3.14.10

Install CPython 3.14.10 under $CEUADMIN/python/3.14.10 using GCC 12.5.0, OpenSSL 3.3.0-dev, SQLite 3.49.2 and libffi 3.4.2.

#!/bin/bash
set -euo pipefail

module load ceuadmin/gcc/12.5.0
module load libffi/3.4.2/gcc/alfpockh
module load openssl/3.3.0-dev
module load ceuadmin/sqlite/3.49.2

PREFIX="$CEUADMIN/python/$V"
curl -fL "https://www.python.org/ftp/python/$V/Python-$V.tar.xz" \
    -o "Python-$V.tar.xz"
tar -xf "Python-$V.tar.xz"
