1218 \`configure' configures fixincludes to adapt to many kinds of systems.
1220 Usage: $0 [OPTION]... [VAR=VALUE]...
1222 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1223 VAR=VALUE. See below for descriptions of some of the useful variables.
1225 Defaults for the options are specified in brackets.
1228 -h, --help display this help and exit
1229 --help=short display options specific to this package
1230 --help=recursive display the short help of all the included packages
1231 -V, --version display version information and exit
1232 -q, --quiet, --silent do not print \`checking...' messages
1233 --cache-file=FILE cache test results in FILE [disabled]
1234 -C, --config-cache alias for \`--cache-file=config.cache'
1235 -n, --no-create do not create output files
1236 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1238 Installation directories:
1239 --prefix=PREFIX install architecture-independent files in PREFIX
1240 [$ac_default_prefix]
1241 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1244 By default, \`make install' will install all the files in
1245 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1246 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1247 for instance \`--prefix=\$HOME'.
1249 For better control, use the options below.
1251 Fine tuning of the installation directories:
1252 --bindir=DIR user executables [EPREFIX/bin]
1253 --sbindir=DIR system admin executables [EPREFIX/sbin]
1254 --libexecdir=DIR program executables [EPREFIX/libexec]

1262 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
1263 --infodir=DIR info documentation [DATAROOTDIR/info]

1291 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1292 --enable-werror-always enable -Werror despite compiler version
1293 --enable-twoprocess Use a separate process to apply the fixes
1294 --enable-maintainer-mode enable make rules and dependencies not useful
1295 (and sometimes confusing) to the casual installer
1298 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1299 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1300 --with-local-prefix=DIR specifies directory to put local include
1302 Some 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 C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1309 you have headers in a nonstandard directory <include dir>
1312 Use these variables to override the choices made by `configure' or to help
1313 it to find libraries and programs with nonstandard names/locations.
1315 Report bugs to the package provider.
