alexcrichton labeled issue #2269:

Building for FreeBSD results in compile_error!("unsupported platform")

Feature

Support for FreeBSD

Benefit

FreeBSD as an OS that has long supported pthread, kqueue, flexibility for compiler preferences, sandboxing, VMs (QEMU) and multiple architectures (ARM). Recently I've found that its stable as a VM on macOS. I personally find it easy to use for testing and it gives me another platform to test against which has exposed otherwise-unseen bugs.

Implementation

Trap handlers need to be updated and there are tests involving return values that usually fail.

Bumping on this one, when trying to build (from main or latest release source), under FreeBSD 13.1-RELEASE-p3 GENERIC amd64, it fails with:

error: could not compile `ittapi` due to 22 previous errors

Is there some depedency missed? Doing the same build. under the same FreeBSD version, but aarch64/arm64 - compile is fine (with one patch needed, but that's not relevant here) ?

edit: using newest ittapi sources (that include FreeBSD binding) compile fine, but that require some manual copying/patching.

Can we resolve this issue by bumping the version of the ittapi crate? (If not, I may have to release a new version of that crate which I am happy to do).

I haven't saw new verison of this crate with changes needed to compile - I did "copy over" from latest main and changes checksumsa to match and build

I published a new version of the ittapi crate yesterday, v0.3.3, that enables FreeBSD support. If you bump that dependency in Wasmtime I think things should work?

/bump

I run FreeBSD 13.1, as well. Has there been any movement on this?

TIA.

I think #5606 closed this issue. I'll close it and we can re-open a new one if there are other issues.
