1232
1233Usage: $0 [OPTION]... [VAR=VALUE]...
1234
1235To assign environment variables (e.g., CC, CFLAGS...), specify them as
1236VAR=VALUE.  See below for descriptions of some of the useful variables.
1237
1238Defaults for the options are specified in brackets.
1239
1240Configuration:
1241  -h, --help              display this help and exit
1242      --help=short        display options specific to this package
1243      --help=recursive    display the short help of all the included packages
1244  -V, --version           display version information and exit
1245  -q, --quiet, --silent   do not print \`checking ...' messages
1246      --cache-file=FILE   cache test results in FILE [disabled]
1247  -C, --config-cache      alias for \`--cache-file=config.cache'
1248  -n, --no-create         do not create output files
1249      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1250
1251Installation directories:
1252  --prefix=PREFIX         install architecture-independent files in PREFIX
1253                          [$ac_default_prefix]
1254  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1255                          [PREFIX]
1256
1257By default, \`make install' will install all the files in
1258\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1259an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1260for instance \`--prefix=\$HOME'.
1261
1262For better control, use the options below.

1302Some influential environment variables:
1303  CC          C compiler command
1304  CFLAGS      C compiler flags
1305  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1306              nonstandard directory <lib dir>
1307  LIBS        libraries to pass to the linker, e.g. -l<library>
1308  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1309              you have headers in a nonstandard directory <include dir>
1310  CPP         C preprocessor
1311
1312Use these variables to override the choices made by `configure' or to help
1313it to find libraries and programs with nonstandard names/locations.
