Installation Instructions:

Quick-Start

On Ubuntu (GNU/Linux), you will need to install httplib2 and openssl binding. Then you can download the compressed file, unzip it and use:

sudo apt-get install python-httplib2 python-m2crypto
wget https://pyafipws.googlecode.com/archive/default.zip
unzip default.zip
cd pyafipws-default
sudo pip install -r requirements.txt

Note: M2Crypto is optional, the library will use OpenSSL directly (using subprocess)

Virtual environment (testing):

The following commands clone the repository, creates a virtualenv and install the packages there (including the latest versions of the dependencies) to avoid conflicts with other libraries:

sudo apt-get install python-dev swig python-virtualenv mercurial python-pip libssl-dev
hg clone https://code.google.com/p/pyafipws
cd pyafipws
virtualenv venv
source venv/bin/activate
pip install -r requirements.txt

Dependency installation (development):

For SOAP webservices PySimpleSOAP is needed (spin-off of this library, inspired by the PHP SOAP extension):

hg clone https://code.google.com/p/pysimplesoap/
cd pysimplesoap
hg update reingart
sudo python setup.py install

For PDF generation, you will need the PyFPDF (PHP’s FPDF library, python port):

hg clone https://code.google.com/p/pyfpdf/
cd pyfpdf
sudo python setup.py install

For the GUI app, you will need wxPython:

sudo apt-get install wxpython

PythonCard is being replaced by gui2py:

hg clone https://code.google.com/p/gui2py/
cd gui2py
sudo python setup.py install

For the WEB app, you will need web2py.

On Windows, you can see available installers released for evaluation purposes on Downloads
