The Python 3 package contains the Python development environment.
It is useful for object-oriented programming, writing scripts,
prototyping large programs, or developing entire applications.
Approximate build time:

Required disk space:

8.50.1. Installation of Python 3
Prepare Python for compilation:
./configure --prefix=/usr \
--enable-shared \
--with-system-expat \
--with-system-ffi \
--with-ensurepip=yes \
--enable-optimizations
The meaning of the configure options:
-
--with-system-expat
-
This switch enables linking against system version of
Expat.
-
--with-system-ffi
-
This switch enables linking against system version of
libffi.
-
--with-ensurepip=yes
-
This switch enables building pip and setuptools packaging
programs.
-
--enable-optimizations
-
This switch enables stable, but expensive, optimizations.
Compile the package:
make
Running the tests at this point is not recommended. The tests are
known to hang indefinitely in the partial LFS environment. If
desired, the tests can be rerun at the end of this chapter or when
Python 3 is reinstalled in BLFS. To run the tests anyway, issue
make test.
Install the package:
make install
If desired, install the preformatted documentation:
install -v -dm755 /usr/share/doc/python-3.9.6/html
tar --strip-components=1 \
--no-same-owner \
--no-same-permissions \
-C /usr/share/doc/python-3.9.6/html \
-xvf ../python-3.9.6-docs-html.tar.bz2
The meaning of the documentation install
commands:
-
--no-same-owner
and --no-same-permissions
-
Ensure the installed files have the correct ownership and
permissions. Without these options, using tar will install the package files with
the upstream creator's values.
