# RPatchO

Tool for patching dylibs for making use of an rpath setup for bundled distribution.

Normalizes the `LC_ID_DYLIB` of the dylib to allow for bundled distribution. Adjusts all `LC_LOAD_DYLIB` commands that load a non system library to make use of the `rpath`. Adds a `LC_RPATH` that points to the provided path.

### Setup

```

pip3 install -r requirements.txt

```

### Running

The first parameter is the rpath we want to use in the bundle. Commonly "@loader_dir/../Frameworks" is the right choice.

The second parameter is the library we want to mutate. Note: Modifications are done in place - create backups before running!

```

python3 rpatcho.py "@loader_dir/../Frameworks" libtest.dylib

```

### Validation

Use `otool` for getting the load commands.

```

otool -l libtest.dylib

```

Make sure the dylib filename matches the `LC_ID_DYLIB` filename portion - adjust the dylib filename to match if needed.
