783
784 To assign environment variables (e.g., CC, CFLAGS...), specify them as
785 VAR=VALUE. See below for descriptions of some of the useful variables.
786
787 Defaults for the options are specified in brackets.
788
789 Configuration:
790 -h, --help display this help and exit
791 --help=short display options specific to this package
792 --help=recursive display the short help of all the included packages
793 -V, --version display version information and exit
794 -q, --quiet, --silent do not print \`checking...' messages
795 --cache-file=FILE cache test results in FILE [disabled]
796 -C, --config-cache alias for \`--cache-file=config.cache'
797 -n, --no-create do not create output files

864 Use to measure compiler performance and locate
865 unused parts of the compiler. With LEVEL, specify
866 optimization. Values are opt, noopt,
867 default is noopt
868 --enable-gather-detailed-mem-stats enable detailed memory allocation stats gathering

890 (and sometimes confusing) to the casual installer
891 --enable-version-specific-runtime-libs
892 specify that runtime libraries should be
893 installed in a compiler-specific directory
894
895 Optional Packages:
896 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
897 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
898 --with-local-prefix=DIR specifies directory to put local include
899 --with-gxx-include-dir=DIR
900 specifies directory to put g++ header files
901 --with-cpp-install-dir=DIR
902 install the user visible C preprocessor in DIR

909 --with-dwarf2 force the default debug format to be DWARF 2
910 --with-sysroot=DIR Search for usr/lib, usr/include, et al, within DIR.
911 --with-libiconv-prefix=DIR search for libiconv in DIR/include and DIR/lib
912 --with-gc={page,zone} choose the garbage collection mechanism to use
913 with the compiler
914 --with-system-zlib use installed libz
915 --with-slibdir=DIR shared libraries in DIR LIBDIR
916
917 Some influential environment variables:
918 CC C compiler command
919 CFLAGS C compiler flags
920 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
921 nonstandard directory <lib dir>
922 CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have
923 headers in a nonstandard directory <include dir>
924 CPP C preprocessor
925
926 Use these variables to override the choices made by `configure' or to help
927 it to find libraries and programs with nonstandard names/locations.
