The project compiles fine, but when trying to run tests or the sphere example, I've got those messages :

Might this be an issue with the version of Visual Studio I'm using ? I'm using nightly-x86_64-pc-windows-msvc rust toolchain.

AFAIK mvsc uses different ABI, so it's probably the reason. I'm not sure though

@vitvakatu exactly.

According to this: rust-lang/rust-bindgen#849, thiscall calling convention, used by msvc, is not yet implemented in rust.

So bindgen could generate bindings with --target=i686-pc-windows-msvc, but you will need some very nightly rust(not sure that it even exist) to use it. And anyway it will require a lot of work on rust side.

I decided to focus on gcc version and wait for bindgen and rustc improvements.

For now, I see only 2 options for you:

  • fork physics client C-API based version and use it with msvc
  • switch to x86_64-pc-windows-gnu

I really like the new c version, it's so much powerful and controllable, so I am into the second option :)

yeah, I really like the new version too. I have a few pull requests in the pipe. You can check them here. Only can't test them right now :) Ok, trying to switch to gnu toolchain

yeah, works fine with x86_64-pc-windows-gnu! closing this issue
