16.9 ‘configure’ Invocation
===========================

‘configure’ recognizes the following options to control how it operates.

‘--help’
‘-h’
     Print a summary of all of the options to ‘configure’, and exit.

‘--help=short’
‘--help=recursive’
     Print a summary of the options unique to this package's
     ‘configure’, and exit.  The ‘short’ variant lists options used only
     in the top level, while the ‘recursive’ variant lists options also
     present in any nested packages.

‘--version’
‘-V’
     Print the version of Autoconf used to generate the ‘configure’
     script, and exit.

‘--cache-file=FILE’
     Enable the cache: use and save the results of the tests in FILE,
     traditionally ‘config.cache’.  FILE defaults to ‘/dev/null’ to
     disable caching.

‘--config-cache’
‘-C’
     Alias for ‘--cache-file=config.cache’.

‘--srcdir=DIR’
     Look for the package's source code in directory DIR.  Usually
     ‘configure’ can determine that directory automatically.

‘--prefix=DIR’
     Use DIR as the installation prefix.  *note Installation Names:: for
     more details, including other options available for fine-tuning the
     installation locations.

‘--host=TYPE’
     Build binaries for system TYPE.  *Note System Types::.

‘--enable-FEATURE’
‘--disable-FEATURE’
     Enable or disable the optional FEATURE.  *Note Optional Features::.

‘--with-PACKAGE’
‘--without-PACKAGE’
     Use or omit PACKAGE when building.  *Note Optional Features::.

‘--quiet’
‘--silent’
‘-q’
     Do not print messages saying which checks are being made.  To
     suppress all normal output, redirect it to ‘/dev/null’ (any error
     messages will still be shown).

‘--no-create’
‘-n’
     Run the configure checks, but stop before creating any output
     files.

‘configure’ also recognizes several environment variables, and accepts
some other, less widely useful, options.  Run ‘configure --help’ for
more details.
