Issue compiling Bevy project on linux gnu cargo target

[Hellzbellz123]

pretty sure this is related too using simd-nightly feature of rapier2d, disabling that cargo feature got it too compile, however i noticed one strange issue between cranelift and rustc. the following line wouldnt compile with cranelift but would compile with the normal rustc codegen *wtransform.rotation = *(Quat::from_euler(EulerRot::ZYX, aimangle, 0.0, 0.0));

this is the output from trying to using rapier2d/simd-nightly

[Hellzbellz123]

i managed too have fat fingers my apologies, i managed to get the project to compile in release after disabling lto, not sure why the de-reference wasnt working with cranelift but removing the * fixed that compiler error, it works both ways in rustc so it shouldnt be too big of a deal

as for the simd-nightly errors, the simd-nightly feature of rapier is equivelant too this: simd-nightly = [ "simba/packed_simd", "simd-is-enabled" ]

simd-stable compiles fine so i think this issue was probably my fault?

[bjorn3]

I can reproduce this by compiling simba with the packed_simd feature.

[bjorn3]

Looks like simba depends on the packed_simd_2 crate from crates.io which has been subsumed by std::simd. packed_simd_2 uses a version of the interface with rustc that cg_clif doesn't support. There is an open issue to migrate to std::simd: https://github.com/dimforge/simba/issues/33 I'm going to close this as the right course of action is for simba to move to std::simd. For now using simd-stable with rapier is the best option.
