Description niklas.kappel 2022-05-17 09:04:37 UTC

Description of problem:
Running the command `obabel` provided by the package `openbabel` fails because it is unable to find OpenBabel plugins.

Version-Release number of selected component (if applicable):
3.1.1

How reproducible:
Always

Steps to Reproduce:
1. `sudo dnf install openbabel`
2. `obabel -L formats`

Actual results:
```
$ obabel -L formats
==============================
*** Open Babel Error  in LoadAllPlugins
  Unable to find OpenBabel plugins. Try setting the BABEL_LIBDIR environment variable.
==============================
*** Open Babel Error  in LoadAllPlugins

formats is not a recognized plugin type. Those with instances of sub-types loaded are:
ops
```

Expected results:
obabel should list recognized file formats.

Additional info:
Trying to convert any chemical structure file results in the same "Unable to find OpenBabel plugins" error. The environment variable `BABEL_LIBDIR` is empty. Installing the `openbabel` package installed the dependencies `inchi-libs` and `openbabel-libs`.

Comment 1 Alexander Ploumistos 2022-09-27 09:30:29 UTC

I had the same issue with avogadro today, I had to run it with:
export BABEL_LIBDIR=/usr/lib64/openbabel/; avogadro2

Antonio, should the openbabel package be setting this variable upon installation? One would think that at least Open Babel's executables would be able to find these libraries.

Comment 2 Antonio T. sagitter 2022-09-27 10:44:25 UTC

This issue should be fixed in the build 3.1.1-12
https://src.fedoraproject.org/rpms/openbabel/c/36f45c5c9a6a43d32317be8075c5965f72db10e4?branch=rawhide

Comment 3 Alexander Ploumistos 2022-09-27 11:41:09 UTC

Thanks Antonio, I tested openbabel-3.1.1-12.fc36 and everything is working now, I think we can close this.

P.S.: Will you submit the F36 build to bodhi or do you want me to do that?

I'm rebuilding openbabel for f36.
