The Python 3.11 package contains an older version of the Python development environment. This is only needed for building specific programs in BLFS that have not updated their build systems to support Python-3.12.2 (e.g Firefox-115.8.0, Thunderbird-115.8.0, seamonkey-2.53.18, and qtwebengine-5.15.17).
Do NOT install this package if you are not installing one of the above programs.
This package is known to build and work properly using an LFS 12.1 platform.

Install Python 3.11 by running the following commands:
CXX="/usr/bin/g++" \ ./configure --prefix=/opt/python3.11 \ --disable-shared \ --with-system-expat && make
Since this package is only used in very limited situations, tests are not recommended.
Now, as the root
user:
make install
CXX="/usr/bin/g++" ./configure ...: Avoid an annoying message during configuration.
--prefix=/opt/python3.11
:
This installs python 3.11 into /opt in order to avoid conflicts
with the system version of python, and allows for easy
removal/isolation once programs update to python3.12 or later.
--disable-shared
: This
switch disables building shared libraries. Since all the packages
that need python-3.11 have built in modules and don't directly link
to python, it is safe to turn off shared library support.
--with-system-expat
: This
switch enables linking against the system version of Expat.
