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.

--set-interpreter INTERPRETER

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

--print-interpreter

Prints the ELF interpreter of the executable.

--set-rpath RPATH

Change the RPATH of the executable or library to RPATH.

--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.

--remove-needed LIBRARY

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

--debug

Prints details of the changes made to the input file.

--version

Shows the version of patchelf.
