for that you have to install some python packages.

The required packages are :

(1) python-dev

    This will include the all header file of the c which is requierd for libdmtx library e.g python.h

    sudo apt-get install python-dev

(2) git

    This will install the git which is repository

    sudo apt-get install git

(3) libdmtx-utils

    libdmtx-utils is required for the libdmtx library which includes c file and all header file

    sudo apt-get install libdmtx-utils

(4)  libdmtx-dev

    libdmtx-dev is required for the libdmtx python wrapper.

    sudo apt-get install libdmtx-dev

Now we have to setup the libdmtx library,

(1) first change the directory to

    cd /usr/share/doc/libdmtx-dev/examples/python

(2)unzip pydmtx.py.gz

    sudo gunzip pydmtx.py.gz

(3)unzip pydmtxmodule.c.gz

    sudo gunzip pydmtxmodule.c.gz

(4) installing the setup of libdmtx

    sudo python setup.py install

(5) Thats it!!

now test if the installation

run this python code in your python interpreter:

        from pydmtx import DataMatrix
        from PIL import Image


        # Write a Data Matrix barcode
        dm_write = DataMatrix()
        dm_write.encode("Hello, world!")
        dm_write.save("/home/hello.png", "png")


        # Read a Data Matrix barcode
        dm_read = DataMatrix()
        img = Image.open("/home/hello.png")


        print dm_read.decode(img.size[0], img.size[1], buffer(img.tostring()))
        print dm_read.count()
        print dm_read.message(1)
        print dm_read.stats(1)
