A linker to create a Component from input object files and libraries.
This application is an equivalent of `wasm-ld` except that it produces a component instead of a core wasm module. This application behaves very similarly to `wasm-ld` in that it takes the same inputs and flags, and it will internally invoke `wasm-ld`. After `wasm-ld` has been invoked the core wasm module will be turned into a component using component tooling and embedded information in the core wasm module.
Usage: wasm-component-ld [OPTIONS] --output <OUTPUT> [objects]...
Arguments:
[objects]...
objects to pass to `wasm-ld`
Options:
--wasi-adapter <command|reactor|proxy|none>
Which default WASI adapter, if any, to use when creating the output component
--wasm-ld-path <PATH>
Location of where to find `wasm-ld`.
If not specified this is automatically detected.
--rsp-quoting <STYLE>
Quoting syntax for response files
-o, --output <OUTPUT>
Where to place the component output
--verbose
Print verbose output
--validate-component <VALIDATE_COMPONENT>
Whether or not the output component is validated.
This defaults to `true`.
[possible values: true, false]
--adapt <[NAME=]MODULE>
Adapters to use when creating the final component
--component-type <WIT_FILE>
WIT file representing additional component type information to use.
May be specified more than once.
See also the `--string-encoding` option.
--string-encoding <STRING_ENCODING>
String encoding to use when creating the final component.
This may be either "utf8", "utf16", or "compact-utf16". This value is only used when one or more `--component-type` options are specified.
[default: utf8]
--skip-wit-component
Skip the `wit-component`-based process to generate a component
-h, --help
Print help (see a summary with '-h')
-V, --version
Print version
