is darwin or ios possible ?

I always hit "undefined: getSurfaceDescriptor" issue. See below.

https://github.com/rajveermalviya/go-webgpu/blob/main/.github/workflows/ci.yml#L25 prevents CI testing darwin ?

[rajveermalviya]

I always hit "undefined: getSurfaceDescriptor" issue. See below.

yeah triangle & gio-windowing examples currently don't implement getSurfaceDescriptor for darwin (like for linux), though it can be easily implemented via SurfaceDescriptorFromMetalLayer, contributions welcome :).

though other examples (compute & capture) should be working.

prevents CI testing darwin ?

github actions runner doesn't have gpu & macos doesn't ship cpu based metal api implementation, so yeah

Hey @rajveermalviya

Yeah i saw the _linux.go version. and started to make _darwin version, but I could not work it out even with https://pkg.go.dev/github.com/rajveermalviya/go-webgpu/wgpu#SurfaceDescriptorFromMetalLayer. Sorry but i mostly do basic http stuff in golang.

DO you think you can write that code ?

I can test it at least locally here on my intel mac.

[gedw99]

though other examples (compute & capture) should be working.

Yes they did for me thanks.

[gedw99]

this might work for CI for Darwin and IOS, so i asked here: https://github.com/nektos/act/discussions/1143

[rajveermalviya]

I can test it at least locally here on my intel mac.

I have created a PR #115 which adds support for glfw based triangle example. Would appreciate if you can test it.

[gedw99]

it works

i can compile and run gio ios also if need be. If you get the gio window example working then it should work on ios i think. worth trying..

[rajveermalviya]

it works

thanks for testing :tada:

i can compile and run gio ios also if need be

it will first require ios builds of wgpu-native static libraries. will surely try too add them

[gedw99]

cool. I can't believe you were able to code the darwin triangle without a MacOS to try it on. Impressive dude !!

[rajveermalviya]

mostly thanks to zig cc's magic. setting correct env for gopls & it provides linting in vscode. it only goes as far as being able to build for macos on linux. still need a mac to run/test the binary.

[gedw99]

thanks - i am def going to check out that link when i have a second... I heard of zig, but never had a reason to look into it deeper.

Still amazing either way.

[gedw99]

hey @rajveermalviya

I just noticed there is an IOS lib now.

[gedw99]

Hey @rajveermalviya If you need MAC Testing again just let me know.
