Limites de cette section

Cette section n’a pas la prétention de traiter tous les cas possibles d'installation de Python …
Le principe est d'avoir la bonne version et ses dépendances pour le module SQWarePredict.

Avant de vous lancer dans l’installation, vous devez d'abord avoir la version de dbSQWare avec SQWarePredict (v2025.01 mini) pour avoir les dépendances.

Principe

Nous allons :

• Installer Python-3.12.8
• Configurer l'environnement
• Installer les dépendances
• Paramétrer et tester SQWarePredict

Installation

Installation de Python-3.12.8

# Install Python-3.12.8
# https://www.python.org/ftp/python/3.12.8/Python-3.12.8.tgz

1 # From : root@vmsqwarebox
2 ## Pour la compil Python
3 dnf install -y zlib-devel bzip2 bzip2-devel readline-devel sqlite sqlite-devel openssl-devel xz xz-devel libffi-devel findutils ncurses-devel
