where `/path/to/mold` is an absolute path to `mold` exectuable.
Please make sure you have installed `clang`.
If you want to use mold for all projects, put the above snippet to
`~/.cargo/config.toml`.
If you are using GCC 12.1.0 or later, installing `clang` is not necessary.
The Cargo configuration snippet above can be simplified to the following:
where `/path/to/mold` is an absolute path to `mold` exectuable. In the
above example, we use `clang` as a linker driver as it can always take

```toml
[target.x86_64-unknown-linux-gnu]
rustflags = ["-C", "link-arg=-fuse-ld=mold"]
rustflags = ["-C", "link-arg=-fuse-ld=/path/to/mold"]
```
If you want to use mold for all projects, put the above snippet to
`~/.cargo/config.toml`.
If you are using macOS, you can modify `config.toml` in a similar manner.
Here is an example with `mold` installed via [Homebrew](https://brew.sh).
