So I've quite literally spent a good 7 hours finding out how to get
the python wrapper working for ubuntu 10.10, but it's just not
building. I'm getting the error:

have no idea where to get it because I was going to get it from the
software center, but that didn't help. If there is anyone who could
help me or point me where to download the right software to build it,
that would be much appreciated.

I have the same problem before.
You need to remove the cython from Ubuntu (which is 0.12) and download the newest version (0.14) from its website
then you should be fine.

system->administration->Synaptic Package Manager
search cython
select the one you installed and right click on it.
choose "mark for removal"
then click "apply" on the top toolbar.
or simple way
under terminal
sudo apt-get --purge remove cython

Alright so I've downloaded the Cython 0.14 and extract it and typed in
the following in the terminal:
python setup.py install
and it gave me and error saying the 'gcc' failed. Is there something
I'm missing? Sorry about this but thank you for helping

maybe missing gcc?
sudo apt-get install python-dev build-essential
and you may need
sudo python setup.py install

Well, I'm getting closer. I installed the cython 0.14 which allowed me
to build the python wrapper. But when I go to try the demo
(which I typed this)
sudo python demo_cv_async.py
I got this error:
Traceback (most recent call last):
File "demo_cv_async.py", line 2, in <module>
import freenect
ImportError: /usr/local/lib/python2.6/dist-packages/freenect.so:
undefined symbol: freenect_sync_get_video
The code has a line that uses: freenect.sync_get_video but I'm not
sure what happened. Any ideas?

You need to build the main libfreenect driver and install it. Make
the build directory, cmake .., make, sudo make install.

I built and installed the libfreenect driver and I could play the demo
using:
freenect-glview
it's just when I try to play the demo of the python wrapper, it gives
the error. Did I build one of them wrong possibly?

You guys need a recent version of Cython. Build it from source or use easy_install cython. I have several machines with 10.10 using the python drivers and it didn't require any customization.

I pushed a patch that makes Cython optional and it only uses it if it is a compatible version. Let me know if that helps.
