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

822 By default, \`make install' will install all the files in

907 Some influential environment variables:
908 CC C compiler command
909 CFLAGS C compiler flags
910 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
911 nonstandard directory <lib dir>
912 CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have
913 headers in a nonstandard directory <include dir>
914 CPP C preprocessor
915 CXX C++ compiler command
916 CXXFLAGS C++ compiler flags
917
918 Use these variables to override the choices made by `configure' or to help
919 it to find libraries and programs with nonstandard names/locations.
