Panic on an any example

[legendiguess]

Maybe i should install something additional?
Steps that i do:

1. clone repository
2. cd kas-wgpu
3. cargo run --exmaple example name

Also when i compiled it, some crate require to install cmake, so, i think, you should mention it in some installation guide.

All it was on a linux peppermint 10. Also using last nightly linux gnu toolchain.

Thanks for testing. The steps sound about right, unfortunately I can't tell what's wrong from that error message.

Can you try enabling the backtrace as mentioned (export RUST_BACKTRACE=1), and then copying the error into a gist please?

Aha, probably CMake is required for the GLSL compiler. Okay, I'll add a note 👍

Looks like it is wgpu::Adapter::request which fails. What GPU / integrated graphics do you have?

The disadvantage of using a modern graphics API as the first and only draw backend is that we don't have any other options (yet). Can you try running the GFX examples and see whether any backends are functional (e.g. gl)?

I will improve the error message here, but don't expect to have a CPU-based renderer soon.

I have Intel HD Graphics 500. Just checked gfx examples with different backend - only gl works.

Sounds like this issue: gfx-rs/wgpu#115 — i.e. eventually wgpu should support OpenGL / WebGL backends.

I improved error handling within kas_wgpu: e13f1d6

In combination with gfx-rs/wgpu#408 this should improve error messages.

Actually getting things working is rather more work...

I opened #33 to track support for additional targets.

The error message is improved, so I believe this can be closed.
