14options:
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: Specify the board to build for. Must be
87                              one of beagle,rpi1,rpi2,cubieboard4,verdex,overo.
88  --update                    re-runs last configure invocation [must be given
89                              as first option!]
90  --use-clang                 Build with host Clang instead of GCC cross
91                              compiler
92  --use-gcc-pipe              Build with GCC option -pipe. Speeds up the build
93                              process, but uses more memory.
94  --use-gcc-graphite          Build with GCC Graphite engine for loop
95                              optimizations. Only for gcc 4.
96  --use-32bit                 Use -m32 flag on 64bit host gcc compiler.
97  --use-xattr                 Use Linux xattr respectively *BSD extattr support
98                              for BeOS attribute emulation. Warning: Make sure
99                              your file system supports sufficient attribute
100                              sizes (4 KB per file for all attributes won't
101                              suffice).
102  --use-xattr-ref             Use the generic BeOS attribute emulation, but use
103                              Linux xattr respectively *BSD extattr support to
104                              make it more robust (i.e. attribute mix-ups become
105                              less likely).
106

115  HAIKU_RANLIB_x86_gcc2       The static library indexer for x86_gcc2. Defaults
116                              to "ranlib".
117  HAIKU_STRIP_x86_gcc2        The x86_gcc2 strip command. Defaults to "strip".
118  HAIKU_NASM                  The nasm assembler (x86 and x86_64 only).

122                              Defaults to "".
123  HAIKU_CXXFLAGS_<arch>       The C++ flags for target architecture <arch>.
124                              Defaults to "".
125  HAIKU_LDFLAGS_<arch>        The linker flags for target architecture <arch>.
126                              Defaults to "".
127  HAIKU_ARFLAGS_<arch>        The flags passed to HAIKU_AR for target

133
134Non-default output directories:
135  By default all objects, build configuration, and other related files are
136  stored in /path/to/haiku_source/generated.  To store objects in a non-default
137  location, run "../../relative/path/to/haiku_source/configure <options>" from
138  within your non-default location.  "jam [ options ] targets" can then be run
139  directly inside your non-default location.  Another option is to invoke "jam
140  [ options ] targets" from within haiku_source.  This can be accomplished by
141  either "export HAIKU_OUTPUT_DIR=your non-default location" before invoking
142  jam or by creating a symlink of haiku_source/generated pointing to your
143  non-default location and running jam.
