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.
