PatchELF is a simple utility for modifying existing ELF executables and libraries. In particular, it can do the following:
Change the dynamic loader (“ELF interpreter”) of executables:
$ patchelf --set-interpreter /lib/my-ld-linux.so.2 my-program
Change the RPATH of executables and libraries:
$ patchelf --set-rpath /opt/my-libs/lib:/other-libs my-program
Shrink the RPATH of executables and libraries:
$ patchelf --shrink-rpath my-program
This removes 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.
In addition, the --allowed-rpath-prefixes option 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. To accomplish that, use:
$ patchelf --shrink-rpath --allowed-rpath-prefixes /usr/lib:/foo/lib my-program
Remove declared dependencies on dynamic libraries (DT_NEEDED entries):
$ patchelf --remove-needed libfoo.so.1 my-program
This option can be given multiple times.
Add a declared dependency on a dynamic library (DT_NEEDED):
$ patchelf --add-needed libfoo.so.1 my-program
This option can be give multiple times.
Replace a declared dependency on a dynamic library with another one (DT_NEEDED):
$ patchelf --replace-needed liboriginal.so.1 libreplacement.so.1 my-program
This option can be give multiple times.
Change SONAME of a dynamic library:
$ patchelf --set-soname libnewname.so.3.4.5 path/to/libmylibrary.so.1.2.3
./bootstrap.sh ./configure make make check sudo make install
You can build with Nix in several ways.
Building via nix build will produce the result in ./result/bin/patchelf. If you would like to build patchelf with musl try nix build .#patchelf-musl
You can launch a development environment with nix develop and follow the autotools steps above. If you would like to develop with musl try nix develop .#musl
