@ViktorHofer, does it depend on dotnet/dotnet#2271?

ViktorHofer · 2025-11-29T12:02:56Z

Not necessarily but it would be better to get that in first. I included the branding update in this PR (see eng/Versions.props changes).

Bad use of words - meant the same thing.

I didn't find that change pushed in this PR. Did you tried it locally on some community platform? Could you show the command (or just push to branch so we can see the error in CI).

I didn't find that change pushed in this PR. Did you tried it locally on some community platform? Could you show the command (or just push to branch so we can see the error in CI).

I tried it locally on cross building freebsd. Same exact restore error.

am11 · 2025-12-05T21:35:50Z

I tested this patch am11@1cfe520 and built:

freebsd-x64: https://github.com/am11/CrossRepoCITesting/actions/runs/19975712524
using /runtime/build.sh -ci -arch x64 -os freebsd -cross -s clr+libs+host+packs -c Debug -rc Checked --keepnativesymbols true --bootstrap
linux-riscv64: https://github.com/am11/CrossRepoCITesting/actions/runs/19975681090
using /runtime/build.sh -ci -arch riscv64 -cross -s clr+libs+host+packs+tools.cdac -c Debug -rc Checked --keepnativesymbols true --bootstrap

both passed the restore and cDAC package build and later failing at ApiCompat stage.

The reason why I was asking you for the command or pushing the change because just like my workflow, runtime CI is also using --bootstrap for community platform along --cross arg and that's the only supported combination for community platform these days. It's documented by @jkoritzinsky in the link I shared above.

HostActivation.Tests "hanging" on MacOS - likely unrelated

Yep, unrelated: #122171 (comment)

jkoritzinsky · 2025-12-05T23:23:30Z

Looking at the patch, I believe @am11's patch is the right solution for the cDAC problem.

steveisok · 2025-12-06T04:01:16Z

both passed the restore and cDAC package build and later failing at ApiCompat stage.

I tried it both locally and I see @lewing pushed a change. Neither work.

The TargetFramework part of the change produces Ahead-of-time compilation is not supported for the target runtime identifier 'freebsd-x64'. That is a different message, but it's still tanking on restore.

lewing · 2025-12-06T04:06:31Z

#122258 has sdk branding flow which will make it easier to solve the remaining workload issues here but we will keep both up to date. dotnet/sdk#52031 is in progress for the sdk
.

am11 · 2025-12-06T13:51:22Z

@lewing, it turned out my branch was old, was based on older commit (which is why appcompat issue was present in my runs). Could you please apply:

am11@1dae2e4

it only affects community platforms and fixes the issue.

steveisok · 2025-12-06T16:26:13Z

am11@1dae2e4

Thanks for the suggestion. I think I understand why it was failing earlier. NetCoreAppToolCurrent isn't 11 and as a result, will skip

runtime/eng/targetingpacks.targets

Lines 19 to 23 in acfe981

    
             <PropertyGroup Condition="'$(DisableImplicitFrameworkReferences)' != 'true' and 
        
                                       '$(TargetFrameworkIdentifier)' == '.NETCoreApp' and 
        
                                       '$(TargetFrameworkVersion)' == 'v$(NetCoreAppCurrentVersion)'"> 
        
               <UseLocalTargetingRuntimePack Condition="'$(UseLocalTargetingRuntimePack)' == ''">true</UseLocalTargetingRuntimePack> 
        
             </PropertyGroup>

. That means it'll try to download the packs and can't.

If we try to change the TargetFramework to NetCoreAppCurrent, restore will fail because of some validation that produces Ahead-of-time compilation is not supported for the target runtime identifier 'freebsd-x64'. I think any solution to that needs to be done in a follow up.

jkoritzinsky · 2025-12-06T16:32:51Z

We should update the logic to always use the local packs when UseBootstrapLayout is true. Then it should do the "right thing".

am11 · 2025-12-06T17:23:31Z

Yup, that will resolve #115622 as well. :)

…ion upgrades It is tempting to read the version from an environment variable, but this breaks scenarios where we do a major version upgrade (e.g., net10.0 to net11.0) because we may be running the test build from an older runtime.
