Bonjour,

Je voudrais utiliser la reconnaissance faciale sur mon NC.

Je suis parvenu avec difficultés à installer l’extension requise pdlib mais lorsque je veux installer un modèle j’ai le message suivant

```auto
sudo -u www-data php occ face:setup -m 1
PHP Warning: PHP Startup: Unable to load dynamic library ‘pdlib.so’ (tried: /usr/lib/php/20220829/pdlib.so (/usr/lib/php/20220829/pdlib.so: cannot open shared object file: No such file or directory), /usr/lib/php/20220829/pdlib.so.so (/usr/lib/php/20220829/pdlib.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

You do not meet the dependencies to install the model 1 (Default)
Summary: The PDlib PHP extension is not loaded

```

J’ai donc copié pdlib.so vers le dossier /usr/lib/php/20220829/ et après j’ai le message suivant:

`Module compiled with module API=20210902`  
`PHP compiled with module API=20220829`  
`These options need to match`  
`in Unknown on line 0`

Quand je lance les tests de l’extension j’ai un test en fail que je ne parviens pas à résoudre.  
J’ai lu qu’il suffisait de mettre à jour la version du fichier test (update the test file tests/version.phpt to expect the updated version 1.1.0) mais ne vois pas comment faire.

```auto
Build complete.
Don’t forget to run ‘make test’.
