Usage: $0 <options>
options:
  --build-cross-tools <build tools dir>
                              Assume cross compilation. <build tools dir>
                              defines the location of the build tools sources.
                              They will be compiled and placed in the output
                              directory under "cross-tools". The HAIKU_* tools
                              variables will be set accordingly.
  --build-cross-tools-gcc4 <arch> <build tools dir>
                              Like "--build-cross-tools" just that gcc 4 will
                              be used for cross-compilation. Note, that the
                              resulting Haiku installation built with gcc 4
                              will not be binary compatible with BeOS R5.
                              <arch> specifies the target architecture, either
                              "x86", "x86_64", "ppc", "m68k", "arm" or "mipsel".
  --cross-tools-prefix <prefix>
                              Assume cross compilation. <prefix> should be a
                              path to the directory where the cross
                              compilation tools are located, plus the platform
                              prefix, e.g. "/path/to/tools/i586-pc-haiku-".
                              This overrides the HAIKU_* tool variables.
  --distro-compatibility <level>
                              The distribution's level of compatibility with
                              the official Haiku distribution. The generated
                              files will contain the respective trademarks
                              accordingly.
                              official -- the official Haiku distribution.
                              compatible -- a Haiku Compatible (tm) distro.
                              default -- any other distro (default value).
  --enable-multiuser          Enable experimental multiuser support.
  --help                      Prints out this help.
  --host-only                 Configure for building tools for the build host
                              only. Haiku cannot be built when configured like
                              this.
  --include-gpl-addons        Include GPL licensed add-ons.
  --include-patented-code     Enable code that is known to implemented patented
                              ideas and techniques. If this option is not
                              specified, the resulting distribution may still
                              implement patented ideas and techniques. This
                              option only disables code that is currently known
                              to be problematic.
  --include-sources           Includes the source code of projects that require
                              either an offer of source code or a copy of the
                              patched sources. This is preferable when
                              distributing on physical mediums.
  --include-3rdparty          Include 3rdparty/ in the build system.
  -j<n>                       Only relevant for --build-cross-tools and
                              --build-cross-tools-gcc4. Is passed on to the
                              make building the build tools.
  --target=TARGET             Select build target platform.
                              [default=${TARGET_PLATFORM}]
                              valid targets=r5,bone,dano,haiku
  --update                    re-runs last configure invocation [must be given
                              as first option!]
  --use-gcc-pipe              Build with GCC option -pipe. Speeds up the build
                              process, but uses more memory.
  --use-gcc-graphite          Build with GCC Graphite engine for loop
                              optimizations. Only for gcc 4.
  --use-32bit                 Use -m32 flag on 64bit host gcc compiler.
  --use-xattr                 Use Linux xattr respectively *BSD extattr support
                              for BeOS attribute emulation. Warning: Make sure
                              your file system supports sufficient attribute
                              sizes (4 KB per file for all attributes won't
                              suffice).
  --use-xattr-ref             Use the generic BeOS attribute emulation, but use
                              Linux xattr respectively *BSD extattr support to
                              make it more robust (i.e. attribute mix-ups become
                              less likely).

environment variables:
  HAIKU_AR                    The static library archiver. Defaults to "ar".
  HAIKU_CC                    The compiler. Defaults to "gcc".
  HAIKU_LD                    The linker. Defaults to "ld".
  HAIKU_OBJCOPY               The objcopy to be used. Defaults to "objcopy".
  HAIKU_RANLIB                The static library indexer. Defaults to "ranlib".
  HAIKU_YASM                  The yasm assembler (x86 only).
  HAIKU_STRIP                 The strip command. Defaults to "strip".
  HAIKU_CPPFLAGS              The preprocessor flags. Defaults to "".
  HAIKU_CCFLAGS               The C flags. Defaults to "".
  HAIKU_CXXFLAGS              The C++ flags. Defaults to "".
  HAIKU_LDFLAGS               The linker flags. Defaults to "".
  HAIKU_ARFLAGS               The flags passed to HAIKU_AR for archiving.
                              Defaults to "cru".
  HAIKU_UNARFLAGS             The flags passed to HAIKU_AR for unarchiving.
                              Defaults to "x".

Non-standard output directories:
  By default all objects, build configuration, and other related files are
  stored in /path/to/haiku_source/generated.  To store objects in a non-default
  location, run "../../relative/path/to/haiku_source/configure <options>" from
  within your non-default location.  "jam [ options ] targets" can then be run
  directly inside your non-default location.  Another option is to invoke "jam
  [ options ] targets" from within haiku_source.  This can be accomplished by
  either "export HAIKU_OUTPUT_DIR=your non-default location" before invoking
  jam or by creating a symlink of haiku_source/generated pointing to your
  non-default location and running jam.
