Hallo there.

I know this is a very annoying error and I'm sorry for opening issue about that. I tried everything I could think of.

The error I'm getting is this one:

2.9.1

I've cloned from the branch maint-3.10 as I saw you pointed out in some other answer to work with GNU Radio 3.10:
$ git clone https://github.com/bastibl/gr-ieee802-11 --branch maint-3.10

Also python is able to correctly import module (I use asdf as version manager):

$ python
Python 3.11.3 (main, May  9 2023, 16:11:59) [GCC 11.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import ieee802_11
>>> 
$ which python
/home/dukpt/.asdf/shims/python

I've already checked issue #268, #208, #192 but none was enough. Somehow python inside GNU Radio is not able to find ieee802_11 module, even after specifying PYTHONPATH and LD_LIBRARY_PATH as I saw in other issues.

$ echo $PYTHONPATH 
/usr/lib/python3/dist-packages:/home/dukpt/.local/lib/python3.11/site-packages
$ echo $LD_LIBRARY_PATH 
/home/dukpt/.local/lib:/usr/lib:/usr/local/lib
$ ls -ld /lib
lrwxrwxrwx 1 root root 7 Mai  7 13:54 /lib -> usr/lib

/usr/local/lib/cmake/foo
/usr/local/include/foo
/usr/include/foo
/usr/lib/cmake/foo
/usr/lib/python3/dist-packages/foo

Considering what you've pointed out in previous answers:

  • incompatible versions of GNU Radio and this module - I think this was addressed by cloning the correct branch mentioned by you;
  • the install path of the Python module was not in the PYTHONPATH - done;
  • the install path of the shared library was not in LD_LIBRARY_PATH - also done;
  • the shared library was installed in a system directory and sudo ldconfig was not run - initially I had done this wrong and I thought it would work after your suggestion, however the error persisted.
  • gr-foo installed in the wrong directory - fixed

Is it possible to have some differences between main und maint-3.10 branches that could cause problems?
Or perhaps I'm still missing something?

Thank you.

Maybe you didn't build the hierarchical block, i.e., open wifi_phy_hier.grc, click build, and reopen GRC?

It's not possible to build because the gadgets are not found.

Anyway I reconfigured distro python and removed the local python managed by asdf (I think it was conflicting since gnuradio use /usr/bin/python3):
$ sudo apt install --reinstall python3 python3-minimal --fix-broken

But now I have another problem that maybe is easier to catch:

Both gr-foo and gr-ieee802_11 were configured with cmake ../ -DCMAKE_INSTALL_PREFIX=/usr

That looks like a PyBind version conflict. Can you please try the one that comes with your distro.

This shows that you have pybind11 from you package manager installed. Please also make sure that there is no other version in your user environment or some other Python package manager that may be picked up during the compilation of GNU Radio or the OOT module.

Unfortunately this is not working for me.
Do you see my PYTHONPATH and LD_LIBRARY_PATH, am I forgetting something?

Again, your output shows that you have pybind from your package manager installed. It does not show that there is not other version from asdf (or whatever you used) or pip or virtualenv or ... I'm pretty sure either GNU Radio or the OOT or both were not compiled with the correct pybind version.

Regarding pybind I already showed that it was installed from package manager and there is not other version installed:

I unalias and unsourced every asdf python reference, so both pybind and gnuradio are from package manager. I did not compile gnuradio, but installed from Ubuntu repository.

Regarding the line
-- Set runtime path of "/usr/lib/python3.10/site-packages/ieee802_11/ieee802_11_python.cpython-310-x86_64-linux-gnu.so" to ""
do you think this could indicate some reference problem?

All I can say is that I had this exact problem and it turned out to be a pybind issue.

The exact same problem is also identified as a pybind issue here: https://lists.gnu.org/archive/html/discuss-gnuradio/2021-05/msg00056.html

Please try to compile any other GNU Radio module. If other modules work, let me know. Otherwise, please write to the GNU Radio mailing list.
