[GSOC 2023] .NET Port

memsom · December 6, 2024, 11:44pm

What are you trying to do?

dotnet new console

That will create a console app in the current directory.

dotnet run

Should build and run the app

Nuget comes in to play when you want to add packages to expand the base functionality. You shouldn’t need to add any source or username if you are installing public packages from nuget.org. If you look on nuget.org, all packages list the commands to install the package, including the dotnet command line version.

For example, to add in the Newtonsoft.json package:

dotnet add package Newtonsoft.Json

Yes a simple app.

It’s not working on my side :

dotnet new console
The template "Console App" was created successfully.

Looks sus. Probably the code that’s trying to override the SDK versions in one of the manifest/.props files have gone wrong.

The versions released by my CI do not exactly match official versions.

Theoretically if you got all the SDK and runtime components in one place, they should be able to find each other.

Nexus-6 · December 7, 2024, 10:09am

I think there’s a mismatch between the SDK version and the nuget packages. Which version have you installed, 8 or 9?

Try this by providing your SDK version (8/9)

dotnet nuget add source --name dotnet9 "https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet9/nuget/v3/index.json"

EDIT: I’ve just seen you have v9 and changed the command accordingly

trungnt2910 · December 7, 2024, 10:21am

I really doubt installing public sources would help with locating SDKs for Haiku, since they’re not built by Microsoft.

Nexus-6 · December 7, 2024, 10:23am

This fixed the very same error I had when tried v8 for the first time. The problem seems to be on a specific nuget package.

DigitalBox · December 9, 2024, 9:46pm

Ok i’ve tried to reinstall from scratch following the page GitHub - trungnt2910/dotnet-builds: .NET binary builds for x86_64 Haiku

pkgman install -y gmp krb5 libiconv llvm12_libunwind mpfr
pkgman install -y jq # Required for the dotnet-install script.

Ok already installed

mkdir /boot/home/dotnet
bash -c "$(curl -fsSL https://raw.githubusercontent.com/trungnt2910/dotnet-builds/HEAD/dotnet-install.sh)" -- --install-dir  /boot/home/dotnet

Ok no error, however something strange about the user/group :

Is it expected ?

Now when launching dotnet :

 dotnet --version 
resolve symbol "pipe2" returned: -2147478780
Failed to load /boot/home/dotnet/shared/Microsoft.NETCore.App/9.0.1/libcoreclr.so, error: Symbol not found
Failed to bind to CoreCLR at '/boot/home/dotnet/shared/Microsoft.NETCore.App/9.0.1/'
Failed to create CoreCLR, HRESULT: 0x80008088

Library is there :

ls -l /boot/home/dotnet/shared/Microsoft.NETCore.App/9.0.1/libcoreclr.so
-rwxr-xr-x 1 messagebus 127 7473792 nov.   8 03:42 /boot/home/dotnet/shared/Microsoft.NETCore.App/9.0.1/libcoreclr.so

I might have miss a step somewhere in the installation ?

trungnt2910 · February 5, 2025, 9:22pm

Looks like you’re in an older version of Haiku than the one used by the builder on GitHub.

trungnt2910 · February 10, 2025, 2:24am

New pull request opened: #112323.

Let’s see if we can get things done in the .NET 10 cycle.

trungnt2910 · April 12, 2026, 6:51am

Status update for the port in 2026:

All code changes to the main dotnet/runtime repository for Haiku, as described in the final GSoC 2023 report, has been either merged or filed as pull requests. These PRs are being actively reviewed by the maintainers. You can find an overview of recent PRs here.
The .NET 10 release significantly complicated the build process, so I don’t think we will support .NET 10 release builds in the dotnet-builds repository.
Once all open PRs are merged, hopefully for .NET 11 because they aren’t that big and hard to review, I will try getting the builds running again. Right now, because of the maintainers’ request to split out the patches, there are too many patches on different branches that we have to stack on top of each other to get a successful build of the CoreCLR.

trungnt2910 · April 28, 2026, 10:55am

I somehow hacked through the .NET 10 build process, and we now have usable-ish .NET 10 builds:

Haiku is about to get Crossgen2/NativeAOT support: https://github.com/dotnet/runtime/pull/127431

One of the steps involved is to define a 16-bit magic OS-specific constant for Haiku to the PE binary format extension used by Crossgen2.

I am currently choosing 0x0B05 (a reference to OpenBeOS), but I think it might be better for us to decide this together as a community

PulkoMandy · April 28, 2026, 8:27pm

The historic value would be 5038 (which looks like BEOS if you look at it upside down on a calculator), maybe if it’s in hex, 0xBE05 works as well.

Unless there’s a plan to separately support BeOS, these should be fine?

trungnt2910 · April 28, 2026, 11:10pm

Cool, if there is a already official-ish source already using 5038 as an OS indicator, then we should follow.

Are there any examples of that in the wild?

I think there’s a higher chance of supporting .NET 11+ on Windows XP a BeOS port

waddlesplash · April 29, 2026, 4:09am

What do you consider “an official-ish source” and “the wild”? Would https://genius.com/The-cotton-squares-5038-lyrics count?

colmiga · April 29, 2026, 6:08am

I think using ‘5038’ would be a great nod to the past, given some of the band members worked for Be and the song was on the BeOS CD’s. Funny, I’ve listened to that song many times and it never occurred to me that it was ‘BeOS’ upside down, and I remember making words like that with a calculator as a kid.

Thanks for all the work in bringing .NET to Haiku, it’ll be great to have it available.

trungnt2910 · April 29, 2026, 7:27am

“official-ish” as in endorsed by Be/Haiku or their prominent representatives, and “the wild” as in mainstream cross-platform frameworks and formats comparable to PE.

Given this fact and that both @waddlesplash and @PulkoMandy strongly suggests 0x5038, then I guess it is decided

_SoulHunter · April 29, 2026, 7:38am

I personally like 0xBE05, it is a bit more obvious reference to BeOS than 5038.
Another reason, there is no confusion it is a hex number, unlike 5038 which could be incorrectly assumed to be decimal

x68k · April 29, 2026, 9:54am

0xBE05 looks a lot better than 5038, but it’s not my decision.

Akakor · April 29, 2026, 3:37pm

+1 for 0xBE05
