.NET bindings to the Haiku API

Nexus-6 · January 6, 2024, 5:14pm

It looks already promising, doesn’t it?

trungnt2910 · January 6, 2024, 5:24pm

The syntax highlighting looks great! If only we could port OmniSharp and some kind of .NET Core debugger…

Nexus-6 · January 6, 2024, 5:33pm

I’ll try with Omnisharp later tonight…

Maybe you know how to solve this:

First time seeing this error. Unfortunately, without further logs, I really don’t know. --verbosity detailed might help.

Getting more detailed logs shows a number of problems that occur with every single project I try to compile (for example Omnisharp and ILSpyCmd).

These occur trying to install packages via nuget under the form of:

error NU3037: The author primary signature validity period has expired.

and

error NU3028: The author primary signature's timestamping certificate is not trusted by the trust provider.

here’s an excerpt of the build log of ILSpyCmd:

I’ve found tons of posts around but none clarifies why this is happening. Is there an issue with the certificate validation in our .NET custom build?

trungnt2910 · January 8, 2024, 6:47am

I’ve actually encountered that error when trying to build dotnet from source on Haiku.

To be fair, the posts are not really related, but they did help me solve the problem.

No, this is an issue with the certificates that come with Haiku. You will need to add this certificate:

I guess it worked but I need to make further tests. Thanks!

On another topic… It seems that the layout family of classes have been produced in Haiku.dll but they do not have a public constructor (BLayout, BGroupLayout, BLayoutItem, etc.). Have these been disabled/not published for a reason?

trungnt2910 · January 8, 2024, 1:14pm

That seems sus, can you check if they even have private/protected constructors at all?

The Interface Kit has surely been generated, and these classes don’t seem to have been treated specially in any way.

Nexus-6 · January 8, 2024, 1:31pm

This is the code:

	public readonly BButton fButton;
	public readonly BStringView fStringView;
	private readonly uint kMsgButtonClick = 1;

    public MainWindow()
        : base(new BRect(), "Main Window", WindowType.TitledWindow, B_QUIT_ON_WINDOW_CLOSE)
    {
        MoveTo(100, 100);
        ResizeTo(400, 400);

		fStringView = new BStringView(new BRect(10, 10, 400 ,30), null, "BStringView");
		fButton = new BButton(new BRect(10, 50, 200, 30), null, "BButton", new BMessage(kMsgButtonClick));

		BGroupLayout group = new BGroupLayout(B_VERTICAL);
		SetLayout(group);
		group.AddView(fStringView);
		group.AddView(fButton);
    }

And here’s the build log:

Here’s what ILSpy detects:

You can clearly see that there are no public constructors, only private and protected.
I don’t expect to see the layout builders being them C++ templates, but BLayout related classes are plain C++ classes and should be definitely there, I think

trungnt2910 · January 8, 2024, 1:53pm

Don’t have my dev machine right now so I can’t run a full local build and debug stuff, but looking at the build logs, I can see the issue:

Incomplete class BLayout has no complete definition
[...]
Incomplete class BGroupLayout has no complete definition
[...]
Incomplete class BLayoutItem has no complete definition

This log is created here:

github.com

trungnt2910/dotnet-haiku/blob/1dde42d3ce515aea05b22c35d0910dcead6dfd13/generator/HaikuApiGenerator/Passes/ProcessIncompleteTypesPass.cs#L24C1-L30C10


      
          if (decl.IsIncomplete)
          {
              if (_astContext.FindCompleteClass(decl.Name) == null)
              {
                  Console.WriteLine($"Incomplete class {decl.Name} has no complete definition");
              }
          }

FindCompleteClass is a helper function provided by CppSharp:

github.com

mono/CppSharp/blob/9071cd2a591d5dcb5c584d2774f60905db12ce56/src/AST/ASTContext.cs#L86C1-L91C10


      
          /// Finds the complete declaration of a class.
          public Class FindCompleteClass(string name, bool ignoreCase = false)
          {
              return FindClass(name, ignoreCase: ignoreCase).FirstOrDefault(
                  @class => !@class.IsIncomplete);
          }

To properly debug this, one would need to run the generator on Linux. To run this, you will need to export the HAIKU_API_GENERATOR_ROOT_DIR variable to some cross-compile rootfs, such as the one provided by jessicah’s script. If you are already cross-compiling .NET or having HyClone, no additional configuration is needed, the generator will make use of these prefixes.

After running the project, we would need to inspect the syntax tree. Somehow, the generators missed the definitions, or maybe I have missed a few headers?

Nexus-6 · January 8, 2024, 3:54pm

I don’t have access to a linux machine and honestly don’t plan to fire one up.
What about MacOS instead? Do you think it would be a viable solution?

No, you have not.
The problem is more deep, the generator completely missed other classes: BLayoutContextListener, BAbstractLayout, BAbstractLayoutItem, BTwoDimensionalLayout, and many more.

trungnt2910 · January 8, 2024, 5:38pm

CppSharp should support macOS (as long as you’re not running M1). Browsing through the source code, I guess CppSharp should be built with ELF binaries support even on macOS.

The hard part for now would be getting a rootfs, though unlike HyClone, you won’t need everything: Just the system include and system library directories are enough. It should be possible to copy these using an scp from your Haiku setup.

OMNISHARP

I’ve managed to build and run OmniSharp not without a number of dirty hacks, but this is another story…

Now the problem is that MSBuildLocator fails in locating MSBuild although in theory OmniSharp should locate it automatically via SdkResolver. There are fallback options for VSStudio and Mono but they are not applicable.
Any thoughts why the SDK can’t resolve this path?

trungnt2910 · January 11, 2024, 6:42pm

What I understand from the logs is that the SDK is resolved, but the MSBuild version is wrongly detected.

How does OmniSharp detect the MSBuild version, and what did it discover?

Nexus-6 · January 11, 2024, 7:08pm

I solved this and now Omnisharp runs well (only the stdio server, the http flavour does not compile for some reason).
Unfortunately the LSP mode does not work, apparently there is a bug never fixed due to a lock in an async/await cal.
The version that comes with the vscode C# extension works though.
I’ll keep investigating…

Nexus-6 · January 12, 2024, 11:16am

I think this deserves a bit of celebration
OmniSharp up and running in LSP mode communicating with Genio!
They talk but don’t understand each other quite well at the moment. But we’ll get there!

Nexus-6 · January 16, 2024, 3:05pm

For those interested in the progress with Genio + OmniSharp, I’ve managed to get Completion, Hover and SignatureHelp work. Plus “Problems” and some formatting warnings.
