Installation of processing

Versions earlier than Python 2.4 are not supported. If you are using Python 2.4 then you should install the ctypes package (which comes automatically with Python 2.5).

Windows binary builds for Python 2.4 and Python 2.5 are available at

http://pyprocessing.berlios.de

or

http://pypi.python.org/pypi/processing

Otherwise, if you have the correct C compiler setup then the source distribution can be installed the usual way:

python setup.py install

It should not be necessary to do any editing of setup.py if you are using Windows, Mac OS X or Linux. On other unices it may be necessary to modify the values of the macros dictionary or libraries list. The section to modify reads

else:
    macros = dict(
        HAVE_SEM_OPEN=1,
        HAVE_SEM_TIMEDWAIT=1,
        HAVE_FD_TRANSFER=1
        )
    libraries = ['rt']

More details can be found in the comments in setup.py.

Note that if you use HAVE_SEM_OPEN=0 then support for posix semaphores will not been compiled in, and then many of the functions in the processing namespace like Lock(), Queue() or will not be available. However, one can still create a manager using manager = processing.Manager() and then do lock = manager.Lock() etc.

python -m processing.tests

python -c "from processing.tests import main; main()"
