compatibility relation to the official Haiku distribution. "official"
is for the official Haiku distribution itself, "compatible" for Haiku
Compatible (tm) distros, and "default" for all others (the default value
for the option). The build system variable HAIKU_DISTRO_COMPATIBILITY is
defined accordingly, and one of the
HAIKU_DISTRO_COMPATIBILITY_{OFFICIAL,COMPATIBLE,DEFAULT} macros is
defined for source code and rdefs.

Usage: $0 <options>
|
|
options:
|
|
--bochs-debug Enables bochs serial debug emulation (activated
|
|
via kernel settings file).
|
|
--build-cross-tools <build tools dir>
|
|
Assume cross compilation. <build tools dir>
|
|
defines the location of the build tools sources.
|
|
They will be compiled and placed in the output
|
|
directory under "cross-tools". The HAIKU_* tools
|
|
variables will be set accordingly.
|
|
--build-cross-tools-gcc4 <arch> <build tools dir>
|
|
Like "--build-cross-tools" just that gcc 4 will
|
|
be used for cross-compilation. Note, that the
|
|
resulting Haiku installation built with gcc 4
|
|
will not be binary compatible with BeOS R5.
|
|
<arch> specifies the target architecture, either
|
|
"x86" or "ppc".
|
|
--cross-tools-prefix <prefix>
|
|
Assume cross compilation. <prefix> should be a
|
|
path to the directory where the cross
|
|
compilation tools are located, plus the platform
|
|
prefix, e.g. "/path/to/tools/i586-pc-beos-".
|
|
This overrides the HAIKU_* tool variables.
|
|
--distro-compatibility <level>
|
|
The distribution's level of compatibility with
|
|
the official Haiku distribution. The generated
|
|
files will contain the respective trademarks
|
|
accordingly.
|
|
official -- the official Haiku distribution.
|
|
compatible -- a Haiku Compatible (tm) distro.
|
|
default -- any other distro (default value).
|
|
--help Prints out this help.
|
|
--include-gpl-addons Include GPL licensed add-ons.
|
|
--target=TARGET Select build target platform. [default=${target}]
|
|
valid targets=r5,bone,dano,haiku
|
|
--use-gcc-pipe Build with GCC option -pipe. Speeds up the build
|
|
process, but uses more memory.
|
|
--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_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 "ru".
|
|
HAIKU_UNARFLAGS The flags passed to HAIKU_AR for unarchiving.
|
|
Defaults to "x".
