Usage: $0 <options>
options:
--floppy <floppy location> Specifies the location of the floppy
(device or image).
--bochs-debug Enables bochs serial debug emulation (activated
via kernel settings file).
--cross-tools-prefix <prefix>
Assume cross compilation. <prefix> should be a
path to the directory where the cross
compilation tools are located, plus the platform
prefix, e.g. "/path/to/tools/i586-pc-beos-".
This overrides the HAIKU_* tool variables.
--build-cross-tools <build tools dir>
Assume cross compilation. <build tools dir>
defines the location of the build tools sources.
They will be compiled and placed in the output
directory under "cross-tools-legacy". The HAIKU_*
tools variables will be set accordingly.
--build-cross-tools-gcc4 <arch> <build tools dir>
Like "--build-cross-tools" just that gcc 4 will
be used for cross-compilation and the cross-tools
will be placed in the output directory under
"cross-tools-current". Note, that the resulting
Haiku installation built with gcc 4 will not be
binary compatible with BeOS R5.
<arch> specifies the target architecture, either
"x86" or "ppc".
--use-cross-tools
Selects the cross-tools from "cross-tools-legacy"
for compilation. The HAIKU_* tools variables will
be set accordingly.
--use-cross-tools-gcc4 <arch>
Selects the cross-tools from "cross-tools-gcc4"
for compilation. The HAIKU_* tools variables will
be set accordingly.
<arch> specifies the target architecture, either
"x86" or "ppc".
--target=TARGET Select build target platform. [default=${target}]
valid targets=r5,bone,dano,haiku
--include-gpl-addons Include GPL licensed add-ons.
--help Prints out this help.
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".
