```

macOS:

```

$ install_name_tool -add_rpath $(stack path --local-install-root)/lib test

$ ./test

```

Linux:

```

$ export LD_LIBRARY_PATH=$(stack path --local-install-root)/lib:$LD_LIBRARY_PATH

$ ./test

```

Windows (MINGW):

```

$ export PATH=$(cygpath -u $(stack path --local-install-root))/lib:$PATH

$ ./test

```

## Usage with `cabal-install`

$ cabal build

$ cabal exec -- gcc test.c -Ilib -L$(dirname $(cabal list-bin example)) -lexample -o test

```

macOS:

```

$ install_name_tool -add_rpath $(dirname $(cabal list-bin example)) test

$ ./test

```

Linux:

```

$ export LD_LIBRARY_PATH=$(dirname $(cabal list-bin example)):$LD_LIBRARY_PATH

$ ./test

```

Windows (MINGW):

```

$ export PATH=$(cygpath -u $(dirname $(cabal list-bin example))):$PATH
