1422 \`configure' configures gold 0.1 to adapt to many kinds of systems.
1423
1424 Usage: $0 [OPTION]... [VAR=VALUE]...
1425
1426 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1427 VAR=VALUE.  See below for descriptions of some of the useful variables.
1428
1429 Defaults for the options are specified in brackets.
1430
1431 Configuration:
1432   -h, --help              display this help and exit
1433       --help=short        display options specific to this package
1434       --help=recursive    display the short help of all the included packages
1435   -V, --version           display version information and exit
1436   -q, --quiet, --silent   do not print \`checking ...' messages
1437       --cache-file=FILE   cache test results in FILE [disabled]
1438   -C, --config-cache      alias for \`--cache-file=config.cache'
1439   -n, --no-create         do not create output files
1440       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1441
1442 Installation directories:
1443   --prefix=PREFIX         install architecture-independent files in PREFIX
1444                           [$ac_default_prefix]
1445   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1446                           [PREFIX]
1447
1448 By default, \`make install' will install all the files in
1449 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1450 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1451 for instance \`--prefix=\$HOME'.
1452
1453 For better control, use the options below.

1456   --bindir=DIR            user executables [EPREFIX/bin]

1531 Some influential environment variables:
1532   CC          C compiler command
1533   CFLAGS      C compiler flags
1534   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1535               nonstandard directory <lib dir>
1536   LIBS        libraries to pass to the linker, e.g. -l<library>
1537   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1538               you have headers in a nonstandard directory <include dir>
1539   CPP         C preprocessor
1540   CXX         C++ compiler command

1545   YFLAGS      The list of arguments that will be passed by default to $YACC.
1546               This script will default YFLAGS to the empty string to avoid a
1547               default value of `-d' given by some make applications.
1548   PKG_CONFIG  path to pkg-config utility
1549   PKG_CONFIG_PATH
1550               directories to add to pkg-config's search path
1551   PKG_CONFIG_LIBDIR
1552               path overriding pkg-config's built-in search path
1553   JANSSON_CFLAGS
1554               C compiler flags for JANSSON, overriding pkg-config
1555   JANSSON_LIBS
1556               linker flags for JANSSON, overriding pkg-config
1557   CXXCPP      C++ preprocessor
1558
1559 Use these variables to override the choices made by `configure' or to help
1560 it to find libraries and programs with nonstandard names/locations.
