Prerequisites
SWIG 1.3 and GNU make are required to build modules for Python 2.4 and higher (but lower than 3). In order to build modules for Python 3.2 or higher, SWIG in version 2.0.4 or higher is required.
Note that Python 3.0 and 3.1 are not supported.
In order to build this documentation the Sphinx Python documentation generator is required.
Download
The lates source codes can be downloaded from here.
Compiling
After downloading the source code archive (this example uses ldns-1.6.13.tar.gz), pyLDNS can be enabled and compiled by typing:
> tar -xzf ldns-1.6.13.tar.gz
> cd ldns-1.6.13
> ./configure --with-pyldns
> make
You need GNU make to compile pyLDNS; SWIG and Python development libraries to compile the extension module.
Selecting Target Python Interpreter
By default, the pyLDNS module builds for the default Python interpreter (i.e., the Python interpreter which can be accessed by just typing python in the command line). If you desire to build the pyLDNS module for a different Python version then you must specify the desired Python version by setting the PYTHON_VERSION variable during the configure phase:
> PYTHON_VERSION=3.2 ./configure --with-pyldns
> make
By default the pyLDNS compiles from sources for a single Python interpreter. Remember to execute scripts requiring pyLDNS in those Python interpreters which have pyLDNS installed.
Testing
If the compilation is successful, you can test the python LDNS extension module by executing the commands:
> cd contrib/python
> make testenv
> ./ldns-mx.py
Again, remember to use the Python interpreter version which the pyLDNS module has been compiled with.
The commands will start a new shell, in which several symbolic links will be set-up. When you exit the shell, then symbolic links will be deleted.
In contrib/python/examples several simple Python scripts utilising pyLDNS can be found. These scripts demonstrate the capabilities of the LDNS library.
Installation
To install the libraries and it’s extensions type:
> cd ldns-1.6.13
> make install
