1408   -n, --no-create         do not create output files

1411 Installation directories:
1412   --prefix=PREFIX         install architecture-independent files in PREFIX
1413                           [$ac_default_prefix]
1414   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1415                           [PREFIX]
1416
1417 By default, \`make install' will install all the files in
1418 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1419 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1420 for instance \`--prefix=\$HOME'.

1473 Some influential environment variables:
1474   CC          C compiler command
1475   CFLAGS      C compiler flags
1476   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1477               nonstandard directory <lib dir>
1478   LIBS        libraries to pass to the linker, e.g. -l<library>
1479   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1480               you have headers in a nonstandard directory <include dir>
1481   CPP         C preprocessor
1482
1483 Use these variables to override the choices made by `configure' or to help
1484 it to find libraries and programs with nonstandard names/locations.
