metal-lipo - Metal tool for manipulating universal binaries
metal-lipo [filenames...] [options]
metal-lipo can create universal binaries from Mach-O files,
extract regular object files from universal binaries, and display
architecture information about both universal and regular files.
metal-lipo supports the following mutually exclusive
commands:
- -help, -h
- Display usage information and exit.
- -version
- Display the version of this program.
- -archs
- Take a single input file and display the architectures present in the
file. Each architecture is separated by a single whitespace. Unknown
architectures are displayed as unknown(CPUtype,CPUsubtype).
- -info
- Take at least one input file and display the descriptions of each file.
The descriptions include the filename and architecture types separated by
whitespace. Universal binaries are grouped together first, followed by
thin files. Architectures in the fat file: <filename> are:
<architectures> Non-fat file: <filename> is architecture:
<architecture>
- -thin
- Take a single universal binary input file and the thin flag followed by an
architecture type. Require the output flag to be specified, and output a
thin binary of the specified architecture.
- -create
- Take at least one input file and require the output flag to be specified.
Output a universal binary combining the input files.
- -replace
- Take a single universal binary input file and require the output flag to
be specified. The replace flag is followed by an architecture type, and a
thin input file. Output a universal binary with the specified architecture
slice in the universal binary input replaced with the contents of the thin
input file.
- -segalign
- Additional flag that can be specified with create and replace. The
segalign flag is followed by an architecture type, and an alignment. The
alignment is a hexadecimal number that is a power of 2. Output a file in
which the slice with the specified architecture has the specified
alignment.
