error: unexpected token get_local. (get_local $lhs)

when I try to use the wat2wasm file.wat command into a simple example like this, it gives me error.

(module
(func $add (param $lhs i32) (param $rhs i32) (result i32)
get_local $lhs
get_local $rhs
i32.add)
(export "add" (func $add))
)

This is the error:

add1.wat:3:5: error: unexpected token get_local, expected ).
    get_local $lhs
    ^^^^^^^^^
add1.wat:4:5: error: unexpected token get_local.
    get_local $rhs

wat2wasm add.wat cmd should run successfully. use one of the wabt tools to generate a wasm module from it
Solution

  • get_local token statement line has to be inside a separate parenthesis, like this:

    (module
  (func $add (param $lhs i32) (param $rhs i32) (result i32)
    (local.get $lhs)
    (local.get $rhs)
    (i32.add)
  )
  (export "add" (func $add))
)
