SETARCH(8) System Administration SETARCH(8)NAME
setarch - change reported architecture in new program environment and set personality flags
SYNOPSIS
setarch arch [options] [program [arguments]]
arch [options] [program [arguments]]
DESCRIPTION
setarch This utility currently only affects the output of uname -m. For example, on an AMD64 system, running 'setarch i386 program' will
cause 'program' to see i686 (or other relevant arch) instead of x86_64 as machine type. It also allows to set various personality options.
The default program is /bin/sh.
OPTIONS -v, --verbose
Be verbose.
-h, --help
Display help (it is also displayed when setarch takes no arguments).
--uname-2.6
Causes the program to see a kernel version number beginning with 2.6.
-3, --3gb
Specifies that processes should use a maximum of 3GB of address space on systems where it is supported (ADDR_LIMIT_3GB).
-B, --32bit
Turns on ADDR_LIMIT_32BIT.
-F, --fdpic-funcptrs
Userspace function pointers point to descriptors (turns on FDPIC_FUNCPTRS).
-I, --short-inode
Turns on SHORT_INODE.
-L, --addr-compat-layout
Changes the way virtual memory is allocated (turns on the ADDR_COMPAT_LAYOUT).
-R, --addr-no-randomize
Disables randomization of the virtual address space (turns on ADDR_NO_RANDOMIZE).
-S, --whole-seconds
Turns on WHOLE_SECONDS.
-T, --sticky-timeouts
Turns on STICKY_TIMEOUTS.
-X --read-implies-exec
Turns on READ_IMPLIES_EXEC.
-Z, mmap-page-zero
Turns on MMAP_PAGE_ZERO.
EXAMPLES
setarch ppc32 rpmbuild --target=ppc --rebuild foo.src.rpm
setarch ppc32 -v -vL3 rpmbuild --target=ppc --rebuild bar.src.rpm
setarch ppc32 --32bit rpmbuild --target=ppc --rebuild foo.src.rpm
