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. Apple Computer, Inc. September 10, 2001 REDO_PREBINDING(1)

ldd_ia(1) General Commands Manual ldd_ia(1) NAME
ldd_ia: ldd - list dynamic dependencies of executable files or shared libraries on Integrity systems SYNOPSIS
filename... Remarks This manpage describes on Integrity systems. For on PA-RISC systems, see ldd_pa(1). DESCRIPTION
is a command that can list the dynamic dependencies of incomplete executable files or shared libraries. lists verbose information about dynamic dependencies and symbol references. If the object file is an executable file, lists all shared libraries that would be loaded as a result of executing the file. If it is a shared library, lists all shared libraries that would be loaded as a result of loading the library. uses the same algorithm as the dynamic loader and to locate the shared libraries at runtime. See in dld.so(5) for more information. Options recognizes the following options: Check reference to data symbols. Check reference to data and code symbols. Display the search path used to locate the shared libraries. Display all dependency relationships. EXTERNAL INFLUENCES
Environment Variables uses the following environment variables to locate shared libraries. These environment variables can be used to specify the directories to be searched for library files at runtime. The value is a colon-separated list of paths of such directories. For more information, see in dld.so(5) or the option in ld(1). The following internationalization variables affect the execution of Determines the locale category for native language, local customs and coded character set in the absence of and other environment variables. If is not specified or is set to the empty string, a default of (see lang(5)) is used instead of Determines the values for all locale categories and has precedence over and other environment variables. Determines the locale that should be used to affect the format and contents of diagnostic messages written to standard error. Determines the locale category for numeric formatting. Determines the locale category for character handling functions. Determines the location of message catalogs for the processing of If any internationalization variable contains an invalid setting, behaves as if all internationalization variables are set to See envi- ron(5). DIAGNOSTICS
prints the record of shared library path names to stdout. The optional list of symbol resolution problems are printed to stderr. returns zero when the operation is successful. A non-zero return code indicates that an error occurred. EXAMPLES
By default prints a simple dynamic path information. This consists of the dependencies recorded in the executable (or the shared library) followed by the physical location where these libraries are found. The option causes to print dependency relationship along with the dynamic path information. The option to causes it to analyze all symbol references and print information about unsatisfied code and data symbols. WARNINGS
does not list shared libraries explicitly loaded using dlopen(3C) or shl_load(3X). FILES
