Installable Python kits, and information about using Python, are available at python.org.
On Unix, Linux, BSD, macOS, and Cygwin:
./configure make make test sudo make install
This will install Python as python3.
You can pass many options to the configure script; run ./configure --help
to find out more. On macOS and Cygwin, the executable is called python.exe;
elsewhere it's just python.
If you are running on macOS with the latest updates installed, make sure to install openSSL or some other SSL software along with Homebrew or another package manager. If issues persist, see https://devguide.python.org/setup/#macos-and-os-x for more information.
On macOS, if you have configured Python with --enable-framework, you
should use make frameworkinstall to do the installation. Note that this
installs the Python executable in a place that is not normally on your PATH,
you may want to set up a symlink in /usr/local/bin.
On Windows, see PCbuild/readme.txt.
If you wish, you can create a subdirectory and invoke configure from there. For example:
mkdir debug cd debug ../configure --with-pydebug make make test
(This will fail if you also built at the top-level directory. You should do
a make clean at the toplevel first.)
To get an optimized build of Python, configure --enable-optimizations
before you run make. This sets the default make targets up to enable
Profile Guided Optimization (PGO) and may be used to auto-enable Link Time
Optimization (LTO) on some platforms. For more details, see the sections
below.
