Hi folks,
I'm starting to look at p4p and following this guide https://mdavidsaver.github.io/p4p/starting.html#starting <https://mdavidsaver.github.io/p4p/starting.html#starting>.
Congratulations on being perhaps the first person to try P4P with python 3.11!
I haven't yet published pre-compiled .whl files for python 3.11, so I guess
something went wrong during local compilation. Could you try the following
with a new virtualenv?
python -m virtualenv anotherenv
. anotherenv/bin/activate
python -m pip install -U pip
python -m pip install nose2
python -m pip install -v p4p
python -m nose2 p4p
This adds a '-v' which will print quite a bit of detail while building p4p
and its dependencies. Please send me the full output.
I'm running into this error.
ImportError: libpvxs.so.1.1: cannot open shared object file: No such file or directory
pip show pvxslibs
shows it's installed. Full output below.
But further inspection looks like only the info directory is installed.

I tried to uninstall and reinstall with the same result.
Tried on Fedora 37 and Rocky8 with the same result.
