install_name_tool

INSTALL_NAME_TOOL(1)					      General Commands Manual					      INSTALL_NAME_TOOL(1)

NAME

       install_name_tool - change dynamic shared library install names

SYNOPSIS

       install_name_tool [-change old new ] ... [-rpath old new ] ... [-add_rpath new ] ... [-delete_rpath new ] ... [-id name] file

DESCRIPTION

       Install_name_tool  changes the dynamic shared library install names and or adds, changes or deletes the rpaths recorded in a Mach-O binary.
       For this tool to work when the install names or rpaths are larger the binary should be built with  the  ld(1)  -headerpad_max_install_names
       option.

       -change old new
	      Changes  the dependent shared library install name old to new in the specified Mach-O binary.  More than one of these options can be
	      specified.  If the Mach-O binary does not contain the old install name in a specified -change option the option is ignored.

       -id name
	      Changes the shared library identification name of a dynamic shared library to name.  If the Mach-O binary is not	a  dynamic  shared
	      library and the -id option is specified it is ignored.

       -rpath old new
	      Changes  the  rpath  path  name old to new in the specified Mach-O binary.  More than one of these options can be specified.  If the
	      Mach-O binary does not contain the old rpath path name in a specified -rpath it is an error.

       -add_rpath new
	      Adds the rpath path name new in the specified Mach-O binary.  More than one of these options can be specified.  If the Mach-O binary
	      already contains the new rpath path name specified in -add_rpath it is an error.

       -delete_rpath old
	      deletes  the  rpath  path  name old in the specified Mach-O binary.  More than one of these options can be specified.  If the Mach-O
	      binary does not contains the old rpath path name specified in -delete_rpath it is an error.
