CRC in python

The crcmod is available here: http://pypi.python.org/pypi/crcmod/1.7

Have you installed it?

The test directory under ...\crcmod-1.7\test contains two files:

examples.py
test_crcmod.py

As seen on the module page, you can verify installation using:

python test_crcmod.py

The examples.py can be executed like this:

python examples.py

To create an examples.c file using the code generator method.

Have you read the first two paragraphs on the package page?

The problem is when I tried to install it, it gives me an error:

[root@localhost ~]# python setup.py install
python: can't open file 'setup.py': [Errno 2] No such file or directory
[root@localhost ~]#

-------------------
I have tried to download the crcmod-1.6 package from the internet and i put it under the root:

[root@localhost ~]# cd /root/crcmod-1.6
[root@localhost crcmod-1.6]# make
make: *** No targets specified and no makefile found.  Stop.
[root@localhost crcmod-1.6]# ls -l

Ah.  You need to be in the untar'd directory containing the setup.py

cd /root/crcmod-1.6
python setup.py install

it gave me this error:

[root@localhost home]# cd /root/crcmod-1.6
[root@localhost crcmod-1.6]# python setup.py install
running install
error: invalid Python installation: unable to open /usr/lib/python2.6/config/Makefile (No such file or directory)
[root@localhost crcmod-1.6]#

what is the result of typing:

which python

[root@localhost crcmod-1.6]# which python
/usr/bin/python

Install python-dev (package with Python header files needed for compilation c extension modules ; you will also need c compiler ;)

Instead of this error message:

error: invalid Python installation:

I think that a more accurate and helpful one would have been:

error: incomplete or partial Python installation:

I think that mish33 is probably right in that you'll have to have a complete installation of Python 2.x in order to get the crcmod to install.
