Broken dependencies on setuptools/pycparser

• PYNQ version (e.g. v2.6): 3.1.2
• Board name (e.g. Pynq-Z2): None
• Pull request type (bug fix / new feature):
• Pull request number: None
• Description:

I tried running a project that depends on pynq on my personal computer. When doing so using uv and pip, multiple dependencies were broken by recent changes. I have NOT tried it on a board but I guess the installation would be the same.

As of setuptools 82.0.0, pkg_resources is removed. It breaks utils.py.

As of pycparser 3.0.0, the dependency on PLY was removed. It breaks pynqmicroblaze/rpc.py.

The solution would either be to lock dependencies to setuptools/pycparser, or make code changes accordingly to releases.

Hi @BapisteB

Regarding the PLY dependency issue, a workaround is to downgrade pycparser to version 2.21:

pip uninstall pycparser
pip install pycparser==2.21

For the pkg_resources error, we’re still investigating. As mentioned in issue #1537 , there are known problems when compiling PYNQ on newer Ubuntu and Python versions. We're actively working on resolving these compatibility issues.

Hi @ironmanna,

Thank you for the answer.
I should have added that right now I am working on Ubuntu 24.02 with a venv with python version 3.12.3.

I did downgrade both setuptools and pycparser as a workaround for now.
