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'

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

906 --with-gnu-as arrange to work with GNU as
907 --with-as arrange to use the specified as (full pathname)
908 --with-stabs arrange to use stabs instead of host debug format
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.
