rapier3d doesn't compile with simd-nightly

[cybersoulK]

rapier3d = { version = "0.19.0", features = ["simd-nightly"] }

I have been patching rapier3d 0.18.0 with the following:
simba = { git = "https://github.com/dimforge/simba", branch = "master" } #fixes packed_simd2 dep

but since recently, it stopped working and it can't compile. Including rapier 0.19.0

forgot to say. My machine target is arch64, haven't tested with other targets.

Thanks for providing context, the linked comment helps understanding we have to migrate from packed_simd to std::simd in simba. Existing issue in simba: dimforge/simba#33

@cybersoulK I think this works now in rapier 0.21 since 3004a7d updated simba.

@cybersoulK I think this works now in rapier 0.21 since 3004a7d updated simba.

no, the issue has not been fixed yet. (0.21)
It needs to implement std::simd, and i don't see it yet.
(not sure what happened when i tested it, but it works now)

@cybersoulK In simba, the recent release removed the packed_simd feature and suggested using the portable_simd feature.

If you look in samba's src/simd/portable_simd_impl.rs, you'll see that it is using std::simd.

Further, compiling current parry with a nightly compiler and --features simd-nightly works for me.

i can confirm that both of these work:

rapier3d = { version = "0.21.0", features = ["simd-nightly"] }
rapier3d = { version = "0.22.0", features = ["simd-nightly"] }

thank you! i will close the issue
