568 \`configure' configures this package to adapt to many kinds of systems.
570 Usage: $0 [OPTION]... [VAR=VALUE]...
572 To assign environment variables (e.g., CC, CFLAGS...), specify them as
573 VAR=VALUE. See below for descriptions of some of the useful variables.
575 Defaults for the options are specified in brackets.
578 -h, --help display this help and exit
579 --help=short display options specific to this package
580 --help=recursive display the short help of all the included packages
581 -V, --version display version information and exit
582 -q, --quiet, --silent do not print \`checking...' messages
583 --cache-file=FILE cache test results in FILE [disabled]
584 -C, --config-cache alias for \`--cache-file=config.cache'
585 -n, --no-create do not create output files
586 --srcdir=DIR find the sources in DIR [configure dir or \`..']
591 Installation directories:
592 --prefix=PREFIX install architecture-independent files in PREFIX
594 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
597 By default, \`make install' will install all the files in
598 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
599 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
600 for instance \`--prefix=\$HOME'.
602 For better control, use the options below.
604 Fine tuning of the installation directories:
605 --bindir=DIR user executables [EPREFIX/bin]
606 --sbindir=DIR system admin executables [EPREFIX/sbin]
607 --libexecdir=DIR program executables [EPREFIX/libexec]
608 --datadir=DIR read-only architecture-independent data [PREFIX/share]
609 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
610 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
611 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
612 --libdir=DIR object code libraries [EPREFIX/lib]
613 --includedir=DIR C header files [PREFIX/include]
614 --oldincludedir=DIR C header files for non-gcc [/usr/include]
615 --infodir=DIR info documentation [PREFIX/info]
616 --mandir=DIR man documentation [PREFIX/man]
622 --program-prefix=PREFIX prepend PREFIX to installed program names
623 --program-suffix=SUFFIX append SUFFIX to installed program names
624 --program-transform-name=PROGRAM run sed PROGRAM on installed program names
627 --x-includes=DIR X include files are in DIR
628 --x-libraries=DIR X library files are in DIR
631 --build=BUILD configure for building on BUILD [guessed]
632 --host=HOST build programs to run on HOST [BUILD]

662 --with-neXtaw link with neXT Athena library
663 --with-XawPlus link with Athena-Plus library
664 --with-pkg-config{=path} enable/disable use of pkg-config
665 --with-x use the X Window System
666 --with-ncurses-wrap-prefix naming-prefix for ncurses wrapped-variables
667 --disable-rpath-hack don't add rpath options for additional libraries
669 Some influential environment variables:
670 CC C compiler command
671 CFLAGS C compiler flags
672 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
673 nonstandard directory <lib dir>
674 CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have
675 headers in a nonstandard directory <include dir>
678 Use these variables to override the choices made by `configure' or to help
679 it to find libraries and programs with nonstandard names/locations.
