OpenHarmony: NativeAOT and pack integration by springmin · Pull Request #136185 · dotnet/runtime

springmin · 2026-10-20T22:52:31Z

Summary

Wire the openharmony-* RIDs through the NativeAOT, crossgen2, pack and
ILLink build paths: map openharmony to Linux in the shared target-OS parser,
keep the CoreLib and runtime packs ReadyToRun like the other Unix targets, use
the NDK's lld and ohos ABI, keep the musl libc flavor in the SingleEntry
layout, list the RIDs in the local pack graphs, and select the managed NTLM
implementation.

Changes

src/coreclr/tools/Common/CommandLineHelpers.cs: accept openharmony and
map it to TargetOS.Linux, same as android.
src/coreclr/nativeaot/BuildIntegration/Microsoft.NETCore.Native.Unix.targets:
select lld for openharmony, set CrossCompileAbi to ohos
(aarch64-linux-ohos), and skip System.Net.Security.Native (no
gssapi/krb5 in the sysroot).
.../Microsoft.DotNet.ILCompiler.SingleEntry.targets: keep the musl libc
flavor for openharmony; the target OS name is accepted through the shared
mapping.
eng/targetingpacks.targets: add openharmony-arm64 and openharmony-x64
to the local runtime, NativeAOT and apphost RID lists; replace the
SDK-provided apphost pack entry with the local one; scope the
ResolvedRuntimePack local-pack override to the target RID on OpenHarmony.
src/native/eventpipe/ds-portable-rid.c: report openharmony as
PORTABLE_RID_OS.
.../Microsoft.NET.ILLink.targets: use the managed NTLM implementation on
OpenHarmony (no GSSAPI/krb5 in the sysroot), like linux-bionic.
Six files, 25 insertions and 6 deletions.

Impact

OpenHarmony only. The new conditions are inert for every other target; the
existing linux, android/bionic, Apple and BSD paths are unchanged.
The CoreLib and runtime packs stay ReadyToRun like the other Unix targets;
there is no IL-only special case.
The openharmony RIDs are listed on the CoreCLR and NativeAOT packs only, not
on the Mono-labelled pack: the port is CoreCLR+NativeAOT.
No pack is shipped from this PR; it only teaches the local build graph about
the RIDs.

Test

Cross-build for openharmony-arm64: crossgen2 accepts
--targetos openharmony (mapped to Linux) and the CoreLib/runtime pack are
ReadyToRun.
NativeAOT publish for openharmony-arm64: ilc invokes the NDK clang with
--target=aarch64-linux-ohos and links with lld; the SingleEntry layout
uses the musl libc flavor.
Local-pack build for openharmony-arm64: runtime, apphost and ILCompiler
artifacts are produced, and the ResolvedRuntimePack override is scoped to
the target RID.
ILLink on an openharmony-* RID selects the managed NTLM implementation.

- target OS: map openharmony to Linux in the shared CommandLineHelpers parser, so crossgen2 and ilc accept the RID without local mappings. - crossgen2/packs: keep the CoreLib and runtime packs ReadyToRun like the other Unix targets; drop the IL-only special case and its pdb dedup workaround. - NativeAOT: use lld and the ohos clang ABI on OpenHarmony, and keep the musl libc flavor in the SingleEntry layout. - packs: add openharmony-arm64/x64 to the local runtime, NativeAOT and apphost pack RID lists, and emit the openharmony portable RID. - ILLink: use the managed NTLM implementation on OpenHarmony.

All six points are addressed in 7ce2047: openharmony is mapped to Linux in the shared CommandLineHelpers parser, the CoreLib and runtime packs are ReadyToRun (no IL-only special case or pdb dedup target), and the comment / _targetOS nits are fixed. CI will validate the build.

Note

This comment was drafted with AI assistance (agent tooling) under the author's direction.

Enabled R2R for the OpenHarmony CoreLib/runtime packs, added the shared openharmony->Linux mapping, removed the local crossgen2 mappings and the unneeded comments, and switched the linker condition to _targetOS. Head 7ce2047 (6 files 25+/6-); all six inline threads answered.

Reverting the OpenHarmony TFM special casing leaves an empty diff; the standard TargetOS TFM path works like FreeBSD. Replied to jkotas and closed the PR. Runtime in flight: dotnet#136185, dotnet#136194, dotnet#136198.

Update the existing KnownAppHostPack entry with the local RIDs and version instead of removing it, and scope ResolvedRuntimePack to the target RID for every OS; only the Include fallback remains for SDKs without the entry.

springmin · 2026-10-21T03:09:06Z

Updated in 127135f: the apphost pack uses Update (with the Include fallback when the SDK has no entry) and ResolvedRuntimePack is scoped to the target RID for every OS. The official RID lists (runtime OfficialBuildRID + the SDK list) remain the follow-up once the OpenHarmony cross-build image (dotnet-buildtools-prereqs-docker#1778) and the CI leg exist.

Note

This reply was drafted with AI assistance (agent tooling) under the author's direction.

Use _LocalAppHostRuntimeIdentifiers for the runtime, NativeAOT, ILCompiler, Crossgen2 and apphost lists. The property holds the union of the local RIDs; extra RIDs in a list are harmless.

The SDK's Mono KnownRuntimePack already lists wasi-wasm, so the update that appended it is no longer needed. Keep the framework reference update, whose SDK list still omits wasi-wasm.

The shared local list includes OpenHarmony RIDs, which are CoreCLR/NativeAOT only; using it for the Mono runtime pack makes the Mono build fail. Keep the Mono-specific list (with wasi-wasm added) and use the shared list in the framework reference update.

…phost update Move the KnownFrameworkReference update below its include and give the KnownAppHostPack update the same identity/TFM filter as the framework reference update.

jkotas · 2026-10-21T16:18:34Z

There is still a build break on Mono: The runtime pack for Microsoft.NETCore.App.Runtime.Mono.browser-wasm was not downloaded. Try running a NuGet restore with the RuntimeIdentifier 'browser-wasm'.
