7.10.1. Installation of Python

[Note]

Note

There are two package files whose name starts with the “python” prefix. The one to extract from is Python-3.12.7.tar.xz (notice the uppercase first letter).

Prepare Python for compilation: 

./configure --prefix=/usr   \
            --enable-shared \
            --without-ensurepip

The meaning of the configure option:

--enable-shared

This switch prevents installation of static libraries.

--without-ensurepip

This switch disables the Python package installer, which is not needed at this stage.

Compile the package: 

make
[Note]

Note

Some Python 3 modules can't be built now because the dependencies are not installed yet. For the ssl module, a message Python requires a OpenSSL 1.1.1 or newer is outputted. The message should be ignored. Just make sure the toplevel make command has not failed. The optional modules are not needed now and they will be built in Chapter 8.

Install the package: 

make install

Details on this package are located in Section 8.52.2, “Contents of Python 3.”
