Description Julius 2020-08-12 15:09:28 UTC

The ebuild only enables the default features, but wasmer for some reason enables none of the backends by default, thus the built binaries cannot execute any wasm and are useless.

(The additional kwasmd binary immediately panics with "Kwasm loader is not enabled during compilation.")

Reproducible: Always

Steps to Reproduce:
1. emerge =dev-util/wasmer-0.11.0
2. acquire some random test file, e.g. https://github.com/wasmerio/wasmer/blob/be9da7278ba52d3790a339dfa656508d8d6acf12/tests/wasi_test_resources/snapshot1/hello.wasm
3. run wasmer hello.wasm
Actual Results:  
error: 'cranelift' isn't a valid value for '--backend <backend>'
	[possible values: ]

Expected Results:  
Hello, world!
