This is by design currently. Binaryen won't support MinGW until their next release, so we needed to patch their code at the v95 tag and ship archives with this release. We only have access to Windows, Linux and Mac 64-bit through GitHub Actions to create these, so that's all we can support with v0.4.0.

We have a tracking issue at grain-lang/binaryen.ml#38

I am going to merge. If we decide to mark it as unavailable on those archs we can update the metadata in a separate PR

[phated]

Thanks! I actually don't know how to specify the platforms in the metadata. Is it somewhere in the docs?

[mseri]

Yes, one could do something like

opam-repository/packages/mirage-entropy/mirage-entropy.0.4.1/opam

Lines 36 to 38 in a78d7fa

	available:
	arch = "arm" | arch = "x86_32" | arch = "x86_64" | arch = "x86_64" |
	arch = "arm64"
