@MehdiChinoune We only have the sysroot packaged but not the full wasi-sdk. Is packaging the full wasi-sdk feasible?

[ognevny]

wasi-sdk is actually wasi-libc+wasi-compiler-rt+wasi-libc++, so we need to add last 2 packages

[MehdiChinoune]

@ognevny wasi-libc++ is still missing.

[ognevny]

yeah I know...

[MehdiChinoune]

I think it will be useful to add all wasi package to a group called wasi-toochain (or wasi-sdk).
