where to install the include files.
|
|
