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.

8.49.1. Installation of Python 3
Prepare Python for compilation:
./configure --prefix=/usr \
--enable-shared \
--with-system-expat \
--with-system-ffi \
--with-ensurepip=yes
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.
Compile the package:
make
To test the results, issue:
make test
Some tests requiring a network connection or additional packages
are skipped. The test named test_normalization is known to fail.
For more comprehensive results, the tests can be rerun when Python
3 is reinstalled in BLFS.
Install the package:
make install
If desired, install the preformatted documentation:
install -v -dm755 /usr/share/doc/python-3.9.2/html
tar --strip-components=1 \
--no-same-owner \
--no-same-permissions \
-C /usr/share/doc/python-3.9.2/html \
-xvf ../python-3.9.2-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.
