[Tutor] First extension
Hello All,
I'm trying to write my first extension module, and I am getting the
following error in my command prompt and I was hoping you all could help me.
I have taken the following steps already:
1. My path is set for mingw/bin as well as python31.
2. There is a file in my disutils folder called disutils.cfg that says
[build] compiler = mingw32
3. The instructions in the 3.1 documentation state the following: "These
instructions only apply if you’re using a version of Python prior to 2.4.1
with a MinGW prior to 3.0.0 (with binutils-2.13.90-20030111-
1. http://docs.python.org/py3k/install/index.html
2. I am using Python 3.1 and the latest MinGW.
4. I tested gcc/mingw by doing C:\python31>gcc -shared pdv.c -o pdv.dll
and the test was succesful (or at least I was not given any errors while
doing the compile)
5. I searched on the internet and the closest thing I can find is the
following: http://bugs.python.org/issue4709
Below you will find the following
One, the error report
two,my setup.py file
three, the file I am trying to turn into a python extension module by
running the following two commands:

Re: [Tutor] python magazine
Well there was PyMag (http://pymag.phparch.com), each issue had a dedicated howto for a python topic. I say 'was' because they seem to busy doing something with their site, which says they'll be back by January 26th. I know it was possible to order back issues as pdf's.

I guess you can use smtplib.

I worked on the following code. It works, but not for attachments.
On the webserver I have: http://python.pastebin.com/9m8MXxuR
And inside my program I then do:
form = urllib.urlencode([("from", send_from), ("to", send_to), ("subject",
subject), ("body", body), ("attachment", attachment)])
webbrowser.open(url + "?" + form)
So, 2 questions:
- Is this a good way of sending mails over my webhost through my program?
- Attachments don't work because I'm sending the path to the file, and
ofcourse the cgi script can't find it. How should I solve this?
Cheers,
Timo
