Usage: $0 <options>
options:
--alternative-gcc-output-dir <dir>
Build a Haiku installation that supports running
executables built with a gcc version incompatible
with the primary gcc (e.g. gcc 2 executables under
a gcc 4 Haiku or vice versa). <dir> specifies the
output directory of the other gcc. The directory
must already be fully configured.
Note, that a sub-jam will be executed when
building Haiku. When using a jam that is not
simply invoked by "jam", the JAM build variable
needs to be set accordingly.
To disable building the alternative libraries
the variable HAIKU_ADD_ALTERNATIVE_GCC_LIBS can be
unset in the UserBuildConfig file.
--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.
--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-32bit Use -m32 flag on 64bit host gcc compiler.
--use-xattr Use Linux xattr 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).
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_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.
