Hey @vanvught I am not completely sure (@peternewman can verify), but the 10.9 release may require Python 2. Can you try running each of these:

python --version
python2 --version
python3 --version
which rdm_test_server.py
python $(which rdm_test_server.py)

If you're willing to stick to Debian, there are fresh Debian packages that work with Python3 found here: https://github.com/OpenLightingProject/ola/actions/runs/4853219277 (download the ola-built-debian-bookworm-amd64 artifact). Note that these builds include the RDM tools, but the Debian APT repo builds do not yet include them. For future readers of this issue: this is a link to the build of the most recent commit to the 0.10 branch at time of writing. You can also try from the master branch: https://github.com/OpenLightingProject/ola/actions/runs/4745715644

Be sure to uninstall your compiled build first before installing the Debian packages. Also be sure to pass all of the relevent files from the downloaded archive to dpkg or apt so that it uses the local versions and not a mismatch from the APT repo.

Hi @DaAwesomeP ,

The Python 2 is not available anymore on latest Ubuntu and Debian.

Ubuntu 22.04.2

@nuc-i7:~$ python --version

Command 'python2' not found, but can be installed with:
sudo apt install python2

/usr/local/bin/rdm_test_server.py
@nuc-i7:~$ python $(which rdm_test_server.py)

The Python 2 is not available anymore on latest Ubuntu and Debian.

Yes, this is what I suspected. It seems that 10.9 does contain the Python 3 fixes but maybe it isn't installing properly with make install.

Can you try the Debian packages that I linked to? While they don't solve the issue you found, they should work because they install differently. These are official builds from this repo.

@DaAwesomeP Thank you Perry!

On Debian 12 with the *.deb files from the link above:

@vanvught Amazing! I'm glad that workaround worked for you!

We should leave this open because there seems to be an issue with how make install installs the ola dependency for Python 3.

[unitware]

any news on how to fix this manually or in the install?

Im on a Rpi4, local build of ola

$ git describe
0.10.2-3728-g653449120

$ uname -a
Linux ola 6.1.0-rpi8-rpi-v8 #1 SMP PREEMPT Debian 1:6.1.73-1+rpt1 (2024-01-25) aarch64 GNU/Linux

To make the dependencies install i used this command, note that some versions are bumped:

$  sudo apt-get install \
        libcppunit-dev \
        libcppunit-1.15-0 \
        uuid-dev \
        pkg-config \
        libncurses5-dev \
        libtool \
        autoconf \
        automake g++ \
        libmicrohttpd-dev \
        libmicrohttpd12 \
        protobuf-compiler \
        libprotobuf-lite32 \
        python3-protobuf \
        libprotobuf-dev \
        libprotoc-dev \
        zlib1g-dev \
        bison flex \
        make \
        libftdi-dev \
        libftdi1 \
        libusb-1.0-0-dev \
        liblo-dev \
        libavahi-client-dev \
        python3-numpy

Edit: I managed to workaround the install issue wich I guess confirms that it is just(tm) the install step that misses something: PYTHONPATH=/home/$USER/ola/python rdm_responder_test.py <uid>

I do get some tracebacks running the test but that is probably another issue
