Presage Python binding
~~~~~~~~~~~~~~~~~~~~~~
A Python binding for Presage is automatically built when the build
system determines that the following software requirements are
satisfied:
- Python (include development headers)
- SWIG
You can optionally disable building of the python binding by passing
the --disable-python-binding flag to configure.
The Python binding is a Python extension module that wraps around the
presage library. The Python extension module is built using SWIG
and the Python Distribution Utilities package (distutils).
To use the Python binding for presage
1) Ensure that the Python extension module is enabled by checking that
./configure configuration summary reports the following:
Python binding: ............. yes
2) Build and install as usual
make
make install
3) An additional _presage library will have been built and
installed into your system Python extension library directory. This
is the presage Python extension module.
4) You should now be able to use Presage from Python. Read through the
presage_python_demo script in the bindings/python directory for an
example and try running it.
A few points to note if you installed in a non-default location:
- the Python extension module _presage.so (_presage.dll) depends
on libpresage.so (libpresage.dll), so ensure that it is on the
runtime loader path (i.e. LD_LIBRARY_PATH on Linux/Solaris, LIBPATH
on AIX, PATH on Windows, etc.)
- the Python extension module _presage.so needs to be in a standard
Python extension library directory in order for Python to find it,
or the directory containing the extension module needs to be added
to the PYTHONPATH environment variable
The presage python API is generated from the presage C++ API by SWIG.
As such, it follows SWIG conventions for mapping Python code to C++
code. A minimal description of the presage python module interface is
available from the python interpreter itself by executing:
>>> import presage
>>> help (presage)
