Can't find Python.h trying to make wrapper (SOLVED)

[mikronauts]

Hi guys,

Dumb question time... where oh where is Python.h?

I tried

apt-get install python-devel

and

apt-get install python2.6-devel

no joy.

As you may guess, I have not used Python in a while - I normally work in C or assembler, however I am trying to create a python library for my "RoboPiLib" (for my RoboPi product).

I have swig compiled and installed, now I just need to build the wrapper

Thanks,

Bill

Some googling showed I should use

sudo apt-get install python-dev

but no joy, it starts to install, but there are a number of broken links.

Same for

sudo apt-get install python2.6-dev

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

I am doing a "sudo apt-get update" right now, then I will try "sudo apt-get python-dev --fix-missing".

I'll post if I get it working.

[mikronauts]

That did it!

After the apt-get update, I could apt-get install python-dev, and it installed Python.h in /usr/include/python2.7

[mikronauts]

I've been able to build my python wrapped library, and it imports fine.

Does not run yet... but that should just be debugging.

[mikronauts]

In case anyone is interested... the library works fine from Python 2.7

I still need to locate the appropriate Python.h for Python3.2, but for now I am happy with 2.7

Just for future reference you should always run an apt-get update before running apt-get install or upgrade. This ensure that the list of programs/filenames available for download is up to date and matches what is on the server. Although you probably won't need to run an update if you've already done one that day.

[mikronauts]

Thank you.

I ran apt-get update and apt-get upgrade, before that I could not even get the Python.h for 2.7

Now I'll just have to figure out the issue for 3.2, but that is less urgent as 2.7 now works with RoboPi

Try installing python3.2-dev

[mikronauts]

Thank you!

That worked right away.

A handy tip here. If you're looking for the package that a particular file is in, you can use the search function on the Debian site. Find the package it is in, then install the package of the same name from Raspbian (don't install from the Debian site).

Great tip, which will help me in the future - thanks!

In the past few years, I tended to use Ubuntu mostly due to the inclusion of non-free nVidia drivers, before that Mandrake and RedHat... but now with Pi etc I am getting more and more into Debian, and I am starting to like its more 'lean' nature.

Hi,

I understand that "sudo apt-get update" needs internet connection for updating packages.
But, do u have an idea how we can install the python3-dev by downloading them on windows machine?

For some reasons, I am not allowed to connect to Internet. .

Thank you
