Generality

Limitations of this section

This section does not claim to handle all possible Python installation cases …
The principle is to have the correct version and its dependencies for the SQWarePredict module.

Before you start the installation, you must first have the version of dbSQWare with SQWarePredict (v2025.01 mini) to have the dependencies.

Principle

We are going to :

  • Install Python-3.12.8
  • Setup the environnement
  • Install dependencies
  • Setup and test SQWarePredict

Installing

Installing Python-3.12.8

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

# From : root@vmsqwarebox
## For the compilation of Python
dnf install -y zlib-devel bzip2 bzip2-devel readline-devel sqlite sqlite-devel openssl-devel xz xz-devel libffi-devel findutils ncurses-devel

# From : dbsqware@vmsqwarebox

mkdir -p $HOME/dbSQWare/SQWarePredict/python-src
mkdir -p $HOME/dbSQWare/SQWarePredict/python/3.12.8

Rsource recovery for an installation with internet access

Download the sources and put them in/tmp : 

# From : dbsqware@vmsqwarebox

cd /tmp
wget https://www.python.org/ftp/python/3.12.8/Python-3.12.8.tgz
cd $HOME/dbSQWare/SQWarePredict/python-src
tar -xzvf /tmp/Python-3.12.8.tgz

Download the source for an installation with internet access

Download sources from https://support.dbsqware.com/view.php?id=497 and put them in /tmp : 

# From : dbsqware@vmsqwarebox

cd $HOME/dbSQWare/SQWarePredict
tar -xzvf /tmp/python-src.tgz

cd python-src
tar -xzvf Python-3.12.8.tgz

Build

cd $HOME/dbSQWare/SQWarePredict/python-src/Python-3.12.8

Environnement update

Changes for ~dbsqware/.bash_profile <syntaxhighlight lang="sh" line>

  1. env Python 3.12.8 (for SQWarePredict)

export PATH=$HOME/dbSQWare/SQWarePredict/python/3.12.8/bin:$PATH export LD_LIBRARY_PATH=$HOME/dbSQWare/SQWarePredict/python/3.12.8/lib:$LD_LIBRARY_PATH </syntaxhighlight>

<syntaxhighlight lang="sh" line>

  1. on sourcve le .bash_profile

. $HOME/.bash_profile


  1. check the PATH

dbsqware@vmsqwarebox:$HOME $ type python python is $HOME/dbSQWare/SQWarePredict/python/3.12.8/bin/python

dbsqware@vmsqwarebox:$HOME $ type pip pip is $HOME/dbSQWare/SQWarePredict/python/3.12.8/bin/pip

</syntaxhighlight>

<syntaxhighlight lang="sh" line>

  1. check the versions

dbsqware@vmsqwarebox:$HOME $ python --version Python 3.12.8

dbsqware@vmsqwarebox:$HOME $ pip --version pip 24.3.1 from $HOME/dbSQWare/SQWarePredict/python/3.12.8/lib/python3.12/site-packages/pip (python 3.12)

    1. Setting up the Python env

python -m venv $HOME/dbSQWare/SQWarePredict/python/SQWarePredict-python-env-3.12.8 cd $HOME/dbSQWare/SQWarePredict/python ll SQWarePredict-python-env-3.12.8 ln -s SQWarePredict-python-env-3.12.8 SQWarePredict-python-env . $HOME/dbSQWare/SQWarePredict/python/SQWarePredict-python-env/bin/activate
