1334 \`configure' configures LLVM 3.4svn to adapt to many kinds of systems.
1336 Usage: $0 [OPTION]... [VAR=VALUE]...
1338 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1339 VAR=VALUE. See below for descriptions of some of the useful variables.
1341 Defaults for the options are specified in brackets.
1344 -h, --help display this help and exit
1345 --help=short display options specific to this package
1346 --help=recursive display the short help of all the included packages
1347 -V, --version display version information and exit
1348 -q, --quiet, --silent do not print \`checking...' messages
1349 --cache-file=FILE cache test results in FILE [disabled]
1350 -C, --config-cache alias for \`--cache-file=config.cache'
1351 -n, --no-create do not create output files
1352 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1354 Installation directories:
1355 --prefix=PREFIX install architecture-independent files in PREFIX
1356 [$ac_default_prefix]
1357 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1360 By default, \`make install' will install all the files in
1361 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1362 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1363 for instance \`--prefix=\$HOME'.
1365 For better control, use the options below.
1367 Fine tuning of the installation directories:
1368 --bindir=DIR user executables [EPREFIX/bin]
1369 --sbindir=DIR system admin executables [EPREFIX/sbin]
