1337 \`configure' configures LLVM 3.8.0svn to adapt to many kinds of systems.
1339 Usage: $0 [OPTION]... [VAR=VALUE]...
1341 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1342 VAR=VALUE. See below for descriptions of some of the useful variables.
1344 Defaults for the options are specified in brackets.
1347 -h, --help display this help and exit
1348 --help=short display options specific to this package
1349 --help=recursive display the short help of all the included packages
1350 -V, --version display version information and exit
1351 -q, --quiet, --silent do not print \`checking...' messages
1352 --cache-file=FILE cache test results in FILE [disabled]
1353 -C, --config-cache alias for \`--cache-file=config.cache'
1354 -n, --no-create do not create output files
1355 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1357 Installation directories:
1358 --prefix=PREFIX install architecture-independent files in PREFIX
1359 [$ac_default_prefix]
1360 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1363 By default, \`make install' will install all the files in
1364 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1365 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1366 for instance \`--prefix=\$HOME'.
1368 For better control, use the options below.
1370 Fine tuning of the installation directories:
1371 --bindir=DIR user executables [EPREFIX/bin]
1372 --sbindir=DIR system admin executables [EPREFIX/sbin]

1512 Some influential environment variables:
1513 CC C compiler command
1514 CFLAGS C compiler flags
1515 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1516 nonstandard directory <lib dir>
1517 CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1518 you have headers in a nonstandard directory <include dir>
1519 CXX C++ compiler command
1520 CXXFLAGS C++ compiler flags
1523 Use these variables to override the choices made by `configure' or to help
1524 it to find libraries and programs with nonstandard names/locations.
