1183 \`configure' configures this package to adapt to many kinds of systems.
1185 Usage: $0 [OPTION]... [VAR=VALUE]...
1187 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1188 VAR=VALUE. See below for descriptions of some of the useful variables.
1190 Defaults for the options are specified in brackets.
1192 Configuration:
1193 -h, --help display this help and exit
1194 --help=short display options specific to this package
1195 --help=recursive display the short help of all the included packages
1196 -V, --version display version information and exit
1197 -q, --quiet, --silent do not print \`checking...' messages
1198 --cache-file=FILE cache test results in FILE [disabled]
1199 -C, --config-cache alias for \`--cache-file=config.cache'
1200 -n, --no-create do not create output files
1201 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1203 Installation directories:
1204 --prefix=PREFIX install architecture-independent files in PREFIX
1205 [$ac_default_prefix]
1206 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1207 [PREFIX]
1209 By default, \`make install' will install all the files in
1210 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1211 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1212 for instance \`--prefix=\$HOME'.
1214 For better control, use the options below.
1216 Fine tuning of the installation directories:
1217 --bindir=DIR user executables [EPREFIX/bin]
1218 --sbindir=DIR system admin executables [EPREFIX/sbin]
1219 --libexecdir=DIR program executables [EPREFIX/libexec]
1220 --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
1221 --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
1222 --localstatedir=DIR modifiable single-machine data [PREFIX/var]
1223 --libdir=DIR object code libraries [EPREFIX/lib]
1224 --includedir=DIR C header files [PREFIX/include]
1225 --oldincludedir=DIR C header files for non-gcc [/usr/include]
1226 --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
1227 --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
1228 --infodir=DIR info documentation [DATAROOTDIR/info]

1251 Optional Features:
1252 --disable-option-checking ignore unrecognized --enable/--with options
1253 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
1254 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1255 --enable-maintainer-mode
1256 enable make rules and dependencies not useful (and
1257 sometimes confusing) to the casual installer
1258 --enable-multilib build many library versions (default)
1259 --disable-shared don't provide a shared libgnat
1261 Optional Packages:
1262 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1263 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1264 --with-build-libsubdir=DIR Directory where to find libraries for build system
1265 --with-system-libunwind use installed libunwind
1266 --with-gcc-major-version-only
1267 use only GCC major number in filesystem paths
1269 Some influential environment variables:
1270 CC C compiler command
1271 CFLAGS C compiler flags
1272 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1273 nonstandard directory <lib dir>
1274 LIBS libraries to pass to the linker, e.g. -l<library>
1275 CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1276 you have headers in a nonstandard directory <include dir>
1278 Use these variables to override the choices made by `configure' or to help
1279 it to find libraries and programs with nonstandard names/locations.
