791 Usage: $0 [OPTION]... [VAR=VALUE]...
792
793 To assign environment variables (e.g., CC, CFLAGS...), specify them as
794 VAR=VALUE. See below for descriptions of some of the useful variables.
795
796 Defaults for the options are specified in brackets.
797
798 Configuration:
799 -h, --help display this help and exit
800 --help=short display options specific to this package
801 --help=recursive display the short help of all the included packages
802 -V, --version display version information and exit
803 -q, --quiet, --silent do not print \`checking...' messages
804 --cache-file=FILE cache test results in FILE [disabled]
805 -C, --config-cache alias for \`--cache-file=config.cache'
806 -n, --no-create do not create output files
807 --srcdir=DIR find the sources in DIR [configure dir or \`..']

901 Some influential environment variables:
902 CC C compiler command
903 CFLAGS C compiler flags
904 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
905 nonstandard directory <lib dir>
906 CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have
907 headers in a nonstandard directory <include dir>
908 CPP C preprocessor
909 CXX C++ compiler command
910 CXXFLAGS C++ compiler flags
911
912 Use these variables to override the choices made by `configure' or to help
913 it to find libraries and programs with nonstandard names/locations.
