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