Error building the isf_demo example

[michaelmariaott]

Hello,

I have problems getting the isf_demo to build. I am on macOS 12.4 and get the following error:

[nannou_isf/src/pipeline.rs:504] &vs = Shader {
    source: HardCoded,
    module: Some(
        ShaderModule {
            context: Context {

            },
            id: (
                2,
                1,
                Metal,
            ),
        },
    ),
    error: None,
}

        },

Is this a problem with the render pipeline in nannou?

I'm seeing this too. It's not a build issue, it's a run time issue. As soon as it launches it crashes.

Same here :/ Macbook Air M1. Any ideas?
Thx, Teo

tagging @mitchmindtree as it seems they're the author of examples/isf/isf_demo.rs.

I haven't had a chance to continue work on this, but for some more context on the state of the ISF demo support, check out this long-running PR: #684.

I just ran into this today. I'm wondering if part of the issue is that nannou_isf depends on hotglsl, which depends on glsl-to-spirv. The glsl-to-spirv crate is deprecated in favor of the shaderc crate, and I actually encountered a build failure trying to create a Nix flake for this repository with the exact same error message seen here: vulkano-rs/vulkano#2318
