Re: [Linux-gpib-general] Problem working with Python 3.10

[Wilhelm K. <ku...@t-...>]

Hi Chris,

I’m also using linux-gpib with Python3. To make that happen I did the 
following:
Open a terminal and go to the folder linux-gpib-4.3.5/linux-gpib-user-4.3.5
Input: /PYTHON=/usr/bin/python3 ./configure/
The messages that will then come should include the following lines:
/checking for headers required to compile python extensions... found/
and some later also:
/Python binding: yes/

If this is the case then you must compile linux-gpib again.

One remark: I also use Python-ivi from Alex Forencich to control 
gpib-devices with python, which I can highly recommend.

Good success

Wilhelm
