Python-3.12.1
Python 3 の概要
Python 3 パッケージは Python 開発環境を提供します。
この環境は、オブジェクト指向プログラミング、スクリプト構築、大規模なプロトタイプ開発、一連のアプリケーション開発を可能とします。

注記
Python 3 was installed in LFS.
The only reason to rebuild it here is if optional modules are
needed, or to upgrade this package.
注記
LFS や依存パッケージが本ブックに示す最新安定バージョンでなかった場合には、BLFS
開発版においては、パッケージのビルドや処理実行が適切に行われないことがあります。

重要
If upgrading to a new Python-3 minor version (for example, from
Python-3.11.x to Python-3.12.0), you will need to reinstall any
Python3 modules you have installed. You should also reinstall
packages that generate Python3 modules including gobject-introspection-1.78.1,
libxml2-2.12.3, opencv-4.8.1, Graphviz-9.0.0 (if swig is installed).
Before you upgrade, you can get a list of modules installed with
pip3 list. The list
may be incomplete as some Python modules are not installed with
pip3, for example
the cracklib module installed by
CrackLib-2.9.11. Use ls /usr/lib/python3.minor/site-packages
for a comprehensive list.
The Python modules from LFS will also have to be reinstalled:
flit-core,
wheel,
setuptools,
meson,
MarkupSafe,
and Jinja2.

Python 3 のインストール
以下のコマンドを実行して Python 3 をビルドします。
CXX="/usr/bin/g++" \
./configure --prefix=/usr \
--enable-shared \
--with-system-expat \
--enable-optimizations &&
make
To test the result, issue LC_ALL=en_US.UTF-8 make test.
Some tests may need an Internet connection.
root ユーザーになって以下を実行します。
make install
If upgrading and the documentation has been downloaded, optionally
install it as the root user:
install -v -dm755 /usr/share/doc/python-3.12.1/html
tar --strip-components=1 \
--no-same-owner \
--no-same-permissions \
-C /usr/share/doc/python-3.12.1/html \
-xvf ../python-3.12.1-docs-html.tar.bz2
コマンド説明
CXX="/usr/bin/g++" ./configure
...: Avoid an annoying message during
configuration.
--with-system-expat: This
switch enables linking against the system version of Expat.
--with-dbmliborder=bdb:gdbm:ndbm: Use
this switch if you want to build the Python DBM Module against Berkeley DB instead of GDBM.
--enable-optimizations:
This switch enables stable, but expensive, optimizations.
--with-lto: This optional switch
enables thick Link Time Optimization. Unusually, it creates a much
larger /usr/lib/python3.12/config-3.12-<arch>-linux-gnu/libpython3.12.a
with a small increase in the time to compile Python. Run-time results do not appear to show
any benefit from doing this.
Python 3 の設定
In order for python3
to find the installed documentation, create the following version
independent symlink:
ln -svfn python-3.12.1 /usr/share/doc/python-3
and add the following environment variable to the individual user's
or system's profile:
export PYTHONDOCS=/usr/share/doc/python-3/html
パッケージ構成
インストールプログラム: 2to3 (symlink) and 2to3-3.12, idle3 (symlink) and
idle3.12, pip3 and pip3.12, pydoc3 (symlink) and pydoc3.12,
python3 (symlink) and python3.12, and python3-config (symlink),
python3.12-config
インストールライブラリ: libpython3.12.so, libpython3.so
インストールディレクトリ: /usr/include/python3.12, /usr/lib/python3.12,
