Awesome, thanks. To reproduce, I just need need to checkout your allwpilib repo in bzlmodRio, latest version?

[pjreiniger]

Yeah that should definitely fail, at least on ci. I left it out of my comment, but I had --config=windows --enable_bzlmod in my user.rc.

I'm pretty sure it would fail with a bare bones hello world program too.

[AustinSchuh]

Agreed, this looks non-wpilib specific, and like a toolchain configuration problem.
