[Mario Marietto]

Hello.

I'm trying to compile libfreenect because I want to use my kinect xbox 360 on Debian 11. I'm following the tutorial that I've found here :

https://github.com/OpenKinect/libfreenect

here :

https://itsourcecode.com/modulenotfounderror/no-module-named-numpy-core-_multiarray_umath-solved/

here :

https://github.com/lava/matplotlib-cpp/issues/46

this is what I did :

# python3 --version
Python 3.8.10

# /usr/bin/python3 --version
Python 3.8.10

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

    https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

  * The Python version is: Python3.8 from "/usr/local/bin/python3.8"
  * The NumPy version is: "1.24.2"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

libfreenect is already packaged in debian. Is there a reason you're
building from source? It seems like quite a complex package to build.
If you must, consider taking a look at the existing debian packaging for
hints.

Hello.

I have installed these packages on Debian 11 :

freenect/stable,now 1:0.5.3-2 amd64 [installed]

libfreenect-bin/stable,now 1:0.5.3-2 amd64 [installed, automatic]
libfreenect-demos/stable,now 1:0.5.3-2 amd64 [installed]
libfreenect-dev/stable,now 1:0.5.3-2 amd64 [installed]
libfreenect-doc/stable,stable,now 1:0.5.3-2 all [installed, automatic]
libfreenect0.5/stable,now 1:0.5.3-2 amd64 [installed, automatic]

What I really like to do is to choose the kinect xbox 360 as a mic. I find it very comfortable to talk without having a mic in my mouth. I can use it to send voice messages to my whatsapp and Telegram friends. I've already done the same with the kinect 2 that I have attached to my Jetson nano and it worked. But on the Jetson Nano I have installed Ubuntu 20.04. So,I would like to know...what's still missing on Debian,after having installed the packages that you see above ? Because I don't see any Xbox NUI Sensor Analog Surround 4.0 on the XFCE pulseaudio addon (instead,it is present on Ubuntu 20.04). Thanks.
