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

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

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