redo_prebinding

REDO_PREBINDING(1)					      General Commands Manual						REDO_PREBINDING(1)

NAME

       redo_prebinding - redo the prebinding of an executable or dynamic library

SYNOPSIS

       redo_prebinding	[-c  |	-p  |  -d] [-i] [-z] [-r rootdir] [-e executable_path] [-seg_addr_table table_file_name] [-seg_addr_table_filename
       pathname] [-o output_file] input_file

DESCRIPTION

       Redo_prebinding is used to redo the prebinding of an executable or dynamic library when one of the  dependent  dynamic  libraries  changes.
       The  input  file,  executable  or  dynamic  library,  must  have initially been prebound for this program to redo the prebinding.  Also all
       depended libraries must have their prebinding up to date.  So when redoing the prebinding for libraries they must  be  done  in	dependency
       order.	Also when building executables or dynamic libraries that are to be prebound (with the -prebind options to ld(1) or libtool(1)) the
       dependent libraries must have their prebinding up to date or the result will not be prebound.

       The options allow for different types of checking for use in shell scripts.  Only one of -c, -p or -d can be used at a time.  If  redo_pre-
       binding redoes the prebinding on an input file it will run /usr/bin/objcunique if it exists on the result.

OPTIONS

       -c     only  check if the file needs to have it's prebinding redone and return status.  A 0 exit means the file's prebinding is up to date,
	      1 means it needs to be redone and 2 means it could not be checked for reasons like a dependent library is missing (an error  message
	      is printed in these cases).

       -p     check  only  for prebound files and return status.  An exit status of 1 means the file is a Mach-O that could have been prebound and
	      is not otherwise the exit status is 0.

       -d     check only for dynamic shared library files and return status.  An exit status of 0 means the file is a dynamic  shared  library,  1
	      means the file is not, 2 means there is some mix in the architectures.

       -i     ignore non-prebound files (useful when running on all types of files).

       -z     zero out the prebind check sum in the output if it has one.

       -e executable_path
	      replace any dependent library's "@executable_path" prefix with the executable_path argument.

       -seg_addr_table table_file_name
	      The  -seg_addr_table  option  is	used when the input a dynamic library and if specified the table entry for the install_name of the
	      dynamic library is used for checking and the address to relocate the library to as it prefered address.

       -seg_addr_table_filename pathname
	      Use pathname instead of the install name of the library for matching an entry in the segment address table.

       -r rootdir
	      prepend the rootdir argument to all dependent libraries.

       -o output_file
	      write the updated file into output_file rather than back into the input file.

DIAGNOSTICS

       With no -c, -p or -d an exit status of 0 means success and 2 means it could not be done for reasons like a dependent library is missing (an
       error message is printed in these cases).  And exit of 3 is for the specific case when the dependent libraries are out of date with respect
       to each other.
