1257 \`configure' configures this package to adapt to many kinds of systems.
1258
1259 Usage: $0 [OPTION]... [VAR=VALUE]...
1260
1261 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1262 VAR=VALUE.  See below for descriptions of some of the useful variables.
1263
1264 Defaults for the options are specified in brackets.
1265
1266 Configuration:
1267   -h, --help              display this help and exit
1268       --help=short        display options specific to this package
1269       --help=recursive    display the short help of all the included packages
1270   -V, --version           display version information and exit
1271   -q, --quiet, --silent   do not print \`checking...' messages
1272       --cache-file=FILE   cache test results in FILE [disabled]
1273   -C, --config-cache      alias for \`--cache-file=config.cache'
1274   -n, --no-create         do not create output files
1275       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1276
1277 Installation directories:
1278   --prefix=PREFIX         install architecture-independent files in PREFIX
1279                           [$ac_default_prefix]
1280   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1281                           [PREFIX]
1282
1283 By default, \`make install' will install all the files in
1284 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1285 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1286 for instance \`--prefix=\$HOME'.
1287
1288 For better control, use the options below.

1350                           Equivalent to --with-ust-include=PATH/include
1351                           plus --with-ust-lib=PATH/lib
1352   --with-ust-include=PATH Specify directory for installed UST include files
1353   --with-ust-lib=PATH   Specify the directory for the installed UST library
1354   --with-pkgversion=PKG   Use PKG in the version string in place of "GDB"
1355   --with-bugurl=URL       Direct users to URL to report a bug
1356   --with-libthread-db=PATH
1357                           use given libthread_db directly

1359 Some influential environment variables:
1360   CC          C compiler command
1361   CFLAGS      C compiler flags
1362   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1363               nonstandard directory <lib dir>
1364   LIBS        libraries to pass to the linker, e.g. -l<library>
1365   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1366               you have headers in a nonstandard directory <include dir>
1367   CXX         C++ compiler command
1368   CXXFLAGS    C++ compiler flags
1369   CPP         C preprocessor
1370
1371 Use these variables to override the choices made by `configure' or to help
1372 it to find libraries and programs with nonstandard names/locations.
