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.

NAME

       ldd_pa: ldd - list dynamic dependencies of executable files or shared libraries on PA-RISC systems

SYNOPSIS

       filename...

   Remarks
       This manpage describes on PA-RISC systems.  For on Integrity systems, see ldd_ia(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.  See and sections in dld.sl(5) for more information.

   Options
       recognizes the following options:

	      PA-RISC 32-bit only.
		   Used in conjunction with and/or to force to bind all dependent libraries and report unsats.	By default the smartbind mechanism
		   in only binds libraries whose symbols are explicitly referenced.

	      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.

       PA-RISC 64-bit mode:
	      A colon-separated list of path names which defines the search path for shared libraries at  runtime.   See  in  dld.sl(5)  for  more
	      information.

       A colon-separated or space-separated list of libraries which the dynamic
	      loader implicitly loads first at runtime.  See in dld.sl(5) for more information.

       A colon-separated list of path names which defines the search path for
	      shared libraries at runtime.  See and in dld.sl(5) for more information.

       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 causes to analyze all symbol references and print information about unsatisfied code and data symbols.

       The option causes to print the dynamic search path lists used to load the libraries in the order that the path lists are referenced:

WARNINGS

       does not list shared libraries explicitly loaded using dlopen(3C) or shl_load(3X).
