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 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".
|--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 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 dependency 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.|
