NixOS/patchelf: A small utility to modify the dynamic linker and RPATH of ELF executables

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

mkdir build
cd build
cmake .. -GNinja
ninja all
sudo ninja install

mkdir build
meson configure build
cd build
ninja all
sudo ninja install

You can build with Nix in several ways.

1. 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

2. 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
