I have a minimal rust shader that just renders a triangle to the screen that I am compiling with an old wrapper around rust-gpu.
I am trying to compile the same shader with cargo gpu as:
cargo gpu build

Error: build failedI am within the crate folder when Invoke the command.
I am not entirely sure what the problem actually is. I know the crate has to be correct because it compiles with my custom wrapper.
the shader:
