I've just pushed a branch named "python" which contains the python
bindings. I did it a bit different than you:
- All the code from your repository was imported maintaining the
history. I would like to keep it, so I did a merge of the final import
(fast forward, but forced to contain a commit).
- Python bindings are built with autotools. This allows to easily
express the dependency with libkmod... but I'm not sure this is ideal
as opposed to having a target to explicitely calling setuptools. Any
opinion?
Then I noticed the example given in the README file doesn't work.
Neither by installing they original python-kmod package :-/
>>> import kmod
>>> km = kmod.Kmod()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'Kmod'
>>> dir(kmod)
['__builtins__', '__doc__', '__file__', '__loader__', '__name__',
'__package__', '__path__', '__version__', 'list', 'version']
The old 'python-kmod' pkg works for me:
[agrover@work ~/.../python/kmod ((fac4d09...))]$ ipython
In [1]: import kmod
In [2]: km = kmod.Kmod()
In [3]: sc = list(km.lookup("soundcore"))[0]
In [4]: sc.path
Out[4]: u'/lib/modules/3.13.6-200.fc20.x86_64/kernel/sound/soundcore.ko'
but when I try to use the new stuff:
[agrover@work ~/.../python/kmod ((fac4d09...))]$
PYTHONPATH="/home/agrover/git/kmod/libkmod/python/kmod/.libs" ipython
In [1]: import kmod
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
<ipython-input-1-ff824b795612> in <module>()
----> 1 import kmod
ImportError: dynamic module does not define init function (initkmod)
Is this what you're seeing as well?
humn... indeed. The error was obfuscated for me because in the
__init__.py you catch the exception and make it pass silently.
In the build system I was inheriting the CFLAGS from the library and
unfortunately PyMODINIT_FUNC doesn't include the visibility attribute.
Since we use -fvisibility=hidden by default, this was breaking the
module.
It's working now, though I don't like to let it as -fvisibility=default.
I just pushed the python branch again. Could you ack on it?
I'm still getting this error.

I'm sorry I'm not being more help.. maybe we could get W. Trevor King or
another Cython contributor to help us out here? I played around with it
a bit and changing "kmod.list" to "list" on the line reporting an error
in kmod.c seemed to help, and then repeating for additional errors, but
kmod.c is a generated file so that's not the actual solution.
