DESCRIPTION
The
lipo
command creates or operates on ``fat'' (multi-architecture) files.
It only ever produces one output file,
and never alters the input file. The operations that
lipo
performs are:
listing the architecture types in a fat file;
creating a single fat file from one or more input files;
thinning out a single fat file to one specified architecture type;
and extracting, replacing, and/or removing architectures
types from the input file to create a single new fat output file.
Only one option can be specified,
with the exception of
-arch,
-output,
and
-segalign,
which are used in combination with other options.
The
input_file
argument is required, and only the
-create
option allows more than one
input_file
to be specified.
The
-output
flag must be used, except with the
-info
and
-detailed_info
flags.
The
arch_type
arguments may be any of the supported architecture names listed in the man page
arch.3
OPTIONS
- -info
-
Briefly list the architecture types in the input fat file
(just the names of each architecture).
- -detailed_info
-
Display a detailed list of the architecture types in the input fat file
(all the the information in the fat header, for each architecture in the file).
- -arch arch_type input_file
-
Tells
lipo
that
input_file
contains the specified architecture type.
The
-arch arch_type
specification is unnecessary if
input_file
is an
object file, a fat file, or some other file whose architecture(s)
lipo
can figure out.
- -output output_file
-
Specifies its argument to be the output file.
- -create
-
Take the input files (or file) and create one fat output file from them.
- -thin arch_type
-
Take one input file and create a thin output file with the specified
arch_type.
- -replace arch_type file_name
-
Take one fat input file; in the output file, replace the
arch_type
contents of the input file with the contents of the specified
file_name.
- -remove arch_type
-
Take one fat input file and remove the
arch_type
from that fat file, placing the result in the output file.
- -extract arch_type
-
Take one fat input file and copy the
arch_type
from that fat file into a fat output file containing
only that architecture.
- -extract_family arch_type
-
Take one fat input file and copy all of the
arch_types
for the family that
arch_type
is in from that fat file into an output file containing
only those architectures. The file will be thin if only one architecture is
found or fat otherwise.
- -segalign arch_type value
-
Set the segment alignment of the specified
arch_type
when creating a fat file containing that architecture.
value
is a hexadecimal number that must be an integral power of 2.
This is only needed when
lipo
can't figure out the alignment of an input file
(currently not an object file),
or when it guesses at the alignment too conservatively.
The default for files unknown to
lipo
is 0 (2^0, or an alignment of one byte),
and the default alignment for archives
is 4 (2^2, or 4-byte alignment).
