1437      --cache-file=FILE   cache test results in FILE [disabled]
1438  -C, --config-cache      alias for \`--cache-file=config.cache'
1439  -n, --no-create         do not create output files

1442Installation directories:
1443  --prefix=PREFIX         install architecture-independent files in PREFIX
1444                          [$ac_default_prefix]
1445  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1446                          [PREFIX]
1447
1448By default, \`make install' will install all the files in
1449\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1450an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1451for instance \`--prefix=\$HOME'.
1452
1453For better control, use the options below.

1524Some influential environment variables:
1525  CC          C compiler command
1526  CFLAGS      C compiler flags
1527  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1528              nonstandard directory <lib dir>
1529  LIBS        libraries to pass to the linker, e.g. -l<library>
1530  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1531              you have headers in a nonstandard directory <include dir>
1532  CPP         C preprocessor
1533
1534Use these variables to override the choices made by `configure' or to help
1535it to find libraries and programs with nonstandard names/locations.
