Troubles when installing python extension node

$

Hi,

I’ve building my own nodes using the python extension. I’ve been working to make them work on Windows and Linux (not tried with macOS). I’ve done two versions of the nodes, one for 4.7 and other for 5.1 (at least when trying to use the 5.1 version in KNIME 4.7, it fails and viceversa).

When installing locally the nodes in Windows 11, all run smoothly, for 4.7 and 5.1. When doing the same in Linux, for 5.1 nodes work, but for 4.7, I have the following error:

An error occurred while installing the items
session context was:(profile=KNIMEProfile, phase=org.eclipse.equinox.internal.p2.engine.phases.Install, operand=null → [R]com.pharmacelera.lib_prep.channel.bin.linux.x86_64 0.1.0.202308041348, action=org.knime.product.p2.actions.ShellExec).
ShellExec command exited non-zero exit value:

I’ve used the same build_python_extension.bat (changing environment so it call the 4.7 or 5.1 versions). In principle, I’m working on X86_64 machines. This is happening for a virtual machine I have and also for a fresh linux installation.

Any clue? Funny thing is that I want to compare my nodes with fingerprints of RDKit, but apparently right now, it will be not available till 5.1.1. Doing now with CDK in the meanwhile.

Kind regards,
Fer
