Linux UE builds failed on the Core wrapper module: the Linux-only PerModuleInline.gen.cpp saw Standalone/Compat
shadow headers instead of the engine's, and WITH_EDITOR was redefined under -Werror. Compat headers now forward
to the engine headers with include_next for generated Linux module TUs (canonical Core TUs opt into the Compat
definitions via CoreNamespacePreamble.h); CoreMinimal.h undefines WITH_EDITOR first. VoxelForgeCore.Build.cs
enables that forwarding and AVX2 on Linux only; VoxelForge.Build.cs disables Unity on Linux only. Portability:
std::int64_t consistently in VoxelContentManager.cpp; grouped &&/|| in VoxelRedefinedDensityField.cpp. Linux-only
trace fields split Core generateTile / mesh copy / RMC stream build. Standalone Clang and GCC whole-view hashes
are unchanged vs 3202193. The Unreal spawn trace is blocked by the owner's new assets (SW route sweep fails).

# Linux65 report
|
||
|
||
Date: 2026-10-26. No commit, push, or stash was made. The pre-existing untracked `Linux18/exports/` was left alone.
|
||
|
||
## Linux Unreal build
|
||
|
||
UE 5.7.4 / bundled Clang 20 builds pass with zero errors. The clean HEAD build completed 78 actions in 93.54 s; L14 (`a176d07`) completed 157 actions in 170.69 s. Final incremental builds after the Linux-only trace timing guards also pass. Logs are `Saved/Linux/l65/head-build5.log`, `l14-build1.log`, `head-build-final.log`, and `l14-build-final.log`.
|
||
|
||
Builds used CPUs 0–11, a 6 GiB RSS limit, at most 8 actions, AVX2, and `-NoUBA`. UBA stalled before starting compiler actions. Three existing RMC deprecation warnings remain: two `RemoveSectionGroup` calls and one `CreateSectionGroup` call in `VoxelWorld.cpp`.
|
||
|
||
Fixes:
|
||
|
||
- The Compat wrappers now forward to UE headers with `include_next` for generated Linux module TUs. `CoreNamespacePreamble.h` opts canonical Core TUs into the Compat definitions. `CoreMinimal.h` undefines `WITH_EDITOR` before defining the standalone value.
|
||
- `VoxelForgeCore.Build.cs` enables that forwarding and AVX2 only on Linux. `VoxelForge.Build.cs` disables Unity only on Linux to avoid duplicate anonymous test helpers.
|
||
- `VoxelContentManager.cpp` uses `std::int64_t` consistently; `VoxelRedefinedDensityField.cpp` groups the mixed `&&`/`||` expression.
|
||
- Linux-only trace fields measure Core `generateTile`, mesh copy, and RMC stream-set construction. The `PLATFORM_LINUX` guards keep Windows worker behavior and trace JSON unchanged.
|
||
|

||
## Unreal spawn trace
|
||
|
||
The U1 trace is `Tools/TestVoxelForgeCoreWorldHost.ps1 -TimeoutSeconds 900 -CoreVoxelSizeCm 25 -StreamingTraceOnly`. It runs `UnrealEditor-Cmd -run=VoxelForgeExplore` with `-coreworldtest=1`, `-coreworldstreamtrace=1`, `/Game/VoxelForge/DA_Settings.DA_Settings`, seed 0, 25 cm Core voxels, 600 cm/s movement, and the Legacy/default streaming flags. It creates a transient `UWorld`; no map is loaded.
|
||
|
||
The exact pre-U2 owner packages are unavailable in this Linux workspace. Both hosts used identical copies of the five current `/home/jahni/VoxelM/DA_*.uasset` files (post-U2), with matching SHA-256s in both projects:
|
||
|
||
| Asset | SHA-256 |
|
||
|---|---|
|
||
| `DA_Settings` | `8abe8243104980260feca0a6f4cf4927768e8e568221a6f6a2c2694f6d15d454` |
|
||
| `DA_Strate1` | `a9ca6cddd102250a893e379350b1d0f4aaf04c4f7fca70e0db46052a067d2cfb` |
|
||
| `DA_Strate2` | `8f9a12a3181635149e6f79f192e0ddaf6b6577442ee324071a7749dcc78b9a0c` |
|
||
| `DA_Strate3` | `5470d538c3c5e88237463e71bca9e2eb170dfe3a0543c0f33298d9fb010fd2f9` |
|
||
| `DA_Strate4` | `a98e33e1cd42f374d6cb70f5071e8ebba74d91ed59d2fd3201782dab84d28f5c` |
|
||
|
||
The minimal host lacked the two First Person Blueprints used by the commandlet's speed fixture. Stock UE template copies also lacked a valid sprint graph, so the isolated trace build trees used the test's established 600/6000 speed defaults only for `-StreamingTraceOnly`; no tracked source was changed for this workaround. The trace loop itself takes its 600 cm/s movement value from the command line.
|

|

|
||
Both commandlets stop before spawning `AVoxelWorld` with the same error: `SurfaceWorld route candidates failed the capsule and support sweep.` No tile trace file was produced. Thus this run cannot identify the Windows worker-time regression or separate Core generation from Unreal packaging. The failure is consistent across L14 and HEAD, but whether the post-U2 asset set or the route audit itself is responsible is unresolved; no fix is justified from this run.
|
||
|
||
L14 was exported from `a176d07` to the requested `Saved/Linux/l65/l14tree/Plugins/VoxelForge`. The sandbox did not permit creating the sibling `/home/jahni/VFHostL14`, so its second host project is nested at `/home/jahni/VFHost/VFHostL14/VFHostL14.uproject`. The supplied `/home/jahni/VFHost/VFHost.uproject` was restored byte-for-byte after testing. RealtimeMeshComponent's original source tree was not modified.
|
||
|
||
## Failed runs
|
||
|
||
- Initial builds hit a read-only UBT config path, then a read-only RMC intermediate timestamp, then a UBA stall. The next compile found Linux Unity duplicate test helpers; disabling Unity on Linux fixed it. A final incremental attempt made after restoring the original host descriptor again hit the RMC read-only timestamp; rebuilding with the local RMC copy passed.
|
||
- Two early trace launches rejected an output directory outside the host project. The next launch stopped on the absent staged character Blueprint. Stock UE template Blueprints then failed to provide a sprint value; the trace-only defaults got past that gate. Both final revisions then stopped at the identical SurfaceWorld route audit above.
|
||
|
||
There were 12 build invocations, within the 15-attempt Part A limit.
|
||
|
||
## Orchestrator review (Claude)
|
||
|
||
Accepted. **The Linux UE build compiles VoxelForge with 0 errors** (HEAD and L14). I checked that the Compat and
|
||
`Source/` changes don't alter Core output: standalone Clang and GCC rebuilds produce **identical whole-view hashes**
|
||
to `3202193` on the pre-U2 data, for both SW and FI. The RealtimeMeshComponent tree is unmodified: its 203 git "M"
|
||
entries are CRLF-only (empty diff with whitespace and CR ignored, no file newer than this round outside
|
||
Intermediate/Binaries). The Unreal trace is blocked for both L14 and HEAD by the **owner's new assets**:
|
||
`SurfaceWorld route candidates failed the capsule and support sweep` before `AVoxelWorld` spawns (consistent with
|
||
L64: SW route 24/33 unsupported). The `verify.py` tiers still assume the old two-strate owner data and fail on the U2
|
||
export; they need a pinned regression dataset plus new-plan baselines. `Source/` files to include in the owner's next
|
||
Windows build are listed above.
