Hi everyone. 👋

Currently I'm working on D binding for sokol project (truly a dual bindgen [sokol-tools, sokol-header]) which could be merged into the upstream project.

Up to now, my "ideal" configuration has been to run all the ported examples (from other supported bindings) on Drt or betterC provided @safe has DIP1000 enabled (not obligatory).

Except for the "clear" example (no have structs) works, the rest of the examples have partial execution, without 2D/3D animations, like the original ported examples.

e.g.:
https://github.com/kassane/sokol-d/blob/main/src/examples/sgl_context.d

Based on the articles in the official documentation, I tried to use __gshared (no @safe) to attribute both the display and offscreen structures inside state, but it didn't work.

@disable struct State
{
    @disable this();
    @disable this(this);
    __gshared Display display;
    __gshared Offscreen offscreen;
}
static assert(!__traits(isDisabled, State));
static assert(!__traits(isCopyable, State));

Reproduce

Expected

Use https://renderdoc.org/ and check and compare frames for both your working and non-working example

That'll give you an idea at what could be wrong

I suspect you have a typo in one of your definition

I'll try to take a look later

Sorry if I sidetrack the discussion, but I was amazed by the Zig build file in that project: https://github.com/kassane/sokol-d/blob/main/build.zig

Do you have more information about how to integrate C and D using Zig as the build tool?? That sounds very interesting.

Nice!! I'll try.

I don't doubt it. I'm experiencing D in just a week. (Newbie)😅

Hi Renato,

I'm glad you liked it. This is an experiment, as I haven't adapted to the dub yet.

Zig's goal at this point is to share libsokol configurations and replicate in the D compiler (currently, ldc2 only). If you want to see the result, just run zig build clear --verbose.

<Zig build> -> build(exe) -> build libsokol -> (optional) zigcc-wrapper -> build D example (using libsokol config) -> switch (cc/linker system or zigcc) -> binary (exe/lib)

I added some comments to build.zig explaining each point. If you have any questions, you can ask in the repo.
I saw that you are a MacOS user, I suggest you see issue/1 [closed] focused on zigcc wrapper.

TODO: It is intended to add dub support and will continue with Zig build-system support, including zig-pkg(v0.12.0/master - git url) for downloading and integrating C and D packages.

I debugged some existing bindings, and despite any user-level errors (via code) there's some conflict between ABIs.

In fact, it's mentioned by sokol's author below:

I managed to compile your project, sgl_context is working for me, it renders and roate

I had to remove this from your build script tho:

try cmds.append(b.fmt("--mcpu={s}", .{lib.target.getCpuModel().name}));

Otherwise it crashes

Wow! Cube and blend work, too?

And on my machine it doesn't rotate, just like I initially posted.

Please! This deserves opening an issue about it. Because Zig is normally set native build by default.
What version of LDC is used? 1.35?

Finally fixed!! Works in, linux/macos/windows/wasm32(need emsdk)

I was having trouble with the floating/double init (nan) and solved this issue by giving default values to structs fields.
