1317 \`configure' configures LLVM 3.7.0svn to adapt to many kinds of systems.
1319 Usage: $0 [OPTION]... [VAR=VALUE]...
1321 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1322 VAR=VALUE. See below for descriptions of some of the useful variables.
1324 Defaults for the options are specified in brackets.
1327 -h, --help display this help and exit
1328 --help=short display options specific to this package
1329 --help=recursive display the short help of all the included packages
1330 -V, --version display version information and exit
1331 -q, --quiet, --silent do not print \`checking...' messages
1332 --cache-file=FILE cache test results in FILE [disabled]
1333 -C, --config-cache alias for \`--cache-file=config.cache'
1334 -n, --no-create do not create output files
1335 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1337 Installation directories:
1338 --prefix=PREFIX install architecture-independent files in PREFIX
1339 [$ac_default_prefix]
1340 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1343 By default, \`make install' will install all the files in
1344 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1345 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1346 for instance \`--prefix=\$HOME'.
1348 For better control, use the options below.
1350 Fine tuning of the installation directories:
1351 --bindir=DIR user executables [EPREFIX/bin]
1352 --sbindir=DIR system admin executables [EPREFIX/sbin]
