`configure' configures python 3.7 to adapt to many kinds of systems.

Usage: ./configure [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print checking ...' messages --cache-file=FILE cache test results in FILE [disabled] -C, --config-cache alias for--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or `..']

Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[/usr/local]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]

By default, make install' will install all the files in/usr/local/bin', /usr/local/lib' etc. You can specify an installation prefix other than/usr/local' using --prefix', for instance--prefix=$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]
--localedir=DIR locale-dependent data [DATAROOTDIR/locale]
--mandir=DIR man documentation [DATAROOTDIR/man]
--docdir=DIR documentation root [DATAROOTDIR/doc/python]
--htmldir=DIR html documentation [DOCDIR]
--dvidir=DIR dvi documentation [DOCDIR]
--pdfdir=DIR pdf documentation [DOCDIR]
--psdir=DIR ps documentation [DOCDIR]

System types:
--build=BUILD configure for building on BUILD [guessed]
--host=HOST cross-compile to build programs to run on HOST [BUILD]
--target=TARGET configure for building compilers for TARGET [HOST]

Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-universal-archs=ARCH
select architectures for universal build ("32-bit",
"64-bit", "3-way", "intel", "intel-32", "intel-64",
or "all")
--with-framework-name=FRAMEWORK
specify an alternate name of the framework built
with --enable-framework
--without-gcc never use gcc

compile main() and link python executable with C++
compiler
--with-suffix=.exe set executable suffix
--with-pydebug build with Py_DEBUG defined
--with-assertions build with C assertions enabled
--with-lto Enable Link Time Optimization in any build. Disabled
by default.
--with-hash-algorithm=[fnv|siphash24]
select hash algorithm
--with-address-sanitizer
enable AddressSanitizer
--with-libs='lib1 ...' link against additional libs
--with-system-expat build pyexpat module using an installed expat
library
--with-system-ffi build _ctypes module using an installed ffi library
--with-system-libmpdec build _decimal module using an installed libmpdec
library
--with-tcltk-includes='-I...'
override search for Tcl and Tk include files
--with-tcltk-libs='-L...'
override search for Tcl and Tk libs
--with-dbmliborder=db1:db2:...
order to check db backends for dbm. Valid value is a
colon separated string with the backend names
ndbm',gdbm' and `bdb'.
--with(out)-doc-strings disable/enable documentation strings
--with(out)-pymalloc disable/enable specialized mallocs
--with(out)-c-locale-coercion

locale

default on supported compilers)
--with(out)-ensurepip=[=upgrade]
"install" or "upgrade" using bundled pip
--with-openssl=DIR root of the OpenSSL directory
--with-ssl-default-suites=[python|openssl|STRING]
Override default cipher suites string, python: use
Python's preferred selection (default), openssl:
leave OpenSSL's defaults untouched, STRING: use a
custom string, PROTOCOL_SSLv2 ignores the setting

Some influential environment variables:
MACHDEP name for machine-dependent library files
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
LIBS libraries to pass to the linker, e.g. -l<library>
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
you have headers in a nonstandard directory <include dir>
CPP C preprocessor
PKG_CONFIG path to pkg-config utility
PKG_CONFIG_PATH
directories to add to pkg-config's search path
PKG_CONFIG_LIBDIR
path overriding pkg-config's built-in search path

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
