 1535Usage: $0 [OPTION]... [VAR=VALUE]...
 1536
 1537To assign environment variables (e.g., CC, CFLAGS...), specify them as
 1538VAR=VALUE.  See below for descriptions of some of the useful variables.
 1539
 1540Defaults for the options are specified in brackets.
 1541
 1542Configuration:
 1543  -h, --help              display this help and exit
 1544      --help=short        display options specific to this package
 1545      --help=recursive    display the short help of all the included packages
 1546  -V, --version           display version information and exit
 1547  -q, --quiet, --silent   do not print \`checking...' messages
 1548      --cache-file=FILE   cache test results in FILE [disabled]
 1549  -C, --config-cache      alias for \`--cache-file=config.cache'
 1550  -n, --no-create         do not create output files
 1551      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

 1556  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
 1557                          [PREFIX]
 1558
 1559By default, \`make install' will install all the files in
 1560\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 1561an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 1562for instance \`--prefix=\$HOME'.

 1724Some influential environment variables:
 1725  CC          C compiler command
 1726  CFLAGS      C compiler flags
 1727  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 1728              nonstandard directory <lib dir>
 1729  LIBS        libraries to pass to the linker, e.g. -l<library>
 1730  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
 1731              you have headers in a nonstandard directory <include dir>
 1732  CPP         C preprocessor
 1733
 1734Use these variables to override the choices made by `configure' or to help
 1735it to find libraries and programs with nonstandard names/locations.
