To learn more, run the command again with --verbose.

Looks like it might be as trivial as changing some u64's to usize's to fix.

Ah, might be a problem with the cocoa package. Will continue digging.

[yupferris]

As a quickfix, I tried some trivial casts at all of these locations (... as _) to fix up the types, but it was unable to bring up a window, and eventually crashed. My test project is spitting out tons of GL_INVALID_FRAMEBUFFER_OPERATION errors, but I doubt the specific error type is relevant here. Might be something deeper that needs to be done rather than just fixing up the types here.
