@dotnet/samsung Could you please take a look? These changes may be related to riscv64.

am11 · 2025-07-08T20:57:47Z

@dotnet/samsung, @filipnavara, FYI. I haven't tested it with dotnet/diagnostics repo (libSOS lldb plugin) yet. But it would be easier to fine tune it once the bulk of change is in. Good thing is that it's an independent component at the moment, future replacement for existing/classic DAC.

cDAC implementation looks good module comments. I don't have as much insight into the build changes.

Thanks for adding this!

/runtime/.dotnet/sdk/10.0.100-preview.6.25315.102/Sdks/Microsoft.NET.Sdk/targets/Microsoft.PackageDependencyResolution.targets(266,5): error NETSDK1047: Assets file '/runtime/artifacts/obj/Mono.Linker/project.assets.json' doesn't have a target for 'net10.0/linux-riscv64'. Ensure that restore has run and that you have included 'net10.0' in the TargetFrameworks for your project. You may also need to include 'linux-riscv64' in your project's RuntimeIdentifiers. [/runtime/src/tools/illink/src/linker/Mono.Linker.csproj]

This NETSDK1047 is being raised intermittently with live linker (sometimes freebsd-x64 bootstrapped fails, other times linux-riscv64 or loongarch64). I found a conversation between @ViktorHofer and @jkoritzinsky #92826 (comment), perhaps removing this global property:

src/native/managed/subproject.props:        <SubprojectProps Include="RuntimeIdentifier" Value="$(TargetRid)" />

may help? I checked Mono.Linker.csproj's project.assets.json generated under obj/ dir, it sometimes have net10.0/linux-loongarch64 (or riscv64 etc.) at the point cDAC is published (when it passes), other times it doesn't have the RID node in that JSON file. Without importing live linker targets, it fails due to the missing PrepareForILLink target. We can hack this target as well. I'm not sure what's the proper way to address it.

@jkoritzinsky I tried a few more things (e.g., setting HasRuntimeOutput=false), but it didn’t help; three out of five builds are still failing. In CI, the failing bootstrap leg varies from run to run (sometimes riscv64, sometimes loongarch64, sometimes freebsd), so it seems to be intermittent rather than tied to a specific bootstrap platform.

If you have other ideas to make Mono.Linker.csproj restore more reliable, please let me know, or feel free to push commits directly to the PR branch.

am11 · 2025-09-05T21:53:58Z

Use the right property name (really wish this was better doc'd

Thanks a lot @jkoritzinsky! Six repeated builds passed (earlier three out of five builds were failing).

Can we test this change in dotnet/dotnet before merging the PR? We saw two issues earlier:

[main] Source code updates from dotnet/runtime dotnet#1392 (comment) P2P ref fails, I think we will need to separate cDAC _inbuild and _published csprojs same as ilc / cg2 to satisfy the matrix.
Punt on cdac transport pack for linux-musl dotnet#1464 something in linux-musl cDAC package fails, most likely linux vs. linux-musl in path but it's a guess since the PR description didn't specify the error it was fixing. Perhaps we can run specific CI leg which failed to find out the details.

jkoritzinsky · 2025-09-16T23:09:39Z

@am11 for 1) I would expect that doing the same GlobalPropertiesToRemove trick would work.
for 2) I'm unsure and I'd rather defer that to the cdac folks to figure out when they're shipping if we can.

JulieLeeMSFT · 2025-10-13T16:39:21Z

@max-charlamb, PTAL.
CC @steveisok.

am11 · 2025-10-15T16:43:38Z

Builds at dotnet/dotnet#2512 are passing. System.Net failures are unrelated (likely due to some recent change; failing on other recent runs as well).
