Dear all,

Can it be that the python bindings for libcomedi are not working for 
python3.x?

I tried the example on my ubuntu 24.04 (and Debian 12) and I get the 
following error:
hansan@Desk-computer:~$ python
Python 3.12.3 (main, Feb  4 2025, 14:48:35) [GCC 13.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import comedi
>>> device = comedi.comedi_open("/dev/comedi0")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'comedi' has no attribute 'comedi_open'
>>> 

This does work on older Ubuntu versions like 18.04.  Is there a way to fix 
this?

I also tried pycomedi (https://pypi.org/project/pycomedi/)  but that has 
trouble to get compiled. 

My problem looks to be similar as of Bernd Porr in 2018 
See https://groups.google.com/g/comedi_list/c/MjI7FGp_Xyw/m/J5n2dlIoBAAJ

There it was suggested that libcomedi 0.11.x would/could solve this. But 
that does not look to be the case:

hansan@Desk-computer:~$ sudo apt list --installed | grep -i comedi
libcomedi-dev/noble,now 0.11.0+5-1.1build1 amd64 [installed]
libcomedi0t64/noble,now 0.11.0+5-1.1build1 amd64 [installed]
python3-comedilib/noble,now 0.11.0+5-1.1build1 amd64 [installed]
hansan@Desk-computer:~$ uname -a
Linux Desk-computer 6.8.0-59-lowlatency #61.1-Ubuntu SMP PREEMPT_DYNAMIC 
Fri Apr 18 11:13:23 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux

 Is there a way to fix this all to use Python3 to interface with comedi 
based measurement cards ?

Kind regards,

Han
