2240 --help=short display options specific to this package
2241 --help=recursive display the short help of all the included packages
2242 -V, --version display version information and exit
2243 -q, --quiet, --silent do not print \`checking...' messages
2244 --cache-file=FILE cache test results in FILE [disabled]
2245 -C, --config-cache alias for \`--cache-file=config.cache'
2246 -n, --no-create do not create output files
2247 --srcdir=DIR find the sources in DIR [configure dir or \`..']
2248
2249 Installation directories:
2250 --prefix=PREFIX install architecture-independent files in PREFIX
2251 [$ac_default_prefix]
2252 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
2253 [PREFIX]
2254
2255 By default, \`make install' will install all the files in
2256 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
2257 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2258 for instance \`--prefix=\$HOME'.
2259
2260 For better control, use the options below.

2288 --program-suffix=SUFFIX append SUFFIX to installed program names

2291 System types:

2302 Optional Features:
2303 --disable-option-checking ignore unrecognized --enable/--with options
2304 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
2305 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
2306 --enable-maintainer-mode enable make rules and dependencies not useful
2307 (and sometimes confusing) to the casual installer
2308 --disable-largefile omit support for large files
2309 --disable-dependency-tracking speeds up one-time build
2310 --enable-dependency-tracking do not reject slow dependency extractors
2311
2312 Some influential environment variables:
2313 CC C compiler command
2314 CFLAGS C compiler flags
2315 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
2316 nonstandard directory <lib dir>
2317 LIBS libraries to pass to the linker, e.g. -l<library>
2318 CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
2319 you have headers in a nonstandard directory <include dir>
2320 CPP C preprocessor
2321
2322 Use these variables to override the choices made by `configure' or to help
2323 it to find libraries and programs with nonstandard names/locations.
