NAME

       patchelf - Modify ELF files

SYNOPSIS

       patchelf OPTION FILE

DESCRIPTION

       PatchELF is a simple utility for modifying existing ELF executables and libraries.  It can
       change the dynamic loader ("ELF interpreter") of  executables  and  change  the  RPATH  of
       executables and libraries.

OPTIONS

       The single option given operates on a given FILE, editing in place.

       --page-size SIZE
              Uses the given page size instead of the default.

       --set-interpreter INTERPRETER
              Change the dynamic loader ("ELF interpreter") of executable given to INTERPRETER.

       --print-interpreter
              Prints the ELF interpreter of the executable.

       --print-soname
              Prints  DT_SONAME  entry of .dynamic section.  Raises an error if DT_SONAME doesn't
              exist.

       --set-soname SONAME
              Sets DT_SONAME entry of a library to SONAME.

       --set-rpath RPATH
              Change the RPATH of the executable or library to RPATH.

       --remove-rpath
              Removes the DT_RPATH or DT_RUNPATH entry of the executable or library.

       --shrink-rpath
              Remove from the RPATH all directories that do not contain a library  referenced  by
              DT_NEEDED fields of the executable or library.

              For  instance,  if  an  executable  references  one library libfoo.so, has an RPATH
              "/lib:/usr/lib:/foo/lib", and libfoo.so can only be found in /foo/lib, then the new
              RPATH will be "/foo/lib".

       --print-rpath
              Prints the RPATH for an executable or library.

       --force-rpath
              Forces  the  use  of  the  obsolete  DT_RPATH in the file instead of DT_RUNPATH. By
              default DT_RPATH is converted to DT_RUNPATH.

       --add-needed LIBRARY
              Adds a declared dependency on a dynamic library (DT_NEEDED).  This  option  can  be
              give multiple times.

       --replace-needed LIB_ORIG LIB_NEW
              Replaces  a  declared dependency on a dynamic library with another one (DT_NEEDED).
              This option can be give multiple times.

       --remove-needed LIBRARY
              Removes a declared depency on LIBRARY (DT_NEEDED entry). This option can  be  given
              multiple times.

       --no-default-lib
              Marks  the  object  that the search for dependencies of this object will ignore any
              default library search paths.

       --debug
              Prints details of the changes made to the input file.

       --version
              Shows the version of patchelf.
