19e173a1ecSIngo Weinhold                              Prepare for a bootstrap build. No pre-built
20e173a1ecSIngo Weinhold                              packages will be used, instead they will be built
21e173a1ecSIngo Weinhold                              from the sources (in several phases).
22e173a1ecSIngo Weinhold                              <haikuporter> is the path to the haikuporter tool
23e173a1ecSIngo Weinhold                              suitable for the host platform.
24e173a1ecSIngo Weinhold                              <HaikuPorts cross repo> is the path to a checked

26e173a1ecSIngo Weinhold                              <HaikuPorts repo> is the path to a checked out

28c0e8cc1aSIngo Weinhold  --build-cross-tools <arch> [ <build tools dir> ]
29338b8dc3SIngo Weinhold                              Assume cross compilation. <build tools dir>
30338b8dc3SIngo Weinhold                              defines the location of the build tools sources.
31338b8dc3SIngo Weinhold                              They will be compiled and placed in the output
32a5b60fa8SOliver Tappe                              directory under "cross-tools". The HAIKU_* tools
33a5b60fa8SOliver Tappe                              variables will be set accordingly.
3420ab75e6SIngo Weinhold                              <arch> specifies the target architecture, either
35fb4cc984SAugustin Cavalier                              "x86_gcc2", "x86", "x86_64", "ppc", "m68k", "arm", "arm64"
36c0e8cc1aSIngo Weinhold                              This option and --cross-tools-prefix can be
37c0e8cc1aSIngo Weinhold                              specified multiple times. The first cross tools
38c0e8cc1aSIngo Weinhold                              specify the primary tools, the subsequent ones the
39c0e8cc1aSIngo Weinhold                              secondary tools (for "hybrid" images).
40c0e8cc1aSIngo Weinhold                              For the first --build-cross-tools the
41c0e8cc1aSIngo Weinhold                              <build tools dir> argument must be specified and
42c0e8cc1aSIngo Weinhold                              for the subsequent ones it must be omitted.
43eccc7665SIngo Weinhold  --cross-tools-prefix <prefix>
44eccc7665SIngo Weinhold                              Assume cross compilation. <prefix> should be a
45eccc7665SIngo Weinhold                              path to the directory where the cross
46eccc7665SIngo Weinhold                              compilation tools are located, plus the platform
470da9c208SIngo Weinhold                              prefix, e.g. "/path/to/tools/i586-pc-haiku-".
48eccc7665SIngo Weinhold                              This overrides the HAIKU_* tool variables.
49a66c32ddSIngo Weinhold  --distro-compatibility <level>
50a66c32ddSIngo Weinhold                              The distribution's level of compatibility with
51a66c32ddSIngo Weinhold                              the official Haiku distribution. The generated
52a66c32ddSIngo Weinhold                              files will contain the respective trademarks
53a66c32ddSIngo Weinhold                              accordingly.
54a66c32ddSIngo Weinhold                              official -- the official Haiku distribution.
55a66c32ddSIngo Weinhold                              compatible -- a Haiku Compatible (tm) distro.
56a66c32ddSIngo Weinhold                              default -- any other distro (default value).
572ebcd86dSIngo Weinhold  --host-only                 Configure for building tools for the build host
582ebcd86dSIngo Weinhold                              only. Haiku cannot be built when configured like
592ebcd86dSIngo Weinhold                              this.
6076fa0be3SIngo Weinhold  --include-sources           Includes the source code of projects that require
6176fa0be3SIngo Weinhold                              either an offer of source code or a copy of the
6276fa0be3SIngo Weinhold                              patched sources. This is preferable when
6376fa0be3SIngo Weinhold                              distributing on physical mediums.
641974210fSFrançois Revol  --include-3rdparty          Include 3rdparty/ in the build system.
654880ae01SJessica Hamilton  -j<n>                       Only relevant for --build-cross-tools. Is passed
664880ae01SJessica Hamilton                              on to the make building the build tools.
67aa2e5ecaSOliver Tappe  --no-downloads              Do not download anything. Useful when trying to
68aa2e5ecaSOliver Tappe                              bootstrap and build Haiku from source only.
69483b28e4SIngo Weinhold  --target-arch <arch>        Haiku only: Specify the target architecture to
70483b28e4SIngo Weinhold                              build for. Must be one of the architectures of the
71483b28e4SIngo Weinhold                              host system. The installed build tools for that
72483b28e4SIngo Weinhold                              architecture will be used.
73483b28e4SIngo Weinhold                              This option can be specified multiple times. The
74483b28e4SIngo Weinhold                              first occurrence specifies the primary
75483b28e4SIngo Weinhold                              architecture of the Haiku to build, subsequent
76483b28e4SIngo Weinhold                              ones the secondary architectures.
77d73993ffSAugustin Cavalier  --use-clang <arch>          Build with host Clang instead of GCC cross
78d73993ffSAugustin Cavalier                              compiler, targeting <arch>
79eccc7665SIngo Weinhold  --use-gcc-pipe              Build with GCC option -pipe. Speeds up the build
805a34a443SFrançois Revol                              process, but uses more memory.
81ed38d2efSJerome Duval  --use-gcc-graphite          Build with GCC Graphite engine for loop
82a5c952dbSAugustin Cavalier                              optimizations. (Only for GCC 4+.)
830385b065SIngo Weinhold  --use-32bit                 Use -m32 flag on 64bit host gcc compiler.
84fc2c93fbSAugustin Cavalier  --no-full-xattr             Do not use Linux/*BSD/Darwin's native extended file

86fc2c93fbSAugustin Cavalier                              available, they will be used to store hashes for
87fc2c93fbSAugustin Cavalier                              the attribute emulation layer.
88fc2c93fbSAugustin Cavalier  --no-xattr                  Do not use Linux/*BSD/Darwin's native extended file
89fc2c93fbSAugustin Cavalier                              attributes for Haiku extended attributes at all,
90fc2c93fbSAugustin Cavalier                              even if they are available.
914da6cf84SFrançois Revol  --with-gdb <gdb sources dir>
924da6cf84SFrançois Revol                              specify the path to a GDB source dir, to build
934da6cf84SFrançois Revol                              GDB for each arch we build the cross-tools for.

12664f6da31SIngo Weinhold  stored in /path/to/haiku_source/generated.  To store objects in a non-default
1275abd9a46SIngo Weinhold  location, run "../../relative/path/to/haiku_source/configure <options>" from
1285abd9a46SIngo Weinhold  within your non-default location.  "jam [ options ] targets" can then be run
1295abd9a46SIngo Weinhold  directly inside your non-default location.  Another option is to invoke "jam
1305abd9a46SIngo Weinhold  [ options ] targets" from within haiku_source.  This can be accomplished by
1315abd9a46SIngo Weinhold  either "export HAIKU_OUTPUT_DIR=your non-default location" before invoking
1325abd9a46SIngo Weinhold  jam or by creating a symlink of haiku_source/generated pointing to your
13364f6da31SIngo Weinhold  non-default location and running jam.
