lipo

LIPO(1) 						      General Commands Manual							   LIPO(1)

NAME

       lipo - create or operate on fat files

SYNOPSIS

       lipo  [-info]  [-detailed_info]	[-arch arch_type input_file] ...  [ input_file] ...  [-create] [-thin arch_type] [-replace arch_type file-
       name] ...  [-remove arch_type] ...  [-extract arch_type] ...  [-extract_family arch_type] ...  [-output output_file]  [-segalign  arch_type
       value] ...

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 architec-
       tures 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)exceptforVAXandMips.

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  archi-
	      tecture 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 (cur-
	      rently 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).
