Usage: ./configure [OPTION]... [VAR=VALUE]... To assign environment variables (e.g., CC, CFLAGS...), specify them as VAR=VALUE. See below for descriptions of some of the useful variables. Defaults for the options are specified in brackets. Configuration: -h, --help display this help and exit --help=short display options specific to this package --help=recursive display the short help of all the included packages -V, --version display version information and exit -q, --quiet, --silent do not print `checking ...' messages --cache-file=FILE cache test results in FILE [disabled] -C, --config-cache alias for `--cache-file=config.cache' -n, --no-create do not create output files --srcdir=DIR find the sources in DIR [configure dir or `..'] Installation directories: --prefix=PREFIX install architecture-independent files in PREFIX [/usr/local] --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX [PREFIX] By default, `make install' will install all the files in `/usr/local/bin', `/usr/local/lib' etc. You can specify an installation prefix other than `/usr/local' using `--prefix', for instance `--prefix=$HOME'. For better control, use the options below. Fine tuning of the installation directories: --bindir=DIR user executables [EPREFIX/bin] --sbindir=DIR system admin executables [EPREFIX/sbin] --libexecdir=DIR program executables [EPREFIX/libexec] --sysconfdir=DIR read-only single-machine data [PREFIX/etc] --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com] --localstatedir=DIR modifiable single-machine data [PREFIX/var] --libdir=DIR object code libraries [EPREFIX/lib] --includedir=DIR C header files [PREFIX/include] --oldincludedir=DIR C header files for non-gcc [/usr/include] --datarootdir=DIR read-only arch.-independent data root [PREFIX/share] --datadir=DIR read-only architecture-independent data [DATAROOTDIR] --infodir=DIR info documentation [DATAROOTDIR/info] --localedir=DIR locale-dependent data [DATAROOTDIR/locale] --mandir=DIR man documentation [DATAROOTDIR/man] --docdir=DIR documentation root [DATAROOTDIR/doc/PACKAGE] --htmldir=DIR html documentation [DOCDIR] --dvidir=DIR dvi documentation [DOCDIR] --pdfdir=DIR pdf documentation [DOCDIR] --psdir=DIR ps documentation [DOCDIR] System types: --build=BUILD configure for building on BUILD [guessed] --host=HOST cross-compile to build programs to run on HOST [BUILD] --target=TARGET configure for building compilers for TARGET [HOST] Optional Features: --disable-option-checking ignore unrecognized --enable/--with options --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no) --enable-FEATURE[=ARG] include FEATURE [ARG=yes] --enable-layout=LAYOUT --enable-experimental-libtool Use experimental custom libtool --enable-shared[=PKGS] build shared libraries [default=yes] --enable-static[=PKGS] build static libraries [default=yes] --enable-fast-install[=PKGS] optimize for fast installation [default=yes] --disable-libtool-lock avoid locking (might break parallel builds) --enable-debug Turn on debugging and compile time warnings --enable-maintainer-mode Turn on debugging and compile time warnings --enable-profile Turn on profiling for the build (GCC) --enable-pool-debug[=yes|no|verbose|verbose-alloc|lifetime|owner|all] Turn on pools debugging --enable-malloc-debug Switch on malloc_debug for BeOS --disable-lfs Disable large file support on 32-bit platforms --enable-nonportable-atomics Use optimized atomic code which may produce nonportable binaries --enable-threads Enable threading support in APR. --enable-allocator-uses-mmap Use mmap in apr_allocator instead of malloc (experimental) --disable-dso Disable DSO support --enable-other-child Enable reliable child processes --disable-ipv6 Disable IPv6 support in APR. Optional Packages: --with-PACKAGE[=ARG] use PACKAGE [ARG=yes] --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no) --with-gnu-ld assume the C compiler uses GNU ld [default=no] --with-pic try to use only PIC/non-PIC objects [default=use both] --with-tags[=TAGS] include additional configurations [automatic] --with-installbuilddir=DIR location to store APR build files (defaults to '${datadir}/build') --without-libtool avoid using libtool to link the library --with-efence[=DIR] path to Electric Fence installation --with-sendfile Override decision to use sendfile --with-egd[=DIR] use EGD-compatible socket --with-devrandom[=DEV] use /dev/random or compatible [searches by default] Some influential environment variables: CC C compiler command CFLAGS C compiler flags LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a nonstandard directory <lib dir> LIBS libraries to pass to the linker, e.g. -l<library> CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if you have headers in a nonstandard directory <include dir> CPP C preprocessor CXX C++ compiler command CXXFLAGS C++ compiler flags CXXCPP C++ preprocessor F77 Fortran 77 compiler command FFLAGS Fortran 77 compiler flags Use these variables to override the choices made by `configure' or to help it to find libraries and programs with nonstandard names/locations.
