.SH 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.
|
||
|
|
|
||
|
|
.SH OPTIONS
|
||
|
|
|
||
|
|
The single option given operates on a given FILE, editing in place.
|
||
|
|
|
||
|
|
.IP "--set-interpreter INTERPRETER"
|
||
|
|
Change the dynamic loader ("ELF interpreter") of executable given to
|
||
|
|
INTERPRETER.
|
||
|
|
|
||
|
|
.IP --print-intepreter
|
||
|
|
Prints the ELF interpreter of the executable.
|
||
|
|
|
||
|
|
.IP "--set-rpath RPATH"
|
||
|
|
Change the RPATH of the executable or library to RPATH.
|
||
|
|
|
||
|
|
.IP --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".
|
||
|
|
|
||
|
|
.IP --print-rpath
|
||
|
|
Prints the RPATH for an executable or library.
|
||
|
|
|
||
|
|
.IP --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.
|
||
|
|
|
||
|
|
.IP --debug
|
||
|
|
Prints details of the changes made to the input file.
|
||
|
|
|
||
|
|
.IP --version
|
||
|
|
Shows the version of patchelf.
