  15   --bootstrap <haikuporter> <HaikuPorts cross repo> <HaikuPorts repo>
  16                               Prepare for a bootstrap build. No pre-built
  17                               packages will be used, instead they will be built
  18                               from the sources (in several phases).
  19                               <haikuporter> is the path to the haikuporter tool
  20                               suitable for the host platform.
  21                               <HaikuPorts cross repo> is the path to a checked
  22                               out HaikuPorts cross-compilation repository.
  23                               <HaikuPorts repo> is the path to a checked out
  24                               HaikuPorts repository.
  25   --build-cross-tools <arch> [ <build tools dir> ]
  26                               Assume cross compilation. <build tools dir>
  27                               defines the location of the build tools sources.
  28                               They will be compiled and placed in the output
  29                               directory under "cross-tools". The HAIKU_* tools
  30                               variables will be set accordingly.
  31                               <arch> specifies the target architecture, either
  32                               "x86_gcc2", "x86", "x86_64", "ppc", "m68k", "arm"
  33                               This option and --cross-tools-prefix can be
  34                               specified multiple times. The first cross tools
  35                               specify the primary tools, the subsequent ones the
  36                               secondary tools (for "hybrid" images).
  37                               For the first --build-cross-tools the
  38                               <build tools dir> argument must be specified and
  39                               for the subsequent ones it must be omitted.
  40   --cross-tools-prefix <prefix>
  41                               Assume cross compilation. <prefix> should be a
  42                               path to the directory where the cross
  43                               compilation tools are located, plus the platform
  44                               prefix, e.g. "/path/to/tools/i586-pc-haiku-".
  45                               This overrides the HAIKU_* tool variables.
  46   --distro-compatibility <level>
  47                               The distribution's level of compatibility with
  48                               the official Haiku distribution. The generated
  49                               files will contain the respective trademarks
  50                               accordingly.
  51                               official -- the official Haiku distribution.
  52                               compatible -- a Haiku Compatible (tm) distro.
  53                               default -- any other distro (default value).
  54   --enable-multiuser          Enable experimental multiuser support.
  55   --help                      Prints out this help.
  56   --host-only                 Configure for building tools for the build host
  57                               only. Haiku cannot be built when configured like
  58                               this.
  59   --include-gpl-addons        Include GPL licensed add-ons.
  60   --include-patented-code     Enable code that is known to implemented patented
  61                               ideas and techniques. If this option is not
  62                               specified, the resulting distribution may still
  63                               implement patented ideas and techniques. This
  64                               option only disables code that is currently known
  65                               to be problematic.
  66   --include-sources           Includes the source code of projects that require
  67                               either an offer of source code or a copy of the
  68                               patched sources. This is preferable when
  69                               distributing on physical mediums.
  70   --include-3rdparty          Include 3rdparty/ in the build system.
  71   -j<n>                       Only relevant for --build-cross-tools. Is passed
  72                               on to the make building the build tools.
  73   --no-downloads              Do not download anything. Useful when trying to
  74                               bootstrap and build Haiku from source only.
  75   --target=TARGET             Select build target platform.
  76                               [default=${TARGET_PLATFORM}]
  77                               valid targets=r5,bone,dano,haiku,host
  78   --target-arch <arch>        Haiku only: Specify the target architecture to
  79                               build for. Must be one of the architectures of the
  80                               host system. The installed build tools for that
  81                               architecture will be used.
  82                               This option can be specified multiple times. The
  83                               first occurrence specifies the primary
  84                               architecture of the Haiku to build, subsequent
  85                               ones the secondary architectures.
  86   --target-board <board>      ARM only: Target board to build for.
  87                               <board> is one of: "beagleboard","beaglebone",
  88                               "rpi1","rpi2","cubieboard4","verdex","overo"
  89   --update                    re-runs last configure invocation [must be given
  90                               as first option!]
  91   --use-clang                 Build with host Clang instead of GCC cross
  92                               compiler
  93   --use-gcc-pipe              Build with GCC option -pipe. Speeds up the build
  94                               process, but uses more memory.
  95   --use-gcc-graphite          Build with GCC Graphite engine for loop
  96                               optimizations. Only for gcc 4.
  97   --use-32bit                 Use -m32 flag on 64bit host gcc compiler.
  98   --use-xattr                 Use Linux xattr respectively *BSD extattr support
  99                               for BeOS attribute emulation. Warning: Make sure
 100                               your file system supports sufficient attribute
 101                               sizes (4 KB per file for all attributes won't
 102                               suffice).
 103   --use-xattr-ref             Use the generic BeOS attribute emulation, but use
 104                               Linux xattr respectively *BSD extattr support to
 105                               make it more robust (i.e. attribute mix-ups become
 106                               less likely).
 107   --with-gdb <gdb sources dir>
 108                               specify the path to a GDB source dir, to build
 109                               GDB for each arch we build the cross-tools for.

 128                               Defaults to "".
 129   HAIKU_LDFLAGS_<arch>        The linker flags for target architecture <arch>.

 137
 138 Non-default output directories:
 139   By default all objects, build configuration, and other related files are
 140   stored in /path/to/haiku_source/generated.  To store objects in a non-default
 141   location, run "../../relative/path/to/haiku_source/configure <options>" from
 142   within your non-default location.  "jam [ options ] targets" can then be run
 143   directly inside your non-default location.  Another option is to invoke "jam
 144   [ options ] targets" from within haiku_source.  This can be accomplished by
 145   either "export HAIKU_OUTPUT_DIR=your non-default location" before invoking
 146   jam or by creating a symlink of haiku_source/generated pointing to your
 147   non-default location and running jam.
