2181 \`configure' configures this package to adapt to many kinds of systems.

2183 Usage: $0 [OPTION]... [VAR=VALUE]...
2184
2185 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2186 VAR=VALUE. See below for descriptions of some of the useful variables.
2187
2188 Defaults for the options are specified in brackets.
2189
2190 Configuration:
2191 -h, --help display this help and exit
2192 --help=short display options specific to this package
2193 --help=recursive display the short help of all the included packages
2194 -V, --version display version information and exit
2195 -q, --quiet, --silent do not print \`checking...' messages
2196 --cache-file=FILE cache test results in FILE [disabled]
2197 -C, --config-cache alias for \`--cache-file=config.cache'
2198 -n, --no-create do not create output files
2199 --srcdir=DIR find the sources in DIR [configure dir or \`..']
2200
2201 Installation directories:
2202 --prefix=PREFIX install architecture-independent files in PREFIX
2203 [$ac_default_prefix]
2204 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
2205 [PREFIX]
2206
2207 By default, \`make install' will install all the files in
2208 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
2209 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2210 for instance \`--prefix=\$HOME'.
2211
2212 For better control, use the options below.
2213
2214 Fine tuning of the installation directories:
2215 --bindir=DIR user executables [EPREFIX/bin]
2216 --sbindir=DIR system admin executables [EPREFIX/sbin]
2217 --libexecdir=DIR program executables [EPREFIX/libexec]

2254 Optional Features:
2255 --disable-option-checking ignore unrecognized --enable/--with options
2256 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
2257 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
2258 --enable-maintainer-mode enable make rules and dependencies not useful
2259 (and sometimes confusing) to the casual installer
2260 --disable-largefile omit support for large files
2261 --disable-dependency-tracking speeds up one-time build
2262 --enable-dependency-tracking do not reject slow dependency extractors

2264 Some influential environment variables:
2265 CC C compiler command
2266 CFLAGS C compiler flags
2267 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
2268 nonstandard directory <lib dir>
2269 LIBS libraries to pass to the linker, e.g. -l<library>
2270 CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
2271 you have headers in a nonstandard directory <include dir>
2272 CPP C preprocessor
2273
2274 Use these variables to override the choices made by `configure' or to help
2275 it to find libraries and programs with nonstandard names/locations.
