After applying your patch I get:

without your patch I get:

Hi,<br>
<br>
I am finalizing my packaging of the userspace tools for Debian. The <br>
major blocker to get this uploaded are the python bindings.<br>
I ran into the following issues:<br>
- The install path is hardcoded to <br>
/usr/local/lib/python3.12/dist-packages; this should be <br>
/usr/lib/$(pythonversion)/distpackages<br>
- setuptools is deprecated:<br>
<br>
running install<br>
/usr/lib/python3/dist-packages/setuptools/_distutils/cmd.py:66: <br>
SetuptoolsDeprecationWarning: setup.py install is deprecated.<br>

Attached you can find a patch that converts the userspace tools to use <br>
pyproject.toml. This does not work (yet), since<br>
pyproject can&#39;t deal with a header that is not in the same directory as=
 <br>
the project root:<br>
<a href=3D"https://discuss.python.org/t/include-header-above-project-root/1=
02221/3" rel=3D"noreferrer" target=3D"_blank">https://discuss.python.org/t/=
include-header-above-project-root/102221/3</a><br>
None of the solutions for this are nice; IMO the best would be to <br>
symlink/copy Gpib.h to the language/python subdirectory.<br>
Alternatively, the whole build process could be implemented in make, <br>
however that is not ideal and I&#39;d like to avoid that.<br>
I&#39;d like to ask for guidance what the project prefers; the current <br>
setuptools approach will break sooner or later (it&#39;s already deprecated=
).<br>
