patchelf - Modify ELF files
patchelf OPTION FILE ...
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.
The single option given operates on each FILE, editing in place. Any option taking a string argument can also take a file by prefixing the argument with the @ symbol. See EXAMPLES --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 RUNPATH Change the DT_RUNPATH of the executable or library to RUNPATH. --add-rpath RUNPATH Add RUNPATH to the existing DT_RUNPATH of the executable or library. --remove-rpath Removes the DT_RPATH or DT_RUNPATH entry of the executable or library. --shrink-rpath Remove from the DT_RUNPATH or DT_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". --allowed-rpath-prefixes PREFIXES Combined with the "--shrink-rpath" option, this can be used for further rpath tuning. For instance, if an executable has an RPATH "/tmp/build- foo/.libs:/foo/lib", it is probably desirable to keep the "/foo/lib" reference instead of the "/tmp" entry. --print-rpath Prints the DT_RUNPATH or DT_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 given 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 given multiple times. --remove-needed LIBRARY Removes a declared dependency on LIBRARY (DT_NEEDED entry). This option can be given multiple times. --no-default-lib Marks the object so that the search for dependencies of this object will ignore any default library search paths. --output FILE Set the output file name. If not specified, the input will be modified in place. --debug Prints details of the changes made to the input file. --version Shows the version of patchelf.
To use the contents on an external file as a parameter: $ patchelf a.out --add-rpath @/tmp/generated-rpath.bin To change the RPATH of a binary. Note that $ORIGIN is a special symbol used by the loader, so must be quoted. patchelf --set-rpath '$ORIGIN/../lib64' a.out
