Unable to link mingw64 + rust nightly undefined reference to `__imp___acrt_iob_func'

[norru]

I am trying to compile https://github.com/vulkano-rs/vulkano on nightly.

OS: Windows 10 + mingw64, pacman -Syu to latest mingw64 from MSYS2
Toolchain: nightly-x86_64-pc-windows-gnu
rustc 1.35.0-nightly (bc44841ad 2019-03-14)

MINGW64 /f/Projects/3rdParty/vulkano
$ cargo build

error: aborting due to previous error

error: Could not compile `vulkano-shaders`.

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

Building on stable succeeds but I need nightly for development. Building on stable-*-msvc works.

The Vulkano readme states:

windows-gnu toolchain is not supported but you can instead cross-compile to windows-gnu from windows-msvc

so this looks like a user error to me, even if it did happen to work in the past?

Ah right, I missed that bit. Thanks.
