Build with cargo build --release

Then, create a plugins directory (e.g. plugins) and copy c-plugin/add.wasm and js-plugin/subtract.wasm into that directory.

Finally, run (for example):

target/release/calculator --plugins plugins add 1 2 or target/release/calculator --plugins plugins subtract 1 2

For more details, see the "Calculator with WebAssembly Plugins" section of the documentation.
